DP83869HMRGZR

DP83869HMRGZR - High-Immunity Gigabit Ethernet PHY | TI

The Texas Instruments DP83869HMRGZR is an extended-temperature, high-immunity gigabit Ethernet PHY transceiver with integrated PMD sublayers, supplied in a 48-pin VQFN (RGZ) 7x7 mm package. It supports 10BASE-Te, 100BASE-TX, and 1000BASE-T copper protocols along with 1000BASE-X and 100BASE-FX fiber interfaces, operating from a 1.8V/2.5V/3.3V supply rail. An Ethernet PHY (Physical Layer transceiver) is the interface IC that connects a MAC (Media Access Controller) to the physical copper or fiber cable, handling line coding, link training, echo/return-loss compensation, and clock/data serialization. As part of the Physical Layer transceiver -> Ethernet transceiver -> Network Interface IC -> Power Management/Connectivity IC hierarchy, gigabit PHYs sit one layer below the MAC and one layer above the magnetics/RJ-45 (or SFP fiber cage), translating MII/GMII/RGMII parallel data into differential serial signals compliant with IEEE 802.3 10/100/1000BASE-T. Key features of the DP83869HMRGZR include: IEEE 802.3 10/100/1000 Mbps operation, integrated PMD sublayers for copper and fiber, RGMII/MII/GMII MAC interfaces, media-conversion between copper and fiber ports, AEC-Q100-qualified extended-temperature grade (-40C to +125C), low-latency cut-through mode, and 8 kV IEC 61000-4-2 ESD protection (direct contact). The 48-pin VQFN (RGZ) package exposes a thermal pad for heat dissipation and supports reflow soldering on standard industrial PCB processes. Architecturally, the DP83869HMRGZR integrates the entire physical coding sublayer (PCS), physical medium attachment (PMA), and physical medium dependent (PMD) blocks on-chip, eliminating the need for external PHY magnetics tuning circuits. The device supports both SGMI and RGMII host interfaces with selectable timing modes, and includes integrated termination resistors that simplify the BOM. Cable diagnostics, loopback modes, and jumbo-frame support extend its utility in industrial Ethernet switches. Typical applications include industrial Ethernet switches, factory automation controllers, motor-drive communication boards, 5G small-cell fronthaul, automotive Ethernet gateways, and fiber-to-copper media converters. The wide temperature and high immunity make it well suited for IEC 61000-4 industrial EMC environments where standard PHYs would fail conformance. When designing with this part, ensure the MDI traces are 100-ohm differential with controlled 50-ohm single-ended impedance, place the 1.8V/2.5V/3.3V decoupling capacitors within 2 mm of each supply pin, and use a 4-layer PCB with a continuous ground plane below the PHY to meet IEEE 802.3 return-loss masks.

DP83901AV

DP83901AV - 5V Serial Network Controller | Texas Instruments

The Texas Instruments DP83901AV is a 5 V serial network interface controller, or SNIC, with 110 mA typical supply current in a 68-pin PLCC J-lead package measuring 25.13 mm by 25.13 mm. Designed for CSMA/CD local-area networks, the device supports Ethernet 10BASE5, Thin Ethernet 10BASE2, and twisted-pair Ethernet 10BASE-T implementations. A serial network interface controller is a semiconductor that coordinates data exchange between a host computer and an Ethernet physical layer. Within the network-interface hierarchy, it sits between host hardware or software drivers and a network-medium transceiver. The DP83901AV consolidates functions required to manage Ethernet packet transfer, addressing, access, and station communication while operating from a single 5 V supply. The verified source material identifies the DP83901AV as a microCMOS VLSI controller with a serial interface, 7 pF typical input capacitance, and 7 pF typical output capacitance under the stated test conditions. Its nominal 110 mA supply current makes board-level power planning important in systems that operate continuously. Commercial temperature grade and tray packaging are also identified in the verified component listings. Because the part targets legacy Ethernet standards, its strongest design roles are 10BASE5, 10BASE2, and 10BASE-T network-interface designs rather than modern switched Gigabit Ethernet equipment. A host processor must provide the required bus, interrupt, memory, and network-driver environment. Designers should also preserve the exact timing, signal-conditioning, and pin functions documented for this legacy controller. Typical implementation choices include industrial data acquisition, embedded test systems, service equipment, and legacy Ethernet adapters that require 10BASE-T connectivity. The controller can be paired with suitable transceivers, magnetics, isolation, clocks, and termination networks, but the external network interface must be selected independently because the verified data does not identify one specific companion-device BOM. The primary design consideration is availability and lifecycle validation. This is a mature Ethernet controller, so procurement should confirm current supply, manufacturer status, and traceability before a new design is released. Existing products should preserve the original schematic, timing, and firmware assumptions unless a replacement has been independently qualified. This page consolidates the verified package, supply, interface, and Ethernet data while separating unavailable specifications from established facts. It also records the lack of a verified drop-in replacement rather than presenting a functionally similar controller as a safe PCB substitute.

DP83902AV/NOPB

DP83902AV/NOPB - 10BASE-T Ethernet Controller

Texas Instruments DP83902AV/NOPB is an IEEE 802.3 serial network interface controller for 10BASE-T twisted-pair Ethernet, with a 4.75 V to 5.25 V supply range, 140 mA supply current, and an 84-pin PLCC package measuring 29.31 mm by 29.31 mm. It integrates the network-controller and twisted-pair transceiver functions required by legacy 10 Mb/s Ethernet systems. An Ethernet controller is an interface IC that connects a host or embedded system to a physical-layer network. The DP83902AV/NOPB belongs to the ST-NIC family and is intended for IEEE 802.3 10BASE-T networking. Unlike a switching Ethernet transceiver designed for modern 100 Mb/s or multi-gigabit links, this device targets legacy 10BASE-T equipment where established system architecture and installed cabling remain important. The device operates from a conventional 5 V supply, accepting voltages from 4.75 V through 5.25 V. Its specified supply current is 140 mA. The package is an 84-pin J-lead PLCC with a 29.31 mm by 29.31 mm body, and the documented shipping format is a tube. The suffix NOPB identifies a lead-free ordering configuration associated with this manufacturer’s RoHS-compliant product documentation. DP83902AV/NOPB combines the logical Ethernet controller and 10BASE-T physical interface in one integrated circuit. This integration reduces the number of network-interface components required in a conventional 10BASE-T design. The serial interface is consistent with the ST-NIC architecture used in IEEE 802.3 systems, allowing the controller to serve as the principal interface between host-side logic and the twisted-pair physical layer. Typical uses include legacy network interface cards, embedded industrial Ethernet equipment, test systems, and industrial-control products whose original architecture was designed around the IEEE 802.3 10BASE-T standard. The device may also appear in equipment maintenance and obsolescence programs where preserving the original 84-pin PLCC footprint is preferable to redesigning the network interface. A replacement decision should prioritize the complete pinout, electrical characteristics, clocking arrangement, media-access behavior, and software-driver expectations. Do not assume that another Ethernet controller is interchangeable solely because it also supports 10BASE-T. A qualified replacement must preserve the 84-pin PLCC land pattern and the original system-level timing and register requirements. This product page combines the controller identity, operating limits, package information, verified drop-in information, comparison parameters, and engineering selection guidance. That practical context helps engineers distinguish a genuine footprint-compatible replacement from a merely similar Ethernet interface before committing to a redesign.

