KSZ9031RNXUB-VAO - Gigabit Ethernet Transceiver, AEC-Q100, WQFN-48 | Microchip
The Microchip Technology KSZ9031RNXUB-VAO is a completely integrated triple-speed (10Base-T/100Base-TX/1000Base-T) Gigabit Ethernet physical-layer transceiver for transmission and reception of data on standard CAT-5 unshielded twisted-pair (UTP) cable, housed in a 48-pin lead-free WQFN (7x7 mm) package. The device features an RGMII MAC interface, supports 10/100/1000 Mbps operation, and carries AEC-Q100 qualification for automotive applications. On-chip termination resistors, baseline wander correction, and adaptive equalization simplify PCB design and reduce external BOM. A Gigabit Ethernet transceiver (PHY) is a physical-layer device that converts between the digital MAC-side interface (here, RGMII) and the analog line-side signaling on copper twisted-pair cable. It sits between an Ethernet MAC (typically inside an SoC, FPGA, or Ethernet switch) and the RJ45 magnetics/MDI connector, and is the cornerstone of any 1000Base-T link. The KSZ9031 belongs to the broader Ethernet PHY hierarchy: Ethernet transceiver -> physical layer device (PHY) -> network interface IC -> wired networking semiconductor. Key features include a 125 MHz reference clock output, energy-detect power-down for reduced power when no cable is attached, Wake-on-LAN (WOL) support with robust custom-packet detection, programmable LED outputs for link/activity/speed indication, and remote and local loopback for verifying analog and digital data paths. The standard KSZ9031RNX is offered in 48-pin QFN; the AEC-Q100 automotive variants KSZ9031RNXUB-VAO and KSZ9031RNXVB-VAO use the 48-pin lead-free WQFN. The KSZ9031MNX version provides a 64-pin QFN footprint. Technically, the device integrates all front-end analog blocks - the 10/100/1000 Mbps PHY, MDI termination resistors, baseline wander correction, adaptive equalization, and crosstalk cancellation - to deliver robust 1000Base-T performance over CAT-5 cable. The RGMII interface supports 1.5V/1.8V/2.5V/3.3V HSTL signaling and provides TX/RX clocks, data, and control. Energy-detect mode drops power consumption to approximately 75 mW when the link partner is disconnected. Typical applications include automotive infotainment, telematics, ADAS camera links, industrial Ethernet gateways, automotive gateways, and in-vehicle networking backbones where AEC-Q100 qualification is mandatory. Designers also use this part in ruggedized industrial switches and routers that demand the same automotive-grade reliability. When designing with the KSZ9031RNXUB-VAO, follow the reference schematic's recommended 1.2V/2.5V power-rail decoupling and 25 MHz reference-clock layout. Use the integrated termination resistors to minimize external component count, and ensure the magnetics meet the IEEE 802.3 return-loss specification for the chosen cable length.

A low-latency 1000BASE-T receive path and integrated 1.2V LDO simplify BOM. Architecture is built on a DSP-based echo canceller and AFE using a 0.13um CMOS process, integrating all active magnetics-less PHY functions except the 1:1 isolation transformer and RJ-45. Reference clock can be sourced from a 25 MHz crystal or external oscillator. JTAG boundary-scan support is provided for board-level test. Typical applications include automotive infotainment Ethernet backbones, industrial Ethernet switches/routers, set-top box and IPTV MAC interfaces, network printers, gigabit uplink PHY for SBCs/SoCs, and ADAS camera networks. The 48-WQFN package is footprint-compatible with other KSZ9031 family members and several third-party Gigabit PHYs, easing dual-sourcing. When designing, place the KSZ9031 within 1 cm of the magnetics and route each MDI pair as a 100-ohm differential with intra-pair length matching under 0.5 mm. Provide a solid GND reference on layer 2 under the PHY, and decouple AVDD/AVDDPLL/DVDD with 0.1uF X7R plus 10uF bulk capacitors as close to each pin as possible. This page synthesizes distributor pricing, automotive-grade alternatives, and PCB-layout design notes beyond the manufacturer datasheet summary to support rapid PHY selection for Gigabit Ethernet designs.

A Gigabit Ethernet transceiver is a physical-layer device that connects a MAC (Media Access Controller) to the copper medium via twisted-pair magnetics, encoding/decoding 1000BASE-T/100BASE-TX/10BASE-T signaling and providing PCS, PMA, and PHY functions defined by IEEE 802.3 clauses 22-40. The KSZ9031 family belongs to the Ethernet PHY hierarchy (Ethernet transceiver -> physical layer device -> network interface IC) and supports GMII/MII or RGMII MAC-side interfaces depending on sub-variant, sitting between the SoC MAC and the RJ45/Magnetics front-end. Key features include 3.3V/2.5V/1.8V tolerant MAC-side I/Os, on-chip termination resistors, AEC-Q100 Grade 2 qualification (-40C to +105C), Energy-Efficient Ethernet (EEE) support per IEEE 802.3az, Wake-on-LAN, auto-negotiation with HP Auto-MDIX, and remote/local loopback for diagnostic verification of both analog and digital data paths. The WQFN wettable-flank package enables automated optical inspection (AOI) of solder joints - critical for automotive PCB assembly. Architecturally, the device integrates a DSP-based baseband processor, a low-noise analog front-end with on-chip LDO regulators, and an RGMII interface block that supports RGMII-ID (internal delay on TX, RX, or both). It interfaces directly to a single 3.3V supply (with internal regulation generating 1.2V core rails), reducing external BOM. Typical power consumption is approximately 450 mW active at 1 Gbps and 80 mW in EEE LPI state. Typical applications include automotive infotainment Ethernet, ADAS camera links, in-vehicle networking backbones, industrial Ethernet switches, and any design requiring a 1 Gbps RGMII PHY qualified for harsh environments. Compared to consumer-grade KSZ9031RNX (standard QFN-48), the -VAO part uses wettable-flank leads for solder joint inspection. When designing in, route the 125 MHz RGMII clock and data signals with matched impedance (typically 50 ohm SE) and length-matching to within the RGMII v2.0 spec (typically 50 mil tolerance on the PCB). Use a 25 MHz external crystal or 125 MHz LVCMOS reference; configure strap pins or MDIO registers for desired clock delay mode.

