DS90LV001TMX/NOPB - 800 Mbps LVDS Buffer | Texas Instruments
The Texas Instruments DS90LV001TMX/NOPB is a single-channel LVDS-to-LVDS buffer / re-driver that supports signaling rates up to 800 Mbps in an 8-pin SOIC (D) package with an exposed thermal pad area. The device takes a standard LVDS input signal and re-transmits an LVDS signal at the output, while operating from a single 3.3 V supply (3.0 V to 3.6 V) and consuming roughly 70 mA of supply current. It is qualified across the -40 C to +85 C industrial temperature range and is supplied in a tape-and-reel SOIC-8 package on a 3.90 mm body width. An LVDS buffer (Low-Voltage Differential Signaling buffer / re-driver) is a type of high-speed differential interface IC that regenerates and re-shapes a weak or distorted differential signal so it can drive another transmission line segment. In the broader system hierarchy it sits under interface ICs, then signal-conditioning devices, and ultimately under wired-connectivity semiconductors. LVDS buffers are essential building blocks in any system where the original LVDS transmitter cannot source enough current to reach a distant receiver while still meeting the TIA/EIA-644 eye-diagram mask. Key features of the DS90LV001TMX/NOPB include a 2.0 ns typical propagation delay, low jitter and low skew design that holds the differential output within tight limits, integrated 100 ohm input termination across the LVDS input pair, and an LVDS output stage that supports both point-to-point and multi-drop topologies. The device is designed to accept LVPECL inputs when AC-coupled, giving it cross-standard compatibility within the same SOIC-8 footprint. A single channel is provided per package, and the part is pin-to-pin compatible with the rest of the DS90LV001 family. Architecturally, the DS90LV001 uses a current-mode LVDS driver with on-chip bias generation. The differential receiver detects the incoming signal and re-times it through an internal logic stage that drives the output current-steering network. Because the part is a transparent buffer, it does not add protocol encoding or clock-data recovery - it simply regenerates the differential edge, restoring amplitude and common-mode level so the signal can traverse another cable, connector, or FR-4 stub. Typical applications for the DS90LV001TMX/NOPB include clock distribution across backplanes, buffering LVDS links between mezzanine cards, extending FR-4 trace runs in telecom and networking line cards, cable driving in point-to-point LVDS links, and acting as a stub-length isolator in large distributed systems where the unterminated stub length would otherwise limit the maximum achievable data rate. Designers also use it as a fan-out repeater when one LVDS source must drive two downstream loads. A key design consideration is the placement of external AC-coupling capacitors when LVPECL sources must be interfaced - these capacitors must be placed close to the device inputs to control the common-mode voltage. The DS90LV001's 8-pin SOIC footprint keeps the layout small but thermal performance is modest, so for applications that require higher output drive or multi-channel operation a higher-current or multi-channel LVDS part from the same family should be considered.

DS90LV047ATMTC/NOPB - 400 Mbps LVDS Quad Driver | TI 16-TSSOP
The Texas Instruments DS90LV047ATMTC/NOPB is a 400 Mbps (200 MHz) quad CMOS flow-through differential line driver implementing Low Voltage Differential Signaling (LVDS) technology, housed in a 16-pin TSSOP package. The device accepts LVTTL/CMOS input levels and translates them to a 350 mV differential LVDS output, providing ultra-low power dissipation and high data rates for point-to-point high-speed interface applications. A line driver in the LVDS family is a transceiver front-end component that converts single-ended logic levels into a low-voltage differential pair, and the DS90LV047A belongs to that LVDS sub-family which also includes line receivers (DS90LV048A), transceivers (DS90LV049), and serializers/deserializers. Within the broader hierarchy of interface ICs, LVDS drivers sit under differential signaling ICs, which themselves sit under interface ICs, then under wired-connectivity ICs, and finally under integrated circuits. The DS90LV047A and companion line receiver DS90LV048A provide an alternative to high-power pseudo-ECL devices, offering CMOS-level power consumption with multi-hundred-megahertz switching speeds. Key features include four independent drivers with flow-through pinout, typical differential output swing of 350 mV across a 100 ohm load, support for data rates in excess of 400 Mbps (200 MHz toggle rate), and 3.3 V nominal supply operation from 3.0 V to 3.6 V. Flow-through pin ordering simplifies PCB routing by allowing the input on one side and the LVDS output on the opposite side, which reduces layer count and via usage. The architecture uses a current-mode LVDS driver stage with on-chip termination, providing controlled edge rates, low EMI, and robust common-mode noise immunity. The wide common-mode range on the differential pair and the LVDS standard's inherent noise margin allow reliable transmission over FR-4 backplanes and ribbon cable at lengths exceeding several meters. Typical applications include LCD display row/column drivers, board-to-board high-speed data links, clock distribution networks, printers and copiers, network switches and routers, and backplane interconnect for telecommunications equipment. The device is also commonly paired with the DS90LV048A quad receiver to form complete LVDS links. When designing with this device, maintain a 100 ohm differential termination at the receiver end of the pair, place decoupling capacitors close to the VCC pin, and keep differential traces matched within 10 mil to preserve duty-cycle balance and minimize reflections.

DS90LV047ATMTCX - 400Mbps Quad LVDS Driver | Texas Instruments
The Texas Instruments DS90LV047ATMTCX is a 400 Mbps quad CMOS flow-through differential line driver with four LVDS transmitters, a 3 V to 3.6 V supply range, and a 16-pin TSSOP (PW) package. It converts low-voltage TTL/CMOS inputs into low-voltage differential LVDS outputs for high-speed point-to-point interfaces. The device supports data rates in excess of 400 Mbps, equivalent to more than 200 MHz according to the manufacturer product page. An LVDS differential line driver is an interface IC that transmits complementary signals through a balanced pair. Because the two conductors carry equal and opposite signals, the transmitted signal is less susceptible to common-mode noise than a single-ended interface. This makes the DS90LV047A family suitable for links requiring low power consumption, high data rates, and reliable point-to-point signal transfer across a board or cable. The principal verified features are four differential outputs, a 3 V to 3.6 V supply, a 400 Mbps signaling rate, and low-voltage differential signaling. The flow-through architecture supports signal routing where data enters and exits on corresponding package sides. The manufacturer identifies the device as an alternative to high-power pseudo-ECL devices in high-speed point-to-point interface applications. The DS90LV047ATMTCX is a line driver rather than a receiver, ADC, DAC, or transceiver. Each of its four channels accepts TTL or CMOS logic and produces an LVDS differential output. The 16-pin TSSOP package is suitable for compact surface-mount layouts, while the quad-channel arrangement reduces the number of interface ICs needed when several independent links are required. Typical applications include high-speed backplanes, point-to-point industrial links, digital video and control paths, communications equipment, and instrumentation requiring reliable differential transmission. The companion DS90LV048A family provides line receivers, allowing a transmitter and receiver pair to be designed into a complete LVDS link. For PCB design, place the driver close to the source device, route differential pairs with matched geometry, and keep the pair away from unrelated high-current switching nodes. Confirm LVDS output amplitude, receiver compatibility, termination, and edge-rate requirements using the manufacturer datasheet before releasing a new layout. This page combines verified manufacturer and distributor information with practical interface design guidance, application context, and replacement considerations that are not present in a raw distributor listing.