DP83902AVLJ

DP83902AVLJ - 5V Serial Network Controller | Texas Instruments

The Texas Instruments DP83902AVLJ is a serial network interface controller for twisted-pair networks, supplied in a 100-lead rectangular QFP package and operating from a 4.75 V to 5.25 V supply. Its listed characteristics include a serial interface, approximately 140 mA supply current, commercial temperature grade, and tray packaging. The device is described by Texas Instruments as an ST-NIC serial network interface controller and is categorized as an obsolete interface controller. A serial network interface controller is an integrated circuit that manages the communication path between a computer or embedded system and a network medium. In the product hierarchy, this controller belongs to interface ICs and ultimately to the broader semiconductor category. The DP83902AVLJ was designed around twisted-pair network connectivity, where a physical-layer transceiver is commonly paired with a controller. The controller handles network framing and data exchange, while the external transceiver performs signal encoding, reception, and electrical isolation from the copper medium. The DP83902AVLJ uses a 4.75 V minimum and 5.25 V maximum supply voltage, giving system designers a nominal 5 V operating rail. The verified distributor listing reports a supply current of 140 mA. Its 100-pin QFP package provides a substantial number of external connections, which is typical for legacy Ethernet controllers that require parallel host data paths, address and control signals, clocking, interrupt signaling, and twisted-pair transceiver interfaces. Package dimensions, pin names, operating-temperature limits, Ethernet data rate, transceiver interface details, and electrical timing limits are not included in the supplied verification data. The DP83902AVLJ is most relevant to legacy networking equipment, industrial control systems, embedded controllers, and industrial Ethernet designs that already use this controller and its associated application circuitry. It should not be assumed interchangeable with a modern Ethernet controller merely because both perform networking functions. The verified cross-reference material specifically states that the STMicroelectronics SERC816/TR is not a direct drop-in replacement because its pinout, internal biasing, and MII timing characteristics differ. A PCB replacement therefore requires a detailed electrical, timing, and pin-level review rather than a simple component substitution. This page consolidates the verified distributor specifications, lifecycle information, sourcing details, and replacement constraints for DP83902AVLJ. Pricing is presented as unavailable because the verified sources provide quote or request-for-quotation terms rather than numeric unit prices. The pin table records all 100 package terminals but marks individual terminal names as unavailable rather than guessing pin functions. Engineers should obtain the manufacturer datasheet and original design reference before layout changes, firmware updates, or obsolescence redesigns.

DP83905AVQB

DP83905AVQB - 10BASE-T Ethernet Controller | Texas Instruments

The Texas Instruments DP83905AVQB is an AT/LANTIC AT local-area-network twisted-pair interface controller with an integrated IEEE 802.3 10BASE-T PHY, an ISA interface, and a 160-pin QFP package measuring 28 mm by 28 mm. It operates from a single 4.75 V to 5.25 V supply and is specified for 0 °C to 70 °C commercial-grade operation. An Ethernet controller integrates the digital protocol, media-access, and physical-layer functions needed to connect a legacy personal computer or embedded ISA bus to a 10BASE-T twisted-pair network. The DP83905 supports the AT/LANTIC protocol family, IEEE 802.3 operation, and 10BASE-T signaling. Because the physical layer is integrated, a compliant design can use the controller with the appropriate line-driver, filter, isolation, and magnetics interface rather than implementing the complete PHY separately. Verified device attributes include a 4.75 V to 5.25 V supply range, nominal 100 mA supply current, IEEE 802.3 network support, 10BASE-T PHY operation, ISA host interfacing, a commercial temperature grade of 0 °C to 70 °C, and a 160-BFQFP package. The device is identified as obsolete in the supplied manufacturer-related documentation, so it is most appropriate for maintenance of legacy AT-compatible networking equipment rather than new mass-production designs. The DP83905AVQB belongs to the former National Semiconductor controller portfolio now served by Texas Instruments. Its large 160-pin gull-wing QFP construction is characteristic of late-1980s and early-1990s PC interface controllers, when integrating the AT bus logic, network controller, and 10BASE-T PHY into one device reduced component count and simplified legacy adapter-card design. Typical uses include industrial legacy controllers, AT-compatible Ethernet adapters, embedded data-acquisition systems, and repair or obsolescence-management programs for installed networking equipment. The ISA interface and 10BASE-T speed make the device most suitable for systems that already rely on the AT/LANTIC environment; it is not a modern 100BASE-TX or gigabit Ethernet controller. When replacing this component, engineers should verify the complete 160-pin footprint, exposed pad requirements, power rails, oscillator components, magnetics isolation, and legacy bus termination before substituting. Because this part is obsolete and few verified pin-compatible replacements are documented, board-level redesign to a current Ethernet controller may be safer than assuming equivalent availability.

DP83907VF

DP83907VF - 10Base-T Ethernet NIC Controller ISA Interface | TI

The Texas Instruments DP83907VF (AT/LANTIC II) is a single-chip CMOS VLSI 10Base-T Ethernet Network Interface Controller (NIC) with integrated ISA bus interface, delivered in a 132-pin BQFP (PQFP) package. It supports a single 10 Mb/s twisted-pair or coaxial channel, operates from a single 5V supply (4.75 V to 5.25 V) drawing approximately 150 mA, and is qualified to the commercial temperature range. What is an Ethernet NIC controller? A NIC controller is an integrated circuit that bridges a host processor's parallel bus (such as ISA, PCI, or PCIe) to a Media Access Control layer that implements the CSMA/CD protocol used by IEEE 802.3 Ethernet. The DP83907 sits in the hierarchy: 10Base-T PHY → Ethernet MAC → NIC controller → host bus controller → PC motherboard. By integrating the entire PC-AT ISA bus interface along with the MAC and 10 Mb/s physical front-end, the DP83907 reduces discrete component count and lets designers add a 10 Mb/s LAN port with minimal glue logic. Key features of the DP83907VF include on-chip Manchester encoder/decoder for 10Base-T, integrated 10Base-T transceiver (twisted-pair), built-in attachment unit interface (AUI) for external MAU support, full ISA (Industry Standard Architecture) 8/16-bit bus mastering DMA engine, and configurable I/O and memory mapped modes. The device offers a 2-channel CSMA/CD link, supporting 1.25 MBps raw throughput on the serial side. CMOS process technology keeps power dissipation under 1W typical. Architecturally, the DP83907VF partitions cleanly into a bus interface unit, a CSMA/CD MAC engine, a Manchester ENDEC, and a 10Base-T analog front end. The MAC performs framing, CRC-32 generation/checking, collision detection, and back-off timing, while the analog front-end provides transmit waveshaping and receive equalization for 100-meter Category-3 cable runs. The combination targets PC-AT/PC/XT motherboards, ISA add-in cards, embedded LAN adapters, and industrial 10 Mb/s backbones. Typical applications include ISA-bus Ethernet NIC add-in cards, factory-floor 10Base-T bridges, industrial automation controllers with embedded LAN ports, legacy PC motherboard LAN-on-board designs, and 10 Mb/s repeaters/hubs requiring a host-managed controller. Because the part integrates the AUI option, it can also drive an external 10Base2 (BNC) transceiver for coax-based legacy LANs. When designing with the DP83907VF, plan ISA bus arbitration because bus-master DMA requires care to coexist with other bus masters. Add 4.7 kΩ pull-ups on configured strap inputs (IRQ, I/O base address) and keep the analog ground (AGND) and digital ground (DGND) separated under the package, joining them only at the PCB main ground plane to preserve 10Base-T jitter margins.

