DP83936AVUL-33 - 33MHz Ethernet Controller | Texas Instruments
Teilenummer: DP83936AVUL-33 ✗ AbgekündigtDP83936AVUL-33 Übersicht
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.

Typische Anwendungen
DP83936AVUL-33 ist geeignet für 6 Anwendungs: Embedded Industrial Ethernet Controller, Network Printer Controller, Telecommunications Network Equipment, Embedded Network Appliance, Test and Measurement Instrument, Legacy 10BASE-T Network Interface.
Embedded Industrial Ethernet Controller
The DP83936AVUL-33 fits legacy embedded industrial equipment that must terminate a 10 Base-T twisted-pair network while a host processor handles supervisory logic. Its 32-bit non-multiplexed address and data bus provides separate paths for host addressing and packet data, while the 4.75 V to 5.25 V supply range suits conventional 5 V equipment. The 140 mA listed supply current should be included in the system power budget. Because the package is a large 28 x 28 mm PQFP, it is most practical when an existing SONIC-T layout is being retained or the board has adequate routing area.
Empfohlen
Network Printer Controller
A network printer or multifunction office device can use the DP83936AVUL-33 as a dedicated 10 Base-T interface, allowing the main processor to focus on rendering and document handling instead of executing every Ethernet framing operation. The controller's full-duplex SONIC-T architecture and dedicated twisted-pair interface support sustained network connectivity in systems built around a 32-bit bus. The commercial 0°C to +70°C range fits typical indoor office equipment. Engineering validation must still cover print-job throughput, host-bus latency, and recovery from network or physical-layer faults.
Empfohlen
Telecommunications Network Equipment
The DP83936AVUL-33 is applicable to legacy telecommunications equipment that requires a parallel host processor interface and 10 Base-T connectivity rather than a compact packet-oriented Ethernet interface. The 5 V operating range and dedicated SONIC-T processing architecture support systems designed around 16-bit or 32-bit processors. Its 160-pin PQFP footprint permits use in established boards with adequate component spacing. For new telecom products, evaluate the environmental, isolation, surge, and regulatory requirements alongside the controller's electrical capabilities, and verify long-term sourcing because the device is obsolete.
Empfohlen
Embedded Network Appliance
The controller can provide the Ethernet data path in an embedded appliance whose processor communicates through a high-bandwidth parallel bus. At 33 MHz, DP83936AVUL-33 is appropriate for established SONIC-T systems where the host interface timing and firmware were designed around this operating point. The 32-bit non-multiplexed bus can support sustained packet traffic without sharing address and data lines. Because only 10 Base-T is specified, an appliance requiring contemporary higher-speed links should use a newer Ethernet controller instead of limiting the product specification around this legacy device.
Empfohlen
Test and Measurement Instrument
A legacy test or measurement instrument can use the DP83936AVUL-33 to connect an embedded controller, remote service interface, or data acquisition platform to a 10 Base-T network. The dedicated SONIC-T architecture reduces the host processor's packet-handling burden and provides a defined parallel bus interface. The 4.75 V to 5.25 V supply range integrates with conventional laboratory and industrial electronics. Layout work should provide controlled return paths and decoupling, while system validation should exercise sustained transfers, reset behavior, interrupt handling, and network cable insertion or removal.
Empfohlen
Legacy 10BASE-T Network Interface
The DP83936AVUL-33 is best suited to maintaining a 10BASE-T connection in an established embedded system whose board architecture was designed around the SONIC-T controller and its parallel bus. The integrated twisted-pair interface role avoids treating the controller as a modern multi-gigabit MAC, while the dedicated 33 MHz configuration preserves compatibility with the target platform. Retrofitting it into a compact new PCB is less attractive because the 160-pin PQFP occupies 28 x 28 mm and demands escape routing on all four sides. Use it primarily for targeted repair, legacy product continuation, or verified board reuse.

Wichtigste Unterscheidungsmerkmale
- Higher SONIC-T clock within the same frequency family (vs. DP83936AVUL-25)
- Directly identified SONIC-T replacement path (vs. DP83934CVUL-33)
- Legacy 10BASE-T integration with a parallel host bus (vs. DP83936AVUL-25)
Designhinweise
Route the 32-bit non-multiplexed address and data buses as short, continuous paths between the controller and host processor. Apply the Texas Instruments timing tables for chip select, bus request, hold, read, and write signals rather than relying on general-purpose FPGA timing. Place decoupling capacitors close to the 5 V and ground pins, and provide a low-impedance ground plane. Confirm the exact land pattern for the 28 x 28 mm PQFP before releasing artwork.
Budget approximately 140 mA for the DP83936AVUL-33's listed supply current and design the 5 V rail for a minimum operating range of 4.75 V to 5.25 V. Place input and bulk capacitance close to the package and separate sensitive Ethernet and clock routing from switching-supply paths. Because this is an obsolete legacy controller, verify the power requirements against the exact Texas Instruments datasheet revision and the conditions used by the original system design.
Do not treat a shared 160-pin package outline as proof that another network controller is a drop-in replacement. The bus architecture, buffer organization, reset behavior, interrupt outputs, pin multiplexing, and timing can differ even when the lead count matches. DP83934CVUL-33 therefore requires a manufacturer cross-reference and board-level validation. For DP83936AVUL-25, verify that 25 MHz operation meets throughput and timing requirements before substitution.
The DP83936AVUL-33 is specified for a 0°C to +70°C commercial ambient range. Use the manufacturer's AC and DC electrical limits, package information, and system thermal measurements to determine whether the PQFP requires additional copper or airflow. Do not apply thermal data from a different PQFP variant. In a sealed industrial enclosure, include controller dissipation, regulator loss, and neighboring heat sources when estimating the maximum internal temperature.
Compliance-Informationen
The component record identifies a commercial-temperature 0°C to +70°C network interface controller but does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is treated as not applicable because the device is an Ethernet controller rather than an automotive-qualified component.