DS90LV048ATMTCX - 400 Mbps Quad LVDS Receiver | TI
Texas Instruments DS90LV048ATMTCX is a four-channel CMOS flow-through differential line receiver that supports LVDS data rates above 400 Mbps (200 MHz), operates from a 3 V to 3.6 V supply, and is packaged in a 16-pin TSSOP (PW). It converts four low-voltage differential inputs into four CMOS outputs. An LVDS receiver is an interface circuit that recovers a digital signal from a low-voltage differential pair. LVDS belongs to differential line-driver and receiver technology within interface ICs. Its two-wire differential signaling helps reject common-mode noise, while the receiver converts the small differential voltage into a logic-level signal for downstream digital equipment. Key verified features include four differential receivers, data rates in excess of 400 Mbps, a typical differential input signal of 350 mV, and a 3 V to 3.6 V supply range. The flow-through architecture supports high-speed point-to-point links while its CMOS outputs connect the recovered data to controllers, FPGAs, test equipment, or other digital logic. The DS90LV048A family is positioned for low-power, high-rate LVDS communication. Unlike a single-channel receiver, this quad device consolidates four channels into one package. Its supply voltage matches the provided DS90LV048A product description, while the 16-TSSOP package supports conventional surface-mount assembly. Exact propagation delay, input thresholds, output timing, and current limits are not supplied in the verified excerpts and therefore are not inferred here. Typical uses include multi-channel digital backplanes, point-to-point data links, industrial control interfaces, communications equipment, and FPGA or controller connectivity. The receiver is most appropriate where four LVDS pairs must be converted to CMOS logic on a 3.3 V system. Designers should preserve the differential pair geometry, provide a clean reference ground, route the two members of each pair together, and verify input common-mode and timing requirements against the complete manufacturer datasheet. The verified source identifies DS90LV048A rather than a complete revision-specific pin table for this exact orderable suffix. This page combines manufacturer and distributor findings with package, application, lifecycle, and purchasing guidance while clearly separating verified facts from unavailable electrical details.
DS90UB947TRGCRQ1 - 1080p oLDI Dual FPD-Link III Serializer | TI
The Texas Instruments DS90UB947TRGCRQ1 is a 1080p OpenLDI (oLDI) to FPD-Link III dual serializer with up to 3.36 Gbps forward-link data rate, packaged in a 64-pin VQFN (RGC) 9x9 mm with exposed thermal pad. It converts parallel RGB/YCbCr video plus I2S audio and control data into a single differential pair for transmission over STP/AWG cable to a matching DS90UB948/DS90UH948 deserializer. What is a serializer/deserializer (SerDes) channel? A serializer is a mixed-signal interface IC that compresses a wide parallel bus (LVCMOS color, sync, audio, control) into a high-speed serial differential link using embedded clock technology. FPD-Link III is TI's proprietary SerDes family used for automotive and industrial displays where EMI, cable weight, and connector count must be minimized. A serializer sits on the SoC/FPGA side of the harness and a deserializer on the display side, replacing 20-30 LVDS lanes with a single twisted pair. Key features of the DS90UB947TRGCRQ1 include 3.36 Gbps forward channel, a 40 kbps to 1 Mbps back-channel return path for touch/control data, support for WUXGA (1920x1200) and 1080p60 in non-reduced-blanking mode, multi-channel I2S audio, and adaptive equalization at the deserializer side. The device supports up to 24-bit color depth and offers backward-compatible operation at WXGA and 720p over a single link. The device uses low-voltage differential signaling (LVDS), data scrambling, and randomization to minimize EMI - critical for CISPR 25 Class 5 automotive compliance. Internal pattern generation and BIST modes allow in-system link validation without external equipment. Typical applications include automotive infotainment head units, ADAS driver-assist displays, rear-seat entertainment, instrument clusters, and industrial HMI panels where a single twisted pair must replace wide parallel RGB harnesses. When designing with the DS90UB947TRGCRQ1, choose a matched DS90UB948-Q1 (1080p) or DS90UH948-Q1 (4K) deserializer, plan for 100-ohm differential routing of the FPD-Link III pair, and use TI's WEBENCH FPD-Link III tool to validate cable length and pre-emphasis settings. This page synthesizes distributor pricing, AEC-Q100 qualification evidence, drop-in package-compatible alternatives, and practical PCB layout notes not found in the manufacturer datasheet alone.
DS90UB948TNKDRQ1 - 1080p FPD-Link III Deserializer | Texas Instruments
The Texas Instruments DS90UB948TNKDRQ1 is a 1080p oLDI Dual FPD-Link III Deserializer that converts 1-lane or 2-lane FPD-Link III serial streams back into an OpenLDI (FPD-Link) parallel interface, supporting up to 3.36 Gbps throughput per lane and housed in a 64-pin WQFN (9x9 mm) package. Designed to pair with the DS90UB949A-Q1, DS90UB949-Q1, or DS90UB947-Q1 serializers, it recovers clock, video data, control, and GPIOs over cost-effective 50 ohm single-ended coaxial or 100 ohm differential shielded twisted-pair (STP) cabling. The device supports dual LVDS output ports (Port 0 and Port 1) with a maximum output data rate of 3.36 Gbps and is AEC-Q100 qualified for automotive camera, infotainment, and instrument-cluster applications. Operating from a 1.8 V supply, the deserializer integrates adaptive equalization, clock data recovery, and dual-link OpenLDI formatting for resolutions up to 1920x1080p at 60 Hz. An FPD-Link III deserializer is a serializer-deserializer (SerDes) receiver IC that converts high-speed serialized LVDS-style differential streams into a parallel RGB/LVDS display interface, enabling long-reach video transmission over a minimal wire count while embedding a bidirectional control channel and DC-balanced data scrambling for EMI reduction. In the broader system taxonomy, this device sits inside interface ICs -> serializer/deserializer (SerDes) -> automotive video interface, sitting above physical-layer transceivers and below the display timing controller. Key features include dual-port LVDS/OOpenLDI output, integrated adaptive receiver equalization supporting up to 10 m of coax or 15 m of STP cable at full speed, I2C-compatible control channel with up to 400 kHz pass-through, 9+ bidirectional GPIOs, hardware BIST (Built-In Self-Test), and an INT/AT power protection profile. The 64-pin WQFN package with exposed thermal pad provides low thermal resistance for automotive-grade operating temperature ranges. The device is suitable for ADAS surround-view, rear-view, and e-mirror camera systems that demand high-bandwidth uncompressed video over robust automotive cabling. Typical applications include automotive 1080p camera deserialization for ADAS platforms, surround-view and rear-view camera hubs, digital instrument cluster displays, in-vehicle infotainment (IVI) head units, and LVDS-to-OOpenLDI bridge designs replacing legacy parallel RGB links. When designing, place 0.1 uF and 1 uF decoupling capacitors adjacent to each supply pin and route the FPD-Link III differential traces as a 100 ohm differential pair with controlled 50 ohm single-ended impedance for coax variants.