DP8390DV

DP8390DV - 10 Mbps 5 V Ethernet NIC | Texas Instruments

The Texas Instruments DP8390DV is a 10 Mbps, 5 V Ethernet network interface controller supplied in a 68-pin PLCC package measuring 25.13 mm by 25.13 mm. It is designed to interface host systems with CSMA/CD local-area networks, including Ethernet Thin implementations, while presenting a dedicated network-controller function rather than requiring the host processor to manage the physical network medium directly. The verified distributor listing identifies the device as an Ethernet controller interface and describes its 68-PLCC construction. What is an Ethernet network interface controller? An Ethernet NIC is an interface IC positioned between a computer or embedded controller and an Ethernet physical layer. It handles network-oriented communication tasks and reduces the electrical and protocol burden placed on the host system. In the broader semiconductor hierarchy, the DP8390DV is a communication interface controller, an interface IC, and ultimately a semiconductor used in Ethernet networking equipment and embedded data-processing systems. The DP8390DV’s primary verified characteristics include a 10 Mbps data rate, a 5 V supply, and approximately 40 mA supply current. Those values place it in the established 10BASE-T-era Ethernet hardware category. Its PLCC package provides a surface-mount PCB footprint with J-leads, while the listed 25.13 mm by 25.13 mm body size supports compact but not especially miniature industrial and legacy-compatible designs. DP8390D-family devices were designed to ease host interfacing with CSMA/CD local-area networks, including Ethernet Thin networks. The controller therefore belongs in systems where a host bus must communicate through an Ethernet-compatible network interface. Compared with a general-purpose interface IC, its defining value is Ethernet-specific integration: the network function is consolidated into a dedicated controller rather than being implemented entirely with host firmware and discrete logic. Typical uses include embedded Ethernet controllers, industrial data-acquisition systems, legacy terminal equipment, print servers, network-interface modules, and host adapters designed around the DP8390 family. In these applications, the DP8390DV can serve as the network-facing IC while an external transceiver, magnetic interface, connector, and system controller provide the surrounding physical-layer and host-side implementation. The principal design consideration is that this is a mature 10 Mbps controller rather than a current multi-gigabit Ethernet PHY or modern system-on-chip interface. Board design must follow the manufacturer pinout and required external components exactly. Signal routing, supply decoupling, thermal exposure, and network magnetics or transceiver selection should be validated against the official DP8390 documentation before layout release. This page consolidates verified distributor specifications, sourcing information, interface context, and application guidance. It does not invent unprovided pin assignments, timing values, temperature limits, or replacement parts, so unavailable engineering data remains explicitly marked rather than being inferred.

DP83910AN

DP83910AN - CMOS Serial Network Interface 24-DIP | National Semiconductor

The National Semiconductor (Texas Instruments) DP83910AN is a CMOS Serial Network Interface (SNI) IC that provides Manchester data encoding and decoding for IEEE 802.3 Ethernet networks, supplied in a 24-pin DIP through-hole package (0.300 inch, 7.62 mm body width) and operating from a single 4.75 V to 5.25 V supply. The device is a direct-pin functional replacement for the legacy bipolar DP8391 SNI, integrating the physical-layer attachment functions required to interface an Ethernet transceiver (such as the DP8392 or DP839CT) to a controller or terminal-end Manchester encoder/decoder across 10 Mb/s Thin Ethernet (10BASE2/10BASE5) topologies. A Serial Network Interface (SNI) is a category of interface IC that sits between the Ethernet coaxial transceiver and the system controller, performing Manchester encoding, clock recovery, jabber monitoring, and link-integrity signalling per the IEEE 802.3 physical-layer specification. Within the broader hierarchy, the DP83910AN belongs to the network interface IC family, which falls under interface ICs, then integrated circuits, then semiconductors, providing OSI layer-1 connectivity and isolating the host CPU from line-coding analogue details. Key features include 10 Mb/s Manchester encoding/decoding, integrated jabber detection and Link Test generation, CMOS low-power operation versus the original bipolar DP8391, and a wide supply tolerance of 4.75 V to 5.25 V. The 24-DIP through-hole package supports easy insertion into legacy Ethernet adapter boards and industrial retrofit designs, while the CMOS process reduces typical operating current compared to its bipolar predecessor. The device also provides collision-detection and carrier-sense signalling flags that flow into the upper-layer MAC controller. Architecturally, the DP83910AN combines a phase-locked loop (PLL) for receive clock recovery, a 10 MHz oscillator interface, transmit clock-generation logic, and differential Manchester encode/decode blocks. Because the silicon is a drop-in CMOS replacement for the DP8391, existing schematic layouts can accept the DP83910AN without board rework, a critical advantage for legacy industrial networks and instrumentation that depend on the older part. Typical applications include 10BASE2 / 10BASE5 Ethernet adapter cards, industrial SCADA controllers, legacy factory-floor networking interfaces, and embedded instrumentation that must communicate over IEEE 802.3 media. The DP83910AN is also commonly used by restoration projects for early-1990s networking hardware and by test equipment vendors supporting IEEE 802.3 physical-layer compliance. When designing with this device, note that the DP83910AN is now in obsolete/EOL lifecycle, so long-term sourcing requires attention to authorized distributor stock and the qualified cross-references listed in the alternatives section. Decoupling with 0.1 uF ceramic capacitors close to VCC/GND pins is essential for the integrated PLL to maintain stable clock recovery under varying line loading.

DP83910AV

DP83910AV - CMOS SNI Ethernet Interface | Texas Instruments

The Texas Instruments DP83910AV is a CMOS Serial Network Interface (SNI) integrated circuit with a 28-PLCC J-lead package. The supplied distributor data identifies it as an Ethernet network interface operating from a 4.75 V to 5.25 V supply and supporting a commercial temperature grade of 0 C to 70 C. The DP83910A family provides Manchester data encoding and decoding functions for IEEE 802.3 Ethernet Thin Ethernet local-area networks and is described as a direct-pin equivalent of the bipolar DP8391 SNI. A Serial Network Interface is an interface integrated circuit that converts between a host-side digital data stream and the physical signaling required by a legacy Ethernet network. In the product hierarchy, SNI belongs to network interfaces, then interface ICs, then integrated circuits. Manchester encoding represents each data bit through a transition pattern, allowing the receiver to recover both the bit value and clock information from the serial waveform. This device is therefore intended for systems requiring legacy Ethernet-compatible Manchester encoding and decoding rather than a modern integrated PHY/MAC solution. The DP83910AV is specified as a 28-pin PLCC device, with the AV suffix identifying the supplied package/orderable configuration. Its 4.75 V to 5.25 V operating range is characteristic of a 5 V legacy interface implementation. Distributor listings classify the device as an Ethernet Network Interface IC, while the manufacturer-related datasheet description identifies it as a CMOS SNI Serial Network Interface. The available source data does not provide verified values for clock rate, current consumption, output timing, logic levels, or internal transceiver details. Typical engineering uses include legacy Thin Ethernet network nodes, industrial data-collection equipment, embedded test systems, and retrofits requiring compatibility with existing Manchester-encoded Ethernet hardware. In such systems, the DP83910AV can perform the Manchester encoding or decoding stage at the boundary between digital logic and the network interface. The 28-PLCC package is a legacy surface-mount format requiring a matching footprint, adequate routing clearance, and careful examination of pin orientation and thermal performance. For new designs, verify that the required legacy network architecture, voltage, timing, connector, and isolation requirements match the device. Obsolete or NRND legacy Ethernet components should be sourced only after confirming documentation, traceability, and long-term availability. The available distributor result reports 6,224 pieces in stock and a unit price of $9.5471, but price and availability should be reconfirmed at the time of purchase. This page combines verified distributor descriptions, lifecycle information, package data, and engineering-use guidance.