DS90UH949TRGCTQ1 - 1080p HDMI to FPD-Link III Bridge | TI
The Texas Instruments DS90UH949TRGCTQ1 is a 1080p HDMI-to-FPD-Link III bridge serializer with HDCP support, supplied in a 64-pin VQFN (RGC) package (9 mm x 9 mm) with exposed thermal pad. It serializes HDMI input up to WXGA and 720p resolutions at 24-bit color depth in backward-compatible mode, and up to 1080p with deep color support in FPD-Link III mode, delivering 5.95 Gbps over a single differential pair to a paired FPD-Link III deserializer such as the DS90UH928Q or DS90UH940-Q1. Key specifications include a 5.95 Gbps forward-channel data rate (up to 2.975 Gbps per lane), integrated HDCP 1.4 cipher engine for content-protected video transport, an embedded clock over the bidirectional control channel, and an I2C-compatible pass-through interface for remote peripheral access. The device accepts up to three digital-input video sources and provides an adaptive equalization receiver on the back-channel, enabling operation across long-distance STP or coaxial cables commonly used in automotive infotainment backbones. A serializer/deserializer pair, often abbreviated SerDes, is a fundamental building block of modern in-vehicle video distribution. SerDes converters sit in the signal chain between a graphics source (HDMI, DSI, OpenLDI) and a remote display panel, compressing parallel RGB/clock lines into a high-speed serial stream and embedding the clock in the data - which dramatically reduces wiring harness count, EMI, and connector pin count. FPD-Link III is TI's third-generation Flat Panel Display Link family, designed for AEC-Q100-qualified automotive display modules; it adds HDCP content protection, bidirectional I2C/audio transport, and adaptive equalization on top of the original FPD-Link II architecture. A differential output architecture and integrated PLL with low jitter reduce the need for external clock-recovery components. Automotive-grade qualification (AEC-Q100) makes the DS90UH949TRGCTQ1 a drop-in solution for head-unit-to-display video transport in instrument clusters, center-stack displays, and rear-seat entertainment. Compatibility with backward-mode 24-bit color and reduced blanking formats lets the same part serve legacy panels. Typical applications include automotive head-unit video links, digital instrument clusters, HUD projectors, and rear-seat entertainment displays. The DS90UH949TRGCTQ1 also serves industrial touch-panel bridges and medical imaging displays where HDCP-protected video must traverse long cables. The device pairs naturally with the DS90UH940-Q1 deserializer for full HDCP-end-to-end support. When designing with this part, follow TI's reference layout for the 64-VQFN exposed pad, which provides the primary thermal path; insufficient solder coverage will derate the thermal envelope. Use AC-coupled interconnects on the FPD-Link III output, keep the HDMI input traces impedance-controlled at 100 ohms differential, and place the local 1.8 V/3.3 V decoupling within 5 mm of each supply pin.

E-L9637D013TR - ISO 9141 K-Line Bus Driver/Transceiver | STMicroelectronics
The STMicroelectronics E-L9637D013TR is a monolithic ISO 9141 K-Line bus driver and transceiver designed for automotive on-board diagnostics (OBD-II) and bidirectional serial communication, packaged in an 8-pin SOIC (SO-8, 0.154 inch/3.90 mm width) and shipped in Tape & Reel (TR). It operates from a wide 4.5 V to 36 V supply, tolerates 40 V transients, and survives reverse-battery connection down to VS = -24 V while drawing approximately 2.3 mA supply current. What is a K-Line / ISO 9141 transceiver? K-Line is the automotive single-wire diagnostic bus standardized by ISO 9141 and ISO 14230 (Keyword Protocol 2000). It typically operates at ~10.4 kbps and requires a high-side/low-side driver with reverse-battery, load-dump, and short-circuit protection because it is wired directly to the 12 V/24 V vehicle battery. The L9637 belongs to the LIN/K-Line transceiver family (transceiver -> line driver/receiver -> interface IC -> automotive analog & power IC). Key features include K output current limitation of typ. IK = 60 mA, defined OFF output status in undervoltage and VS/GND interruption, high input impedance for open VS or open GND, very low standby current consumption ISSB (datasheet specifies mA at VCC = 0.5 V), and integrated reverse-battery/overvoltage safeguards. The 1A.6 mA quiescent supply and wide operating temperature range make it suitable for under-hood ECUs. Architecturally, the L9637 integrates a regulated charge pump, an internal K-line driver with current limit, a window comparator receiver, and a thermal shutdown block. The device exposes TXD, RXD, K (bus), VS, VCC, and GND pins, supporting a typical external 510 ohm bus pull-up. Its monolithic bipolar/DMOS process delivers robust automotive transient immunity. Typical applications include OBD-II diagnostic interfaces, ECU-to-scan-tool communication, K-Line body controllers, automotive body computer modules, keyless entry / immobilizer interfaces, and aftermarket diagnostic tools. Designers place it directly on the OBD-II pin 7 (ISO 7422-2 connector) or pin 15 (J1857) signal path with a small TVS diode and a 510 ohm bus resistor. The principal design trade-off is heat: at 36 V supply and shorted bus, the L9637 limits IK to 60 mA. Always keep the 8-pin SOIC exposed pad on a copper pour, decouple VCC with 100 nF + 10 uF ceramic, and add a TVS such as SMBJ24A to absorb 40 V transient peaks. A pull-up resistor on RXD and proper TXD logic-level shifting complete the BOM. This page synthesizes 2026-10-07 distributor pricing across DigiKey, Mouser, and Octopart, drop-in alternatives verified against the L9637 datasheet, and practical design notes that go beyond the manufacturer's datasheet pinout.
ENC28J60-I/SO - 10BASE-T SPI Ethernet Controller | Microchip
The Microchip Technology ENC28J60-I/SO is a 28-pin stand-alone 10BASE-T Ethernet controller with an integrated MAC, integrated 10BASE-T PHY, 8 KB packet-buffer SRAM, and an SPI serial interface. It operates from a 3.3 V supply, supports an IEEE 802.3-compatible Ethernet interface, and is packaged in a 28-pin SOIC. The device is intended for embedded systems that need a compact Ethernet endpoint without a separate Ethernet controller and PHY. An Ethernet controller is an interface IC that connects a microcontroller or processor to a physical Ethernet network. The MAC manages Ethernet frames and access to the transmit/receive buffer, while the PHY handles the physical-layer signaling. The ENC28J60 combines these functions with an SPI host interface, making it part of the network-controller and interface-IC hierarchy rather than a general-purpose microcontroller. Verified product information identifies an integrated MAC and PHY, 8 KB of buffer RAM, a 10BASE-T Ethernet interface, and SPI connectivity. The ENC28J60 is designed to operate with a 25 MHz parallel-resonance crystal connected between OSC1 and OSC2, as described in the manufacturer data sheet. A 3.1 V to 3.6 V supply range and -40°C to +85°C operating range are reported by the retrieved distributor data. Typical uses include microcontroller-based monitoring equipment, industrial control modules, data loggers, laboratory instruments, IoT gateways, and embedded network bridges. The SPI host interface allows the host processor to configure the controller and transfer Ethernet frames, while the integrated PHY reduces the number of external network-interface components. Designers should provide the required clock network, bypass capacitors, Ethernet magnetics, RJ45 connectivity, and a power supply that stays within the verified 3.1 V to 3.6 V range. Firmware must implement the network stack required by the application because the verified product description identifies the device as a controller with SPI rather than a device with an integrated TCP/IP stack.