DP83910AV/63

DP83910AV/63 - 5V Ethernet SNI Interface | Texas Instruments

The Texas Instruments DP83910AV/63 is a 5 V CMOS serial network interface IC designed for Ethernet network-interface applications, supplied in a 28-pin PLCC surface-mount package measuring approximately 11.51 mm by 11.51 mm. The device operates from 4.75 V to 5.25 V and is specified for a 0°C to 70°C temperature range. Verified distributor data identifies it as a tape-and-reel packaged Ethernet network interface with a serial interface architecture. An Ethernet serial network interface, or Ethernet SNI controller, is an interface IC within the broader network interface controller and Ethernet controller categories. Its function is to connect a host or processor-side system to Ethernet physical-layer circuitry, handling the serial-side data path and associated control signals. The DP83910AV/63 therefore belongs to the integrated-circuit hierarchy: Ethernet interface controller, network interface controller, Ethernet IC, and semiconductor. Key verified features include a 4.75 V to 5.25 V supply range, a 0°C to 70°C commercial operating-temperature range, and a 28-pin PLCC package. The source data identifies the part as an Ethernet network interface with a serial interface and CMOS construction. The verified product listing also states that the device contains lead and is not RoHS compliant. Detailed electrical characteristics such as clock frequency, transceiver-interface timing, maximum output current, and pin-level functions were not included in the supplied verified data and therefore are not asserted here. The DP83910AV/63 is primarily associated with legacy embedded Ethernet equipment, industrial controllers, communication modules, and systems requiring an IEEE 802.3-compatible Ethernet path. The surrounding system must provide the correct supply regulation, decoupling, physical-layer transceiver, isolation requirements, connector protection, and clocking. Because the verified source describes a legacy PLCC device that is not RoHS compliant, engineers should review current regulatory, availability, and lifecycle requirements before starting a new design. A key design consideration is PCB compatibility. The 28-pin PLCC footprint requires a matching surface-mount land pattern and appropriate assembly temperature controls. Do not substitute a functionally similar but mechanically different controller without verifying every pin, supply requirement, timing parameter, and signal standard. For legacy repairs, confirm whether the original board uses the /63 tape-and-reel ordering code and verify the manufacturer documentation for assembly and handling requirements. This page consolidates verified distributor facts, lifecycle-related availability information, direct substitution references, and practical selection guidance. It also distinguishes documented electrical facts from unavailable parameters so engineers can assess the DP83910AV/63 without mistributing catalog summaries for a complete datasheet specification set.

The Texas Instruments DP83910AV/63SN is a CMOS serial network interface (SNI) integrated circuit for Ethernet network-interface designs, supplied in a 28-pin PLCC package measuring 11.51 mm by 11.51 mm. The device operates from a 4.75 V to 5.25 V supply, uses a commercial temperature grade, and is supplied in a tube according to the product comparison record. An SNI, or serial network interface, is an interface integrated circuit that connects networking equipment to a serial or system-side data path. Within the hardware hierarchy, the DP83910AV/63SN belongs to Ethernet interface ICs, network interface controllers, interface semiconductors, and integrated circuits. Its function is to support Ethernet-oriented network-interface implementations where a dedicated controller requires a compatible serial network interface device. The principal documented characteristics are the 4.75 V to 5.25 V operating supply, CMOS construction, 28-pin PLCC package, and 11.51 mm by 11.51 mm package dimensions. The DP83910AV/63SN carries RoHS3 status and is identified as a last-time-buy component. Engineers should therefore treat availability, lifecycle continuity, and legacy-board support as important selection factors rather than assuming a current active-production lifecycle. The DP83910A is designed as a CMOS SNI for Ethernet applications. Because this legacy device predates many integrated Ethernet controllers, it is most relevant to equipment based on established interfaces, industrial communication systems, test equipment, and embedded networking designs that retain the original system architecture. A migration to a newer Ethernet interface IC may require controller, protocol, pinout, software, and timing changes rather than a simple board substitution. Typical uses include legacy Ethernet network-interface adapters, industrial control equipment, embedded communication controllers, test and measurement systems, and data-acquisition equipment. In these applications, the SNI can serve as the network-facing interface component while a host processor or communications controller manages packet processing and higher-level protocol functions. The 5 V supply range also supports equipment architectures that already provide a regulated 5 V rail. When designing around the DP83910AV/63SN, begin with the manufacturer datasheet pin-description table, supply recommendations, and timing diagrams. PLCC lead pitch, exposed underside geometry, solder-profile requirements, and thermal performance should be checked against the PCB footprint before layout approval. Because the device is in last-time-buy status, consider long-term procurement and a documented second-source strategy for maintenance programs. This page organizes the known electrical, package, lifecycle, commercial, and replacement information for engineering review. It also highlights verified direct-substitute information and explains where an existing Ethernet design may require architectural changes instead of a pin-compatible replacement.

DP83910AV/NOPB

DP83910AV/NOPB - CMOS Ethernet SNI | Texas Instruments

Texas Instruments DP83910AV/NOPB is a CMOS serial network interface (SNI) integrated circuit for Ethernet network equipment, with a 4.75 V to 5.25 V supply range and a 28-pin PLCC package measuring 11.51 mm by 11.51 mm. The device provides Manchester data encoding and decoding functions while remaining a direct-pin equivalent of the bipolar DP8391 serial network interface. A serial network interface is an interface IC that connects a digital system to a physical network encoding. Manchester encoding represents each bit through a transition in the signal, allowing the receiver to recover both data and timing. Within the broader semiconductor hierarchy, the DP83910AV/NOPB is an Ethernet interface IC, a serial interface device, and a network interface component designed for 5 V digital equipment. Key features include CMOS construction, serial Manchester encoding and decoding, a 4.75 V minimum operating supply, a 5.25 V maximum operating supply, and compatibility with the pin arrangement of the original bipolar DP8391 interface. Its commercial temperature classification, J-lead terminal form, 28-terminal square package, and tube packaging are identified in manufacturer and distributor technical listings. The DP83910A implementation replaces the bipolar technology used by the earlier DP8391 while retaining direct-pin equivalence. This distinction is important in legacy and industrial Ethernet designs because a board can retain its established land pattern and signal architecture while moving from a bipolar interface to CMOS. The 28-PLCC construction also supports through-hole assembly and removal or replacement with conventional PLCC handling equipment. Typical uses include Ethernet network interface cards, embedded Ethernet equipment, industrial controllers, data acquisition systems, and legacy network adapters that require Manchester-coded serial signaling. The appropriate operating environment must stay within the stated 4.75 V to 5.25 V supply range. Board-level design should also preserve the original DP8391-compatible clock, transmit, receive, and control arrangements when reusing an existing footprint. For a new design, begin with the manufacturer pin-description and application information rather than treating the direct-pin statement as permission to change system timing. Decoupling, impedance-controlled network connections, grounding, and signal routing should follow the circuit shown in the manufacturer datasheet. In a legacy replacement, verify the installed DP8391 or DP83910A markings and compare supply voltage, temperature grade, and package orientation before production use. This page combines the verified package, supply, interface, technology, and compliance details with replacement guidance and practical implementation considerations. It also identifies the limitations of the available drop-in choices: the closest documented replacement is the same manufacturer's DP83910AV/63, while no additional pin-compatible component is documented by the cited TI support discussion.