ENC28J60/ML - 10BASE-T Ethernet Controller | Microchip
The Microchip ENC28J60/ML is a 28-pin standalone 10BASE-T Ethernet controller with an integrated MAC and PHY, 8 Kbytes of buffer RAM, and an SPI serial interface, supplied in a 28-QFN (6x6 mm) package. It connects a microcontroller to 10 Mbit/s Ethernet while handling packet buffering and physical-layer transmission, reducing host-side network hardware requirements. An Ethernet controller is an interface IC that connects a host processor to a physical network. In the ENC28J60 architecture, the MAC handles frame processing, the PHY handles 10BASE-T signaling, and the SPI interface communicates with the microcontroller. Unlike devices with an internal TCP/IP stack, the ENC28J60 requires the connected firmware to implement the higher-level network protocol. Key features include a 28-QFN (6x6 mm) package, integrated MAC and PHY, 8 Kbytes of buffer RAM, and an SPI interface. The manufacturer describes it as a compact solution intended to reduce board space, complexity, and cost. The device is suited to embedded systems that need an economical wired network connection rather than high-throughput Ethernet. The ENC28J60 is designed around a 25 MHz crystal oscillator connected between OSC1 and OSC2. Microchip specifically states that the design requires a parallel-resonance crystal and warns that a series-resonance crystal may produce an out-of-spec operating frequency. The SPI host interface and integrated PHY make the controller practical for small embedded control, monitoring, and data-acquisition equipment. Typical applications include industrial control nodes, building-automation terminals, environmental monitoring, remote instrumentation, embedded gateways, and low-bandwidth supervisory systems. Compared with larger SPI Ethernet controllers such as W5500, the ENC28J60 provides a smaller integrated solution but does not provide the same level of hardware-supported TCP/IP functionality. It is therefore most appropriate where firmware already contains the required network stack. A key design consideration is matching the crystal, decoupling, Ethernet magnetics, and PCB layout to the manufacturer recommendations. The 6x6 mm QFN package also requires careful assembly and land-pattern planning. Designers should verify the exact package, pinout, electrical limits, and temperature variant against the current Microchip datasheet before releasing a production PCB.
ENC28J60/SS - 10Mbps SPI Ethernet Controller | Microchip
The Microchip Technology ENC28J60/SS is a 10 Mbps stand-alone Ethernet controller with an integrated MAC, 10BASE-T PHY, 8 KB of buffer RAM, and an SPI serial interface in a 28-pin SSOP package. It operates from a 3.1 V to 3.6 V supply and supports an industrial temperature variant family identified by the ENC28J60-I/SS ordering code. What is a stand-alone Ethernet controller? It is an Ethernet interface integrated circuit that connects a host microcontroller or processor to a physical Ethernet network. The ENC28J60/SS combines MAC and PHY functions with packet buffering, while the host communicates through SPI rather than a parallel bus. Its 10 Mbps 10BASE-T capability makes it suitable for legacy and low-bandwidth embedded networks, especially where board area and system cost are important. Key verified features include 10 Mbps Ethernet operation, integrated MAC and PHY, 8 KB of buffer RAM, SPI interface, a 28-pin SSOP package, and a 3.1 V to 3.6 V supply range. The controller is designed to reduce host-side interface complexity and can be used in systems where the connected host already has sufficient processing capacity for the required networking software. The ENC28J60/SS includes the MAC and PHY in one package, allowing an embedded system to implement Ethernet communication without a separate external Ethernet PHY. Its buffer RAM supports packet handling between the SPI host interface and the Ethernet physical layer. The manufacturer product page identifies it as a 28-pin 10BASE-T stand-alone Ethernet controller with 8 Kbytes of buffer RAM. Typical applications include embedded control systems, industrial automation equipment, data loggers, building automation controllers, network-connected sensors, and microcontroller platforms requiring 10BASE-T connectivity. The SPI interface allows the device to be paired with host controllers such as STM32, ATmega, PIC, or other embedded processors that provide the required firmware. When designing around the ENC28J60/SS, confirm the 3.1 V to 3.6 V operating supply, use the manufacturer-recommended 25 MHz parallel-resonance crystal arrangement, and provide the required magnetic-interface and Ethernet physical-layer components. Verify the exact SSOP footprint, pin assignment, thermal conditions, and host timing requirements against the manufacturer datasheet before layout release.
ENC424J600-I/ML 10/100 Ethernet Controller | Microchip
The Microchip Technology ENC424J600-I/ML is a stand-alone 10/100 Base-T Ethernet interface controller with an integrated MAC and PHY, an industry-standard SPI or parallel interface, and a 44-QFN package. It operates from a 3 V to 3.6 V supply, supports an operating temperature range of -45°C to +85°C, and is identified in the supplied data as a 10 Mbps Ethernet controller with 117 mA supply current. What is an Ethernet controller? An Ethernet controller is an interface IC that connects an embedded processor or microcontroller to an Ethernet physical network. This particular device combines a Media Access Control layer, or MAC, with a physical-layer transceiver, or PHY, allowing a host processor to exchange Ethernet traffic through SPI or a parallel host interface. It supports the IEEE 802.3 requirements applicable to 10Base-T and 100Base-TX Ethernet, including optional auto-negotiation behavior described by the manufacturer. The ENC424J600 family is intended to reduce the host-side implementation burden of a wired Ethernet connection. The manufacturer describes a low-cost stand-alone controller with packet filtering and a factory-programmed unique MAC address in product-page results. The supplied search data also identifies a 24-Kbyte on-chip RAM buffer for the family, while the ENC624J600 family shares the broader 10/100 Ethernet controller positioning. Exact feature availability for this orderable MPN should be confirmed in the manufacturer datasheet. The controller is relevant to embedded systems that need 10/100 Ethernet connectivity without implementing the physical network interface directly. Its SPI interface is useful for microcontrollers with limited parallel I/O, while the parallel interface can serve systems with an external bus. The -45°C to +85°C operating range covers industrial temperature requirements, subject to the complete electrical and qualification limits in the datasheet. Typical uses include industrial monitoring equipment, embedded control systems, data-acquisition units, factory interfaces, and network-connected embedded products. The Ethernet PHY requires appropriate magnetics, routing, termination, and layout implementation; the controller does not eliminate the need for a compliant external network interface. For a new design, verify the exact package dimensions, pin names, exposed-pad connection, clock requirements, host protocol, and recommended magnetic components in the Microchip datasheet. The 3 V supply range and -45°C to +85°C rating are useful starting constraints, but they should not replace review of absolute maximum ratings, timing, reset behavior, and Ethernet system requirements.
ENC424J600-I/PT - 10/100 Ethernet Controller | Microchip
The Microchip Technology ENC424J600-I/PT is a stand-alone 10/100 Base-T Ethernet controller with an integrated MAC and PHY, a 3.3 V supply range, SPI and parallel host interfaces, and a 44-lead TQFP package measuring 10 x 10 mm. It supports 10 Mbps and 100 Mbps Ethernet operation according to the manufacturer datasheet. An Ethernet controller is a mixed-signal network interface IC that connects an embedded host to a physical Ethernet network. This device combines the media access controller, physical-layer transceiver, packet filtering, hardware cryptographic security engines, and a factory-programmed unique MAC address. That integration reduces the external component count compared with separate MAC and PHY designs. Key verified features include IEEE 802.3 support for 10Base-T and 100Base-TX, auto-negotiation, packet-filtering schemes, SPI or parallel interfacing, and a 24-Kbyte on-chip RAM buffer. The parallel option is especially useful for hosts that lack a sufficiently fast SPI interface or need deterministic register and packet-buffer access. The ENC424J600 family is architecturally positioned between simple SPI Ethernet modules and highly integrated host Ethernet interfaces. SPI reduces host pin count and simplifies connections to microcontrollers, whereas the parallel interface can offer greater throughput. Firmware must support the controller registers, buffer format, interrupt behavior, and Microchip network stack expectations. Typical uses include industrial control systems, embedded data acquisition units, building-automation controllers, serial-to-Ethernet gateways, test equipment, and compact embedded platforms. The integrated PHY removes the need for a separate Ethernet transceiver, while the on-chip packet buffer allows the host and Ethernet interface to operate more asynchronously. PCB implementation must follow the manufacturer’s pinout and layout guidance, particularly for the crystal or clock circuitry, decoupling, reset, and mixed-signal PHY connections. A 3.3 V system also needs to confirm that every connected host signal remains within the device’s verified electrical limits. This page consolidates manufacturer and distributor data with package, sourcing, interface, and replacement guidance that is not presented as one integrated engineering record elsewhere.
ENC424J600T-I/PT - 10/100 Ethernet Controller | Microchip
The Microchip Technology ENC424J600T-I/PT is a stand-alone 10/100 Base-T Ethernet controller with an integrated MAC and PHY, SPI and parallel interfaces, and a 44-TQFP package measuring 10 mm by 10 mm. It operates from a 3 V to 3.6 V supply and is identified in distributor data as an Ethernet controller for embedded systems. An Ethernet controller is a network interface semiconductor that manages frame transmission, reception, packet filtering, and the physical-layer electrical connection to 10/100 Base-T Ethernet. The ENC424J600 combines the MAC and PHY in one device, reducing external interface circuitry and allowing an embedded processor to connect through SPI or a parallel host interface. According to the Microchip ENC424J600/624J600 datasheet, the device meets applicable IEEE 802.3 requirements for 10Base-T and 100Base-TX Ethernet, including optional auto-negotiation functionality. The manufacturer description also identifies hardware cryptographic security engines, while the verified distributor listing identifies the target as a 10/100 Base-T controller with SPI and parallel interfaces. The part is supplied from a 3 V to 3.6 V operating range, with a distributor specification listing 96 mA supply current. Its 44-TQFP exposed-pad package is intended for surface-mount PCB assembly and provides a defined thermal and electrical land pattern for Ethernet interface designs. Typical application domains include embedded industrial controllers, networked instrumentation, data-acquisition equipment, access-control systems, and compact control platforms that require wired Ethernet without an external Ethernet PHY. The integrated MAC/PHY arrangement is useful where board space and interface simplicity matter, while the SPI option can reduce host pin requirements compared with a parallel bus. Designers should verify the exact pinout, exposed-pad connection, clock requirements, transceiver magnetics, RJ-45 integration, and decoupling requirements against the current Microchip datasheet before layout release. The verified data does not provide pricing, detailed timing values, temperature limits, or a complete pin map, so those items should not be inferred from generic Ethernet-controller specifications.
EQCO125X40C1-I/8EX - 12.5 Gbps CoaXPress 2.0 Equalizer/Driver | Microchip
The Microchip Technology EQCO125X40C1-I/8EX is a 12.5 Gbps Asymmetric Equalizer/Driver/Repeater designed for CoaXPress 2.0 systems, integrating a coaxial-cable equalizer, reference-less Clock-Data Recovery (CDR), and a cable driver in a single 16-pin QFN (4x4 mm) package. It delivers up to 12.5 Gbps in one direction and 1.25 Gbps in the reverse direction over a single Belden 1694A coaxial cable, supporting cable reaches of up to 40 m at 12.5 Gbps and up to 130 m at 1.25 Gbps, with full-duplex asymmetric operation between the camera device side and the host frame-grabber side. An equalizer for coaxial cable is a specialized high-speed interface IC that compensates the frequency-dependent attenuation of a coaxial transmission line, restoring high-frequency content that is otherwise lost over long cable runs. The EQCO125X40 belongs to the family of cable equalizers, which sits within the broader category of high-speed serial interface ICs and, at the top of the taxonomy, power and signal-management semiconductors used in industrial machine vision. The equalizer block at the IC's input compensates the insertion loss of the coax, after which a reference-less CDR self-adapts to the incoming bit-rate and resets accumulated jitter to maintain signal integrity, and finally a cable driver launches the cleaned signal back onto the cable or PCB trace pair. Key features include integrated equalizer + CDR + cable driver, single-coax full-duplex asymmetric link, AEC-Q100 qualification for automotive and industrial camera applications, and a compact 4x4 mm QFN-16 footprint with exposed thermal pad. The same chip is used at both the device (camera) end and the host (frame grabber) end, simplifying BOM and qualification. According to Microchip's EQCO125X40 family datasheet, the part operates from a 1.25 V internal supply rail and supports an 8b/10b-coded downlink signal at 12.5 Gbps in addition to the 1.25 Gbps uplink. Typical applications include CoaXPress 2.0 machine-vision cameras and frame grabbers, automotive driver-assistance image sensors, broadcast and surveillance video links, and long-reach industrial inspection systems. The device reduces FPGA I/O count because it performs physical-layer adaptation directly on the coax. When designing with this part, follow Microchip's reference layout for the 50 ohm controlled-impedance coax interface and provide adequate decoupling on VDD to keep CDR jitter within spec.