DP83924BVCE

DP83924BVCE - Quad 10 Mb/s Ethernet PHY | Texas Instruments

The Texas Instruments DP83924BVCE is a quad-port 10 Mb/s Ethernet physical-layer transceiver integrated circuit with a 4.75 V to 5.25 V supply range in a 100-PQFP package. It combines four twisted-pair PHY channels and a programmable MAC interface supporting most standard seven-signal MAC interfaces, providing a consolidated physical-layer solution for multiport Ethernet equipment. An Ethernet physical layer, or PHY, is the interface between a Media Access Controller and physical network media. A PHY converts digital frames and control signals into electrical signaling suitable for a physical layer, while receiving and decoding incoming signals. Within the Ethernet hierarchy, the DP83924BVCE is an Ethernet interface IC, a physical-layer transceiver, a network-interface semiconductor, and ultimately a power-management-dependent mixed-signal component. The device provides four 10 Mb/s Ethernet ports, on-chip transmit-output filters, and a common four-port twisted-pair transceiver structure. Its 4.75 V minimum and 5.25 V maximum operating supply span supports conventional 5 V equipment designs. According to the manufacturer datasheet, the programmable MAC interface supports most standard seven-signal MAC interfaces, reducing the need for separate physical-layer devices when four network ports share one controller. The DP83924B architecture organizes the four PHY channels behind a configurable interface to a MAC or repeating-device controller. This multiport arrangement is intended to simplify board-level networking designs while preserving separate twisted-pair channels for each port. Because the available verified material does not enumerate every internal filter, equalization, timing, or link-detection parameter, those values should be taken directly from the current manufacturer datasheet before final signal-integrity or network compliance sign-off. Typical uses include four-port hubs and repeaters, concentrators, printed-circuit-board Ethernet switches, industrial network interfaces, test equipment, and legacy 10 Mb/s terminal systems. In each case, the quad-port organization is valuable when a controller has enough I/O capacity to service four separate MAC channels and the PCB can accommodate the associated magnetics or twisted-pair network connections. Designers should pay close attention to 5 V supply decoupling, the 100-pin quad-flat-package footprint, trace routing around each PHY channel, and the external magnetic components required by the implemented network topology. The available data identifies tube packaging and a commercial temperature grade, but it does not provide complete verified dimensions, pin names, absolute maximum ratings, or electrical test conditions. This page combines the verified distributor and manufacturer-linked specifications with practical integration guidance, package details, application context, pricing caveats, and drop-in replacement analysis. It also distinguishes verified facts from unavailable technical data so procurement and engineering teams can identify the exact information that still requires confirmation from the authoritative DP83924B datasheet.

DP8392CN-1

DP8392CN-1 - IEEE 802.3 Coaxial Transceiver | Texas Instruments

The Texas Instruments DP8392CN-1 is an IEEE 802.3 coaxial transceiver interface with 16 through-hole DIP terminals, a nominal -9 V supply, and a commercial operating-temperature grade of 0°C to 70°C. It is designed to connect a coaxial Ethernet physical-layer cable to data-terminal equipment through transmit and receive signal paths. The verified listing identifies the device as a CTI, or Coaxial Transceiver Interface, and classifies it as an Ethernet transceiver rather than a general-purpose transceiver. Its legacy application is Thin Ethernet, or 10BASE-2, where the transceiver connects a station or network node to a coaxial bus. A coaxial transceiver interface is an interface IC that integrates the electrical functions needed to communicate over a shielded coaxial cable. In the broader networking hierarchy, it belongs to the network-interface and communications-semiconductor categories, where a physical-layer transceiver works alongside a network controller or system data bus. The DP8392CN-1 is therefore most useful when maintaining, repairing, or reproducing a legacy 10BASE-2 Ethernet design rather than designing a new modern Ethernet system. Its 16-DIP package favors through-hole construction and serviceable legacy equipment. Key verified attributes include the 16-terminal rectangular DIP package, through-hole terminal form, nominal -9 V negative supply, commercial temperature grade, and a listed 19.305 mm length. The device is identified as suitable for Ethernet transceiver applications and supports the coaxial cable line-driver and receiver function. The verified data does not provide output impedance, propagation delay, receiver sensitivity, isolation voltage, or detailed timing values, so those parameters should not be inferred from the product family without an applicable manufacturer document. Typical applications include legacy Thin Ethernet terminal adapters, coaxial network-interface cards, industrial or communications equipment retaining a 10BASE-2 port, and repair or restoration of older Ethernet hardware. The -9 V supply requirement must be checked against the surrounding circuit; it is not a modern 3.3 V or 5 V plug-in-compatible rail. The 16-pin through-hole footprint also requires mechanical and pin-level verification before replacement. The most important design consideration is that a coaxial transceiver is not interchangeable with every Ethernet transceiver having the same network function. Confirm the exact pinout, supply polarity, cable termination, connector type, and signal-level requirements in the applicable datasheet before layout or schematic changes. For new designs, verify that the legacy 10BASE-2 requirement is intentional; modern 10/100/1000 Ethernet generally uses different physical-layer devices. This page combines the verified distributor and manufacturer-source identification with package, application, and sourcing context. It distinguishes confirmed DP8392CN-1 facts from parameters that remain unavailable, rather than filling gaps with assumptions or unsupported substitutions.

DP8392CV-1

DP8392CV-1 - Coaxial Transceiver Interface (CTI) | Texas Instruments

The Texas Instruments DP8392CV-1 is a Coaxial Transceiver Interface (CTI) for IEEE 802.3 Ethernet networks, integrating a 10BASE2/10BASE5 coaxial line driver and receiver with collision detection and a built-in jabber timer in a 28-pin PLCC (V28A) surface-mount package. The device operates as part of the classic DP8390/DP8391/DP8392 chipset, providing the physical-layer interface between a DTE and a coaxial cable segment with on-chip transmit/receive switching and heart-beat generation. A Coaxial Transceiver Interface (CTI) is a type of network transceiver IC that connects a Medium Access Controller (MAC) to a coaxial Ethernet bus, performing electrical line driving, signal recovery, collision detection (signal-quality error pulse generation), and jabber fault isolation. CTIs are a subset of physical-layer (PHY) transceivers that sit between the MAC block and the cable medium, and are descendants of early 10 Mb/s Ethernet silicon that pre-dated modern twisted-pair PHYs in the OSI model's physical layer of the network stack. Key features of the DP8392CV-1 include a 10 Mb/s Manchester-encoded data rate, a single +5 V supply operation, integrated transmit/receive path switching, integrated SQE (Signal Quality Error) test pulse generation, a built-in jabber timer with automatic transmitter disable after the maximum packet time, and a TTL/CMOS-compatible interface to the DP8390 NIC and DP8391 encoder/decoder devices. The 28-PLCC pinout uses J-bend surface-mount leads and is organized for direct cable-side and digital-side pin groups to simplify PCB layout. The architecture uses a bipolar driver for the coaxial interface with separate transmit and receive amplifiers, a 10 MHz fundamental oscillator with external clock-reference support, and an analog collision-detection comparator that produces the standard heart-beat pulse during inter-packet gaps. The on-chip jabber latch disables the transmitter if a continuous transmit exceeds the packet-time threshold, protecting the coax segment from stuck-node faults. Commercial-grade temperature range (0C to +70C) targets office and lab Ethernet environments. Typical applications include 10BASE2 (Thin Ethernet / Cheapernet) network interface cards, 10BASE5 (Thick Ethernet) AUI-to-coax converter adapters, legacy industrial Ethernet backbones on coax, and embedded systems that require an IEEE 802.3 coax link to communicate with vintage networking equipment or to bridge older industrial fieldbus hardware. The part also sees use in test equipment that emulates a coax segment endpoint. When designing with this device, observe AC termination and DC bias requirements specified in the datasheet typical application - a 1:1 pulse transformer on the Tx/Rx line and external pull-up/pull-down resistors on collision and receive-data lines. Decoupling should keep the +5 V supply near the analog VCC pins with both bulk and 0.1 uF ceramic capacitors to prevent noise from coupling into the receive path.