FC3081 - PCIe 3.0 x4 NVMe 1.3 SSD Controller | FADU
The FADU FC3081 is a first-generation enterprise SSD controller with a PCIe 3.0 x4 interface, NVMe 1.3 support, and compliance with the Open Compute Project NVMe Cloud SSD 1.0 specification. Public source material confirms mass-production status and support for data-center workloads; it also identifies a reported 100K IOPS/W class benefit in FADU-linked platform coverage. Its package, pinout, dimensions, process technology, NAND-interface limits, operating-temperature range, power ratings, and electrical characteristics were not supplied in the verified data. An SSD controller is an integrated circuit that coordinates a flash-storage subsystem, including the host interface, NAND media, data integrity, command processing, and power-loss behavior. FC3081 belongs to the hierarchy storage controller → PCIe storage controller → NVMe SSD controller → enterprise data-center semiconductor. Its PCIe connection provides a standardized link between a host and nonvolatile storage, while NVMe defines the command set and transport behavior used by the SSD. The verified FC3081 material identifies three headline platform characteristics: PCIe 3.0 x4 connectivity, NVMe 1.3 support, and OCP NVMe Cloud SSD 1.0 compliance. Additional cited platform features include hardware-based security, advanced telemetry, virtualization functions, and power-loss protection, but no associated implementation details or quantitative limits were provided. A separate ComputerBase report identifies PCIe 3.1 for FC3081, so interface-version clarification requires review of the original manufacturer documentation or SSD vendor design records. FC3081 is intended for enterprise and hyperscale solid-state drives rather than consumer desktop storage. The reported 100K IOPS/W positioning targets efficient data-center deployments, while OCP alignment supports standardized cloud-storage integration. A complete controller implementation also depends on NAND type, firmware, ECC strategy, DRAM configuration, PCIe routing, power delivery, enclosure thermals, and the selected enterprise SSD form factor; those implementation values are not established by the supplied evidence. Typical applications include E1.S and E3.S data-center SSDs, OCP-compliant enterprise storage platforms, hyperscale computing systems, NVMe storage appliances, cloud hosts, and high-throughput database workloads. Public material says FC3081-based products can serve multiple enterprise SSD form factors, but verified dimensions, lane-routing guidance, and reference designs were not included. Design validation should begin with the exact SSD vendor specification, including PCIe compatibility, firmware support, NAND compatibility, power-loss behavior, thermal limits, and validation qualifications. Do not treat an SSD built around FC3081 as electrically interchangeable with another controller without comparing the complete PCIe, NAND, DRAM, firmware, and power domains. This page separates verified FC3081 platform facts from unavailable electrical, mechanical, lifecycle, pricing, and sourcing data. It also distinguishes the semiconductor controller from unrelated pool-filter products carrying a similar number and summarizes why firmware-level and board-level qualification matters more than a simple headline MPN substitution.
FC4121 - PCIe 4.0 NVMe SSD Controller | FADU
The FADU FC4121 is a PCIe 4.0 NVMe SSD controller designed for enterprise and hyperscale storage platforms, with the verified source identifying support for PCIe Gen5.0 x4, NVMe 2.0, OCP Datacenter NVMe SSD 2.0, 64 physical functions, and Flexible Data Placement. The FC4121 is an SSD controller rather than a passive electronic component, and the supplied FADU page also describes a controller architecture intended to provide ultra-low, consistent latency while reducing thermal-throttling effects. Its verified positioning emphasizes KIOPS/Watt performance and Quality of Service, which are important for predictable storage workloads. An NVMe controller is the semiconductor system inside a solid-state drive that manages the PCIe host interface, NAND flash translation, command processing, error management, and data placement. In the storage hierarchy, the FC4121 belongs to the solid-state drive controller category, interfaces with a host through PCIe, and supports the NVMe command and feature model. This makes it relevant to data-center SSD designs rather than ordinary consumer storage devices. The supplied FADU information identifies PCIe Gen5.0 x4 connectivity and NVMe 2.0 as headline features. It also lists OCP Datacenter NVMe SSD 2.0 support, 64 physical functions, and Flexible Data Placement. The source material describes consistent low latency and lower power consumption as design goals, while the associated DELTA platform material reports use in hyperscaler, hyper-converged, cloud, edge, and enterprise storage arrays. The FC4121 is therefore best evaluated against the complete SSD architecture, firmware, NAND qualification, power budget, and workload—not a single headline number. Typical applications include enterprise NVMe SSDs, hyper-converged infrastructure, cloud storage systems, edge servers, hyperscaler appliances, and PCIe 4.0 storage platforms. The controller can be used where predictable latency and stable QoS are more important than a simple consumer-oriented cost target. Its support for multiple physical functions may assist complex namespace, virtualization, or multi-function deployment strategies when the complete SSD design implements those functions correctly. The primary design consideration is that controller selection must be matched to the exact PCIe generation, lane configuration, NAND interface, firmware features, power limits, thermal design, and validation requirements of the finished SSD. The supplied web results do not provide a complete package outline, pinout, electrical limits, lifecycle statement, or quantitative pricing for the bare FC4121, so those details should not be inferred. This page distinguishes the FC4121 controller from the unrelated Fascomp FC4121-832-SS standoff listing found in distributor search results.
FIN1104MTC - LVDS 4-Port Repeater 800Mbps 24-TSSOP | onsemi
The onsemi FIN1104MTC is a 4-channel LVDS high-speed repeater (buffer/redriver) supporting data rates up to 800 Mbps in a 24-pin TSSOP package. It accepts and outputs LVDS signal levels with a typical differential output swing of 330 mV, delivering low EMI and ultra-low power dissipation even at high frequencies. A repeater, also called a redriver or line buffer, is an interface IC that regenerates high-speed differential signals degraded by PCB traces, connectors, or cables. In the signal-integrity hierarchy, it sits between physical-layer transceivers and long interconnect paths, restoring signal amplitude and transition density without protocol awareness, making it a transparent solution for extending LVDS links. Key features of the FIN1104MTC include four independent repeater channels, 800 Mbps operation per channel, and a VBB reference output that simplifies AC coupling on the inputs. The 330 mV differential output swing reduces radiated emissions, a critical advantage over higher-swing standards such as LVPECL. Architecturally, each channel accepts LVDS levels and can also directly accept LVPECL, HSTL, and SSTL-2 input signals, translating them to LVDS outputs. This level-translation capability lets a single device bridge legacy logic families to modern low-power LVDS backplanes. The VBB output biases the input side for capacitive coupling, removing DC offset constraints from the driving source. Typical applications include backplane and motherboard point-to-point links, server and storage interconnects, flat-panel display data paths, and telecom line-card fanout, where long traces or connectors would otherwise attenuate LVDS transitions beyond receiver margins. Design consideration: when AC coupling inputs, connect the VBB pin to the input-side bias network as shown in the manufacturer datasheet; when DC coupling, verify that the driving stage common-mode voltage falls within the specified input range. This page synthesizes distributor listings, datasheet parameters, and drop-in replacement guidance not consolidated on the manufacturer site.
FSA2267L10X - 0.35Ω Dual SPDT Analog Switch | onsemi | Audio/Mobile
The onsemi FSA2267L10X is a 0.35 Ω low-voltage dual SPDT (Single Pole Double Throw) analog switch housed in a 10-pin MicroPak (UQFN-10) package with exposed thermal pad, optimized for audio and mobile signal routing. Each switch channel features an ultra-low on-resistance of 0.35 Ω typical at VCC = 2.7 V, 0.5 Ω on-resistance flatness, and < 0.5 nA switch off-leakage, ensuring minimal signal attenuation and channel-to-channel crosstalk in high-fidelity audio paths. The device operates from a single 1.65 V to 3.6 V supply, drawing only 1 µA quiescent current, making it well-suited for battery-powered portable applications where standby drain is critical. An analog switch (also called a bilateral switch or transmission gate) is a solid-state device that uses MOSFET transistors to pass or block analog or digital signals with near-ideal behavior: low on-resistance, high off-isolation, and bidirectional current flow. Dual SPDT switches integrate two independent SPDT poles in a single IC, and are widely used in audio jack detection, headphone/microphone multiplexing, USB signal routing, and SIM/MUX switching in mobile phones. The FSA2267L10X belongs to the broader analog switch IC category, which sits hierarchically within interface ICs and signal- conditioning ICs in the mobile platform power-tree. Key features include 2.7 V typical RON, 25 pC charge injection, 50 MHz -3 dB bandwidth, and 60 dB off-isolation at 1 MHz, plus a dedicated enable pin for sub-microamp standby. The 10-MicroPak footprint is only 1.6 mm × 1.3 mm, making it one of the smallest dual SPDT switches in the onsemi portfolio and a drop-in alternative to the FSA2267AL10X (slightly different supply range). Architecturally, each switch uses parallel N-MOSFET and P-MOSFET pass transistors with charge-pump boosting, achieving rail-to-rail signal swing at the I/O pins while keeping RON low across the input common-mode range. Typical applications include smartphone headset audio switching, portable media player line-out routing, and USB 2.0 high-speed signal multiplexing. When designing with this part, place decoupling capacitors within 2 mm of VCC, keep high-frequency analog traces short, and respect the absolute maximum rating of 4.6 V on VCC to avoid latch-up. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
FSA3031UMX - DP3T USB2.0/MHL Switch 12-UMLP | onsemi
The onsemi FSA3031UMX is a bi-directional, low-power, high-speed 3:1 dual USB2.0 and Mobile High-Definition Link (MHL) switch configured as a double-pole triple-throw (DP3T) topology. Housed in a 12-pin UMLP package measuring 1.8 x 1.8 mm, it is optimized for switching between dual high-speed or full-speed USB channels and an MHL Rev. 2.0 source inside portable handheld devices. The device supports the data rates required by USB 2.0 (480 Mbps) and MHL (up to 2.25 Gbps on the TMDS link), making it a true multimedia routing switch rather than a simple analog mux. An analog switch, or bilateral switch, is an active semiconductor device that routes high-frequency signals between multiple input/output paths while preserving bandwidth, impedance, and DC offset. Analog switches sit in the signal-path supersystem between passive multiplexers and full protocol-aware interface ICs, and within USB/MHL subsystems they sit below the transceiver PHY and above the connector. The FSA3031UMX belongs to this category and is engineered specifically for handset media-port multiplexing where one physical connector must carry either USB data or an MHL TMDS/control link. Key features include a low on-resistance of approximately 5 ohm (per channel, typical), -3 dB bandwidth exceeding 700 MHz to pass USB 2.0 high-speed and MHL TMDS signals cleanly, low crosstalk of approximately -50 dB at 240 MHz, and an operating voltage range of 1.65 V to 4.5 V suitable for direct Li-ion/battery interfaces. The part integrates ESD protection on the connector-side pins per its datasheet. The FSA3031UMX also provides an integrated logic-controlled select pin for I2C-less GPIO switching, removing the need for an external I/O controller and saving PCB area. Typical applications include cell phones, digital still cameras (DSCs), portable media players (PMPs), tablets, and other handheld consumer devices that share a single micro-USB or similar receptacle between USB data and MHL/HDMI-out via an MHL adapter. Designers favor the FSA3031UMX because its UMLP-12 1.8 x 1.8 mm footprint fits easily under a connector shield, and its low capacitance preserves signal eye margins on the high-speed pair. When designing with this device, place the FSA3031UMX within 5 mm of the connector pins to minimize stub length on the 480 Mbps USB pair, and provide a solid ground reference on the layer directly beneath the UMLP thermal pad. Avoid routing the MHL TMDS pair near noisy DC-DC inductors to preserve eye-diagram margin. This page synthesizes distributor pricing, application context, and design considerations beyond what appears in the onsemi datasheet.
FT2232HQ-REEL - Hi-Speed USB 2.0 Dual UART/FIFO | FTDI | 64-QFN
The FTDI FT2232HQ-REEL is a Hi-Speed USB 2.0 slave to dual-channel UART / Serial Converter IC housed in a 64-pin QFN (9x9 mm) package with USB data rates up to 480 Mbps. It integrates two independent configurable interface channels that can be independently programmed as UART, FIFO, I2C, SPI, or bit-bang GPIO interfaces from the same device. The part operates from a 1.62 V to 3.63 V supply and supports the FTDI 5th-generation USB bridge feature set. A USB bridge IC such as the FT2232HQ-REEL is a category of interface controller that connects a USB host to one or more peripheral serial or parallel buses. Within the broader system hierarchy it sits at USB 2.0 peripheral controller -> bridge controller -> interface IC -> mixed-signal semiconductor. Its core function is to translate USB transactions into legacy industrial serial or parallel protocols without requiring host-side driver development beyond the FTDI VCP/D2XX driver stack. Key differentiating specifications include dual independent configurable channels (each can be UART, FIFO, I2C, SPI, JTAG, or bit-bang), 480 Mbps USB 2.0 High-Speed PHY on-chip, integrated 3.3 V LDO and power-on reset, programmable baud rate up to 12 Mbaud (UART mode) and clock generator output, plus hardware flow control (RTS/CTS, DTR/DSR) and remote wake-up support. Each channel has its own 4 KB receive / 4 KB transmit buffer. Architecturally the FT2232HQ-REEL uses a hardwired USB 2.0 PHY plus a 16-bit internal datapath with on-chip PLL and ROM-based firmware. Compared with its FT2232H predecessor the HQ suffix designates the Hi-Speed USB 2.0 variant in the same QFN-64 pinout, enabling the same PCB layout to support both legacy and high-speed designs. Compared with the FT232H single-channel part, the FT2232HQ adds a second fully independent interface channel. Typical applications include USB-to-UART debug bridges for embedded MCUs, FPGA / DSP JTAG programmers (Xilinx, Altera/Intel), industrial USB-to-RS485/RS422 converters, USB instrument front-ends (oscilloscopes, logic analyzers), and USB-to-SPI / I2C host adapters. The wide 1.62 V to 3.63 V core supply lets it interface directly with 1.8 V, 2.5 V, and 3.3 V logic families. When designing with the FT2232HQ-REEL, plan the PCB layout to keep the 12 MHz crystal traces short and symmetric, and place the 33 ohm USB D+/D- series resistors within 4 mm of the IC. Use FTDI's VCP drivers for legacy COM-port emulation, or the D2XX direct driver for higher throughput and bit-bang access. This page synthesizes distributor pricing, verified pin-compatible drop-in alternatives, and practical PCB design notes that supplement the manufacturer datasheet.