DP83932BVF-25

DP83932BVF-25 - Ethernet Controller | Texas Instruments

Texas Instruments DP83932BVF-25 is an Ethernet controller with an IEEE 802.3 network interface, a 4.75 V to 5.25 V supply range, and a 132-pin PQFP package measuring 24.13 mm by 24.13 mm. The -25 suffix identifies a specific ordering variant within the DP83932 family, while BVF identifies the surface-mount quad flat package. This controller is intended for scalable LAN-node equipment requiring integrated Ethernet connectivity and a conventional parallel host interface. An Ethernet controller is a network interface controller that manages communication between a host processor and a physical Ethernet network. In the product hierarchy, it is an Ethernet interface IC, a peripheral interface controller, and a semiconductor designed for networking equipment. The DP83932BVF-25 belongs to the Texas Instruments SONIC family of Ethernet controllers, a product line historically developed for scalable and flexible LAN node designs. The verified data identifies the device as an IEEE 802.3 Ethernet controller supplied from 4.75 V to 5.25 V. One third-party technical listing reports a 100 mA supply current, while the DigiKey listing confirms the 132-PQFP package and commercial availability channel. These characteristics place the device in legacy and industrial networking designs where a 5 V Ethernet controller, parallel system interface, and exposed-lead quad flat package are practical. The BVF package uses 132 gull-wing terminals around a square body. Its relatively high pin count supports separate addressing, data, control, clock, interrupt, and network-side signals. Because the verified material does not provide a complete manufacturer pin table, individual terminal assignments cannot be transcribed safely. Engineers should use the manufacturer datasheet before PCB routing, particularly for supply, ground, reset, reference-clock, and signal-integrity connections. Typical uses include embedded industrial Ethernet nodes, print servers, automated test equipment, factory-control gateways, and legacy network-interface cards. In these systems, the controller provides the network-facing protocol and physical-interface control while the system processor handles higher-level services. A 4.75 V to 5.25 V operating supply allows integration with conventional 5 V logic systems, subject to the complete timing, electrical, and thermal limits in the datasheet. Designers should preserve the controller's required supply decoupling, provide a clean clock source, and route high-speed interface signals with controlled impedance and return paths. Because no verified price, detailed timing table, temperature range, clock requirement, or complete pin assignment was supplied, those values must be confirmed before schematic release. This page distinguishes verified facts from unavailable parameters rather than estimating them. This page combines verified distributor identification, family-level alternatives, practical Ethernet design guidance, and a parameter comparison framework that is not consolidated in a single distributor listing. It is intended to accelerate initial component selection while directing engineers back to the authoritative manufacturer documentation for final design decisions.

DP83932CVF-33

DP83932CVF-33 - 33MHz Ethernet Controller | Texas Instruments

Texas Instruments DP83932CVF-33 is a second-generation SONIC Ethernet network interface controller with a 5 V supply, a 32-bit or 16-bit system bus interface, and a 132-pin BQFP package. The controller is designed for high-speed 16-bit and 32-bit systems and uses DMA transfers that typically consume less than 3% of bus bandwidth at a 25 MHz bus clock. Selectable big-endian and little-endian byte ordering support integration across different host architectures. An Ethernet network interface controller is a semiconductor that manages data exchange between a host computer or embedded processor and an Ethernet network. The broader hierarchy is Ethernet controller → network interface controller → interface IC → integrated circuit. The SONIC architecture separates frame movement from the host processor, allowing Ethernet traffic to be transferred through DMA while the processor performs higher-level protocol processing. The DP83932CVF-33 provides a 5 V supply and supports both 32-bit and 16-bit host systems, as stated in the manufacturer datasheet. Its selectable bus byte ordering accommodates systems using either big-endian or little-endian conventions. The DMA interface is designed to limit bus utilization, with the datasheet stating that transfers typically consume less than 3% of bus bandwidth at 25 MHz. The controller is supplied in a 132-pin BQFP package identified as 24.13 mm by 24.13 mm in distributor data. Its exposed-lead package provides a large PCB footprint and external leads for system-bus, network-interface, timing, power, and control connections. The verified data identifies tray packaging and commercial-grade sourcing, while the exact operating-temperature limits and complete electrical timing tables were not included in the supplied excerpts. Typical uses include embedded Ethernet networking, industrial data acquisition, embedded logging, industrial controllers, computing modules, and firmware-boot or storage systems. The controller is appropriate where a host processor requires a dedicated Ethernet MAC with DMA-assisted transfers rather than handling every frame directly in processor software. When designing around the DP83932CVF-33, verify the complete 132-pin connection, network-interface circuit, oscillator requirements, reset behavior, and termination values against the manufacturer datasheet. PCB routing should keep high-speed bus and clock signals short, provide continuous ground-plane return paths, and include the decoupling network specified for the 5 V supply. This page combines verified distributor specifications, manufacturer-datasheet excerpts, sourcing information, structured drop-in family references, and practical integration guidance. It is designed to help engineers identify the correct controller package and evaluate DP83932CVF-33 for legacy Ethernet designs without obscuring which details remain to be confirmed from the full datasheet.

DP83934AVQB

DP83934AVQB - 10BASE-T Ethernet Controller | Texas Instruments

Texas Instruments DP83934AVQB is a 10BASE-T systems-oriented Ethernet network interface controller with a parallel host interface and integrated twisted-pair PHY, supplied in a 160-pin PQFP package measuring 28 x 28 mm. It operates from a 4.75 V to 5.25 V supply and has a reported supply current of 140 mA. An Ethernet network interface controller, or NIC, is an interface IC that connects a host or embedded processor to a physical network. The DP83934AVQB belongs to the broader SONIC-T systems-oriented controller family. It combines network packet processing, physical-layer connectivity for 10BASE-T, and a parallel processor-facing interface in one component, reducing the need for separate Ethernet-interface logic in legacy embedded systems. The verified product information identifies a 10BASE-T PHY, a parallel interface, and twisted-pair connectivity as its principal features. Its 4.75 V to 5.25 V operating-supply range is compatible with conventional 5 V embedded logic, while the 160 mA-class supply requirement makes suitable regulator capacity and supply-noise control important. The 160-pin PQFP exposes substantially more interface and control signals than a small-scale network controller. The device is associated with the SONIC-T 25 MHz systems-oriented architecture. For a legacy network design, the controller handles Ethernet frame activity while the host accesses registers and buffers through its parallel interface. A complete implementation also requires suitable memory, clocking, isolation or magnetics, cable termination, and power-supply arrangements defined by the applicable system design. Typical applications include industrial embedded controllers, legacy 10BASE-T network adapters, test equipment, embedded communications modules, and control systems requiring a deterministic parallel host interface. Its primary advantage is integration: one large-scale controller provides both the systems-oriented network interface and 10BASE-T physical-layer function rather than requiring a separate PHY. Engineers should verify the exact 160-pin pinout, clock requirements, memory interface, magnetic-component recommendations, and PCB layout constraints against the manufacturer datasheet before release. The large PQFP also requires careful escape routing, and the 4.75 V to 5.25 V supply must remain within the specified range at every point in the design. This product page consolidates the verified manufacturer and distributor information, separates confirmed electrical and packaging facts from unavailable data, documents replacement constraints, and provides application-specific engineering guidance that is not available from a distributor listing alone.

DP83934CVUL-20

DP83934CVUL-20 - 25MHz Ethernet NIC | Texas Instruments

Texas Instruments DP83934CVUL-20 is a 25 MHz SONIC-T systems-oriented network interface controller with a twisted-pair interface, packaged in a 160-pin PQFP. It operates from a 4.75 V to 5.25 V supply and is designed for 32-bit and 16-bit high-speed processor systems. The controller supports selectable 16-bit or 32-bit data paths, little-endian and big-endian bus operation, and integrated Ethernet framing, addressing, and packet handling. A network interface controller, or NIC, connects a processor or bus-based embedded system to an Ethernet network. The DP83934 belongs to the systems-oriented Ethernet controller family and combines a dedicated Ethernet data path with host-bus and twisted-pair connectivity. Its SONIC-T architecture separates network processing from the host bus, allowing demanding 32-bit systems to exchange packets without handling low-level Ethernet protocol work in the host processor. The principal operating characteristics include a 25 MHz controller clock, a selectable 16-bit or 32-bit host data path, and a 4.75 V to 5.25 V supply range. The 32-bit path doubles the parallel transfer width relative to the 16-bit option, while BMODE configuration supports little-endian systems and big-endian systems. The twisted-pair interface connects the controller to an Ethernet physical layer, and the manufacturer identifies the component as a systems-oriented network interface controller. The DP83934CVUL-20 is supplied in a 160-pin PQFP package and is packaged in a tube according to the distributor specification. Its comparatively high pin count provides dedicated parallel data, control, address, interrupt, and network-interface signals, reducing multiplexing and supporting a broad host-bus interface. The 140 mA supply-current specification describes the device's 5 V operating domain, while the 4.75 V to 5.25 V range provides conventional tolerance around a nominal 5 V rail. Typical applications include industrial Ethernet control equipment, embedded test systems, legacy 32-bit communications controllers, printed-circuit network interfaces, and embedded platforms that require a wide parallel host bus. The controller is especially relevant when an existing system already uses the SONIC-T interface and its associated software model. Modern designs with USB or compact embedded Ethernet links may instead favor newer interface architectures with smaller packages and lower host processing overhead. Board design should preserve the controller's synchronous bus timing, provide clean 5 V power, and route high-speed host and network signals with short, controlled paths. Differential Ethernet conductors should be routed as a pair with continuous reference planes, while reset, clock, and timing-critical signals require attention to datasheet timing constraints. Because this is a 160-pin PQFP device, fanout and escape routing demand a multilayer PCB and careful via planning around the fine-pitch package perimeter. This product record combines the manufacturer's controller description with package, interface, voltage, current, bus-width, and ordering information. It also provides drop-in replacement guidance, application-specific design considerations, and a parameter comparison intended to accelerate legacy Ethernet controller design, maintenance, and component-obsolescence reviews.

DP83934CVUL-25

DP83934CVUL-25 - 25 MHz Ethernet Controller | Texas Instruments

Texas Instruments DP83934CVUL-25 is a 25 MHz SONIC-T systems-oriented Ethernet network interface controller with a parallel interface and twisted-pair interface, housed in a 160-pin PQFP package measuring 28 mm by 28 mm. Its specified operating supply range is 4.75 V to 5.25 V, its operating supply current is 140 mA, and its commercial temperature range is 0 °C to 70 °C. An Ethernet network interface controller is an interface IC that connects a digital system to an Ethernet physical layer. It manages network-frame processing and provides the parallel data path required by compatible system logic. The DP83934 family belongs to the wider networking hierarchy of Ethernet controller, network interface controller, interface IC, and semiconductor. The DP83934CVUL-25 is identified as a 10 Base-T PHY parallel-interface Ethernet controller. A 10Base-T implementation uses twisted-pair cabling and is suited to legacy 10 Mb/s Ethernet systems, embedded network equipment, network interface adapters, and industrial or commercial control systems that retain compatibility with an existing SONIC-T design. The parallel interface provides a direct connection route to compatible bus and buffer logic rather than relying on a serial transceiver. Key characteristics include a 25 MHz system-oriented design, a 160-PQFP package, and a 4.75 V to 5.25 V supply requirement. Its 140 mA operating supply current is a key design consideration when calculating total system power and thermal behavior. The commercial 0 °C to 70 °C range distinguishes this ordered variant from industrial- or extended-temperature versions. The DP83934 incorporates the functions required by a dedicated Ethernet controller, including network-interface control, frame handling, and twisted-pair connectivity. These functions allow a host processor or embedded controller to communicate through Ethernet while separating medium-access and frame-processing tasks from the system processor. This division can reduce host-side protocol overhead in equipment designed around the DP83934 family. PCB implementation requires careful attention to the 160-pin PQFP footprint, high-density escape routing, ground distribution, and signal integrity. The 28 mm by 28 mm package provides ample routing area compared with a compact QFP, but it still demands a disciplined power and return-path layout. Decoupling should be placed directly across the relevant supply pins, and unused inputs should be handled according to the manufacturer’s pin-description and application guidance. This page combines the documented device identity, electrical envelope, package information, lifecycle status, application guidance, and clearly identified family alternatives. It is intended to help engineers assess whether the obsolete DP83934CVUL-25 remains appropriate for legacy maintenance, original-equipment repair, or a controlled redesign rather than new high-volume networking development.

DP83934CVUL-33

DP83934CVUL-33 - 33MHz 10Base-T Ethernet Controller | TI

The Texas Instruments DP83934CVUL-33 is a 33 MHz SONIC-T systems-oriented network interface controller with an integrated 10Base-T PHY, a parallel host interface, and a 160-pin PQFP package measuring 28 x 28 mm. It operates from a 4.75 V to 5.25 V supply and is identified as a commercial-grade component with an operating range of 0°C to 70°C. An Ethernet network interface controller, or NIC, connects a host processor to a physical network. The DP83934 belongs to the SONIC-T controller family and combines network packet handling with twisted-pair physical-layer connectivity. Its parallel interface makes it suitable for embedded systems and industrial equipment that use a processor bus rather than a serial Ethernet PHY arrangement. The integrated 10Base-T PHY reduces the number of external network-interface components required in a legacy 10 Mb/s design. The principal identifiable features of the DP83934CVUL-33 are its 33 MHz controller clock, 10Base-T network support, parallel interface, 4.75 V to 5.25 V supply range, and 140 mA supply current. The -33 suffix identifies the clock configuration, while CVUL identifies the commercial temperature grade and 160-pin PQFP configuration. The supplied 28 x 28 mm package offers adequate pin density for parallel bus, memory-interface, clock, reset, interrupt, and network-related connections. This controller is based on the SONIC-T systems-oriented architecture, an integrated design that places Ethernet packet processing and twisted-pair interface support in one device. Such integration can simplify board partitioning when an existing system already uses the SONIC register and DMA programming model. Direct replacement is nevertheless more dependent on software and board continuity than package similarity alone: register access, interrupt behavior, DMA behavior, and initialization sequences must be compatible with the host processor and existing firmware. Typical applications include legacy 10Base-T industrial controllers, embedded Ethernet gateways, print servers, terminal servers, set-top equipment, and embedded communication systems designed around a parallel host bus. The DP83934CVUL-33 is most appropriate when an existing platform depends on the SONIC-T programming model and the 10Base-T twisted-pair interface. New designs should also evaluate newer Ethernet controllers or PHYs when 100Base-TX, gigabit Ethernet, or a serial Media Independent Interface is required. For implementation, begin with the manufacturer's pin-description and reference-circuit information, then verify every signal voltage, termination arrangement, and crystal or clock requirement against the board design. The 140 mA supply-current figure and 5 V operating range should be included in the power-budget calculation. Commercial availability, lifecycle status, and long-term sourcing commitments should be confirmed before starting a new production design. This page combines package, electrical, application, cross-reference, and design-placement information in one engineering reference. It also distinguishes genuine same-package alternatives from broader Ethernet-controller alternatives whose interfaces or packages differ, helping designers avoid treating functional similarity as proof of drop-in compatibility.