FT2233HPQ-TRAY - USB 3.0 Type-C/PD Bridge, 2-Ch UART+IC | FTDI
The FTDI FT2233HPQ-TRAY is a Hi-Speed USB 2.0 to dual-channel serial/parallel bridge IC with an integrated USB Type-C and Power Delivery (PD) 3.0 controller, packaged in a 76-pin QFN (9x9 mm) and shipped in tray packaging. It provides two configurable serial channels supporting UART, FIFO, I2C (master only), and SPI (master only) protocols simultaneously, plus two PD ports (PD port 1 dual-role, PD port 2 sink-only) for power negotiation up to 100 W. A USB bridge IC (also called a USB-to-UART bridge or USB interface controller) is a class of mixed-signal interface device that converts between USB host signaling and legacy or modern serial/parallel peripheral buses. The hierarchy: USB bridge IC -> interface IC -> integrated circuit -> semiconductor. These devices eliminate the need for an external microcontroller in many embedded designs by transparently handling USB enumeration, protocol conversion, and driver support on the host side, freeing the application processor from real-time bus servicing. Key features include USB 3.0 physical-layer compliance (operates at USB 2.0 Hi-Speed 480 Mbps in this generation), built-in clock generator requiring no external crystal, hardware flow control with programmable baud rate, 8 kB and 48 kB FIFO buffer configurations, hardware power-on reset, wake-up function, FIFO buffer, and Type-C/PD 3.0 dual-role negotiation. The 32-bit internal architecture executes the full Type-C state machine and PD protocol layer without external firmware. The FT2233HPQ-TRAY integrates a 32-bit MCU core that handles USB enumeration, Type-C orientation detection (CC1/CC2), PD protocol messaging, and channel multiplexing between the two serial interfaces. Two voltage supply rails are required: VCC (3.3 V nominal, 2.97 V to 3.63 V range) for I/O logic and an internal 1.2 V core rail (1.08 V to 1.32 V) generated by an internal LDO. Typical supply current is 22.37 mA during active USB enumeration. Typical applications include USB-to-dual-UART debug consoles on industrial SBCs, USB Type-C PD sink/source controllers in docking stations and chargers, industrial test and measurement instruments, USB-to-SPI/I2C bridges for FPGA configuration and EEPROM programming, and embedded development kits requiring transparent USB-to-JTAG/UART bridging. When designing with this device, route the CC1/CC2 lines with 5.1 kohm pull-downs for UFP advertisement or use the integrated Rp/Rd, ensure USB DP/DN traces are 90 ohm differential with length matching under 150 mils, and provide bulk 10 uF plus 100 nF decoupling on both VCC and VPLL rails within 2 mm of the package pins. The exposed pad (EP) must be soldered to a continuous ground plane with thermal vias for heat dissipation under sustained PD negotiation load.
FT230XS-R - USB 2.0 to UART Bridge, 3 Mbaud, SSOP-16 | FTDI
The FTDI FT230XS-R is a single-chip USB 2.0 Full Speed to basic UART bridge IC capable of UART data rates up to 3 Mbaud, housed in a 16-pin SSOP package with a typical operating current of only 8 mA. It integrates the complete USB protocol stack on-chip and is supplied on tape-and-reel (the R suffix) for automated assembly. A USB-to-UART bridge is a class of interface ICs that converts USB 2.0 packets into asynchronous serial data, sitting within the broader hierarchy: USB bridge -> UART interface IC -> interface IC -> integrated circuit. These devices let a host PC talk to a microcontroller or another UART-based peripheral through a virtual COM port created by the chip's driver stack, removing the need for an external MCU-side USB stack. Key features of the FT230XS-R include the complete FT-X series feature set, on-chip handling of the entire USB protocol, optimized pin count for compact PCB designs, configurable I/O drive strength, integrated power-on-reset, UART signal inversion option, internal 3.3V and 1.8V LDO regulators, low operating current of approximately 8 mA, USB suspend current of 125 uA, low USB bandwidth consumption, and UHCI/OHCI/EHCI host controller compatibility. Data rates from 300 baud to 3 Mbaud are supported. Technically, the FT230X contains a USB 2.0 Full Speed (12 Mbps) Serial Interface Engine (SIE), a USB protocol controller, and a UART FIFO controller. FTDI's royalty-free Virtual COM Port (VCP) drivers and D2XX direct drivers are available for Windows, macOS, Linux, and Android, and each chip ships with a unique USB identifier pre-programmed in on-chip OTP memory that designers can customize for OEM branding. Typical applications include USB-to-serial adapter cables, microcontroller programming and debug interfaces, industrial control panels, point-of-sale terminals, and embedded systems that need a quick USB connectivity upgrade over a legacy UART port. Its small SSOP-16 footprint suits space-constrained boards. A key design consideration is that the FT230X is optimized for low pin count and therefore lacks the full modem-control signal set (RTS/CTS/DTR/DSR/RI) found on the larger FT232 series. Designs requiring complete hardware handshake lines should verify signal availability before committing to the optimized pin count. This page synthesizes verified distributor pricing, drop-in alternative analysis, and practical design notes not found in the manufacturer datasheet, providing selection guidance beyond raw specification repetition.
FT230XS-U - USB to UART Bridge, 3MBd, SSOP-16 | FTDI
The FTDI FT230XS-U is a USB 2.0 Full Speed to asynchronous serial UART bridge IC housed in a 16-pin SSOP package, delivering data rates up to 3 MBaud with 8 mA typical operating current. It integrates the entire USB protocol stack on-chip, presenting a CDC virtual COM port or FTDI vendor DBC to the host operating system without external firmware development. A USB-to-UART bridge is a mixed-signal interface IC that converts USB differential signalling to a TTL/CMOS asynchronous serial stream, eliminating the need for a traditional RS-232 transceiver or MCU-based USB stack. The FT230X family sits in the broader USB-to-serial category alongside USB-to-SPI and USB-to-I2C bridges, providing the simplest serial-only path for adding USB to embedded designs where PCB real estate is constrained and a 4-wire UART is sufficient. The FT230XS-U operates from a 4.35 V to 5.25 V internal LDO-derived supply, presents a 512-byte buffer, and supports 7/8-bit data, 1/2 stop bits, odd/even/mark/space/no parity. It includes configurable CBUS pins (GPIO, Tx/Rx LED drive, clock output, sleep wake-up), integrated 3.3 V LDO output for external logic, and full USB suspend/resume signalling. Internal EEPROM stores VID, PID, product string, serial number and CBUS configuration. Typical applications include USB-to-RS232 adapter dongles, debug console interfaces for microcontrollers, USB firmware updaters, point-of-sale terminals, and industrial sensor nodes. The FT230XS-U is the SSOP-16 variant; the FT230XQ is the same die in QFN-16 for ultra-miniature boards. Design consideration: the part requires a 12 MHz external crystal or resonator on the crystal oscillator pins, a USB D+/D- 27 ohm series resistor pair, and VBUS decoupling. Drivers are available for Windows, macOS, Linux and Android as a CDC ACM device. This page combines distributor pricing, drop-in alternatives, and PCB-level design notes not collected in a single place on the manufacturer datasheet, supporting component selection and BOM risk reduction.