According to the manufacturer datasheet, the device supports a 32-bit non-multiplexed address and data bus, full-duplex operation, and a twisted-pair network interface. A supply current of 140 mA is listed for the device, while its 4.75 V to 5.25 V operating supply range is centered on a conventional 5 V system rail. The parallel host architecture differentiates the DP83936 from compact Ethernet controllers based on serial or reduced-width interfaces. Parallel address and data paths can provide high throughput for systems processing substantial Ethernet traffic, particularly embedded routers, industrial gateways, telecommunications equipment, and legacy computing platforms. The 160-pin package exposes the extensive address, data, control, interrupt, and network-related signals required by this architecture. Typical applications include embedded Ethernet routers, industrial control gateways, network-interface subsystems, communications equipment, and other 5 V systems using a 16-bit or 32-bit processor bus. The controller can also serve as the Ethernet basis for a platform requiring a dedicated network interface rather than a highly integrated controller with an internal CPU. PCB design requires careful attention to the 160-pin footprint, 5 V power distribution, high-speed parallel routing, and transmission-line behavior on the host bus. Follow the manufacturer’s pin-description table and layout guidance when assigning every signal, especially reset, interrupt, address, data, and twisted-pair connections. This product page organizes the controller’s principal electrical, packaging, and interface characteristics, practical application considerations, verified sourcing links, and design guidance. It also distinguishes the 20 MHz device from other SONIC-T clock options so engineers can assess timing compatibility before approving a replacement.

DP83936AVUL-25

DP83936AVUL-25 - 25MHz Ethernet Controller | Texas Instruments

Texas Instruments DP83936AVUL-25 is a 25 MHz full-duplex SONIC-T Ethernet network interface controller with a twisted-pair interface, supplied in a 160-PQFP package measuring 28 mm by 28 mm. It combines a 32-bit non-multiplexed address and data bus with a 4.75 V to 5.25 V supply range and approximately 140 mA supply current. The suffix identifies the 25 MHz configuration within the DP83936AVUL family. An Ethernet network interface controller, or NIC, connects a computer or embedded system to an Ethernet physical layer. The DP83936AVUL belongs to the SONIC-T family of systems-oriented network interface controllers, combining packet-processing hardware with a parallel host-bus interface and twisted-pair network connectivity. This architecture allows network communication to be implemented in 32-bit and 16-bit systems without relying on a software-driven standard network interface. The principal operating features include a 25 MHz clock configuration, full-duplex operation, a 32-bit non-multiplexed address and data bus, and an integrated twisted-pair interface path. The 4.75 V to 5.25 V operating range is compatible with conventional 5 V digital equipment, while the approximately 140 mA supply current provides a defined basis for power-budget calculations. Its parallel interface gives system designers direct access to the controller's internal descriptor, packet, and buffer resources. The DP83936AVUL family was designed for high-speed 32-bit and 16-bit systems in which deterministic host-bus access and direct Ethernet packet handling are important. The 160-lead package provides a large number of address, data, control, interrupt, network, and power connections, supporting integration with systems that use a non-multiplexed parallel architecture. Its operating frequency is the principal distinction among the DP83936AVUL-20, DP83936AVUL-25, and DP83936AVUL-33 configurations. Typical applications include industrial embedded controllers, data-acquisition equipment, laboratory instruments, print servers, industrial networking equipment, and legacy-compatible embedded systems requiring a parallel-bus Ethernet controller. In these systems, the DP83936AVUL can manage Ethernet packet traffic while the host processor accesses transmit and receive buffers through the parallel bus. The external twisted-pair interface also requires suitable magnetics and network-line implementation in the final design. A key design consideration is that this controller uses a high-pin-count package and a parallel host bus, so routing, termination, decoupling, and signal-integrity planning require more PCB attention than a compact serial-interface Ethernet device. Follow the manufacturer's pin-description and layout guidance in the DP83936AVUL datasheet, place bypass capacitors close to the supply pins, and use a multilayer board with a continuous ground reference when routing the address and data buses. This product record combines the manufacturer's family description, exact operating specifications, package information, source links, application engineering guidance, and a careful assessment of replacement constraints. It also distinguishes the 25 MHz device from frequency variants while avoiding unsupported claims about lifecycle, environmental ratings, and pin-level functions.

It uses a 32-bit non-multiplexed address and data bus and is packaged in a 160-pin PQFP measuring 28 x 28 mm. The controller is designed for 16-bit and 32-bit systems requiring dedicated Ethernet packet-processing and network-interface functionality. A network interface controller, or NIC, is the subsystem that moves framed Ethernet data between a host processor and the physical network layer. The DP83936 belongs to the SONIC-T controller family and combines packet handling, buffer management, bus interfacing, and twisted-pair connectivity. Its parallel bus architecture separates high-throughput host access from the Ethernet medium, allowing systems to use dedicated Ethernet hardware instead of implementing the complete protocol stack in general-purpose logic or software. The DP83936AVUL-33 operates from 4.75 V to 5.25 V and requires approximately 140 mA supply current. It supports 10 Base-T operation through its twisted-pair interface and operates in a commercial temperature range of 0°C to +70°C. The 33 MHz suffix identifies the 33 MHz SONIC-T configuration, while the AVUL suffix identifies the 160-pin PQFP package option used by this ordering code. The controller is designed around a 32-bit non-multiplexed address and data bus, providing distinct address and data paths to the host system. This organization can reduce bus contention compared with a shared multiplexed interface and supports efficient access to the controller's internal packet buffers. Host-side software and hardware must follow the timing requirements and pin definitions in the manufacturer datasheet, particularly for bus-request, hold, and chip-select signaling. Typical applications include embedded industrial Ethernet equipment, embedded computing platforms, network appliances, printer controllers, telecommunications equipment, and other systems that need a dedicated 10 Base-T interface. Because the DP83936AVUL-33 is designed for legacy 10 Base-T networks, a current design should confirm that 10 Base-T remains a requirement before committing to this controller. Systems requiring Fast Ethernet, gigabit Ethernet, or a compact two-wire Ethernet PHY should evaluate a newer Ethernet interface family instead. The principal design consideration is PCB integration. A 160-pin PQFP requires careful escape-routing around all four sides of the device, while the parallel host bus demands short, impedance-conscious routing and complete decoupling of the 5 V supply. The 28 x 28 mm footprint is substantially larger than contemporary leadless Ethernet devices, so board area and assembly requirements should be considered before using an existing SONIC-T board in a new design. This product page consolidates the controller identity, operating limits, package details, comparison parameters, and practical integration considerations from the Texas Instruments datasheet and distributor technical records. It also distinguishes the verified frequency and package variants from broader Ethernet-controller alternatives, helping engineers assess footprint reuse, bus timing, thermal conditions, and legacy-network suitability before committing a board layout.