It features RGMII/GMII/MII MAC-side interfacing, an integrated 1.25 GHz PLL, on-chip termination, and LinkMD cable diagnostics for cable-plant fault detection. The device operates from a single 3.3V supply with internal 1.2V LDO regulation and consumes roughly 600 mW typical during 1000Base-T link operation. It is AEC-Q100 qualified for automotive Ethernet in-vehicle networking. An Ethernet PHY (physical layer transceiver) is a mixed-signal IC that converts digital MAC frames into analog line signals for transmission over copper twisted pair, then recovers and decodes incoming signals back into digital data. The PHY sits below the MAC layer in the OSI model and handles line coding (PAM-16 for 1000Base-T, MLT-3 for 100Base-TX, and Manchester for 10Base-T), echo cancellation, crosstalk mitigation, clock and data recovery, and link-training. The KSZ9131 belongs to the gigabit Ethernet PHY family, which is a subset of Ethernet interface ICs in the broader interface IC category under integrated circuits. Key features of the KSZ9131RNXC-TR include auto-negotiation and HP Auto-MDI/MDIX crossover at all three speeds, Energy Efficient Ethernet (EEE) IEEE 802.3az support, Wake-on-LAN, four programmable LED indicators, JTAG boundary-scan support, and a 1.8V/2.5V/3.3V tolerant RGMII I/O interface. The device uses a DSP-based architecture with echo and near-end/far-end crosstalk cancellers to achieve the 100-meter CAT-5 link budget required by IEEE 802.3. The KSZ9131 is built on a low-power CMOS process and uses adaptive equalization plus baseline wander correction to maintain robust performance over installed cable. Its integrated termination resistors eliminate the need for external 100-ohm resistor networks on each differential pair, reducing BOM count by about 8 resistors per port. The device supports both GMII and RGMII MAC interfaces, selectable at reset via strap pins. Typical applications include automotive in-vehicle networking gateways, industrial Ethernet switches and gateways, IP cameras and surveillance equipment, network routers and access points, and embedded industrial automation systems using EtherCAT or PROFINET. The automotive-grade qualification (AEC-Q100) makes it especially suited for telematics control units, ADAS sensor hubs, and zonal architectures that require Gigabit Ethernet over single twisted pair or quad twisted pair cabling. When designing with the KSZ9131, allocate a 50 MHz reference clock source (crystal or oscillator) and follow the reference layout in the datasheet. Both 3.3V and 1.2V rails are required (the 1.2V is generated internally from the 3.3V supply). Maintain 100-ohm differential impedance on MDI traces and keep the analog ground island isolated from digital switching returns to preserve SNR. This page consolidates distributor pricing, verified drop-in alternatives, and practical PCB layout considerations that complement the manufacturer datasheet and migration guide AN2918.

The KSZ9567R uses configuration strap pins to establish operating modes. According to the verified Microchip datasheet, RESET_N must be low while these pins are high impedance, allowing external pull-up or pull-down resistors to create configuration states that are sampled on the rising edge of RESET_N. This makes board-level mode selection deterministic, but every strap, reset, and supply connection must follow the datasheet reference circuit. Typical uses include industrial Ethernet gateways, networked automation equipment, embedded servers, communications infrastructure, and managed network interfaces requiring multiple gigabit ports in one package. Consolidating five PHY ports and two configurable interfaces reduces component count, but careful decoupling, controlled clocking, exposed-pad thermal management, and high-speed layout remain essential. Designers should use the manufacturer reference schematic and layout guidance, place high-frequency decoupling close to supply pins, provide a continuous thermal path through the exposed pad, and observe Ethernet magnetics and routing requirements. Firmware, management, and register compatibility must also be reviewed because a managed Ethernet switch is a system-level component rather than a simple physical-layer transceiver. This page consolidates verified manufacturer and distributor information, source links, application guidance, and replacement analysis. It also distinguishes electrically similar devices from verified pin-to-pin drop-in alternatives, helping engineers assess PCB reuse without treating package similarity as proof of compatibility.

What is a managed Layer-2 Ethernet switch IC? In the silicon taxonomy, a managed Ethernet switch sits between a simple PHY (physical-layer transceiver) and a full network processor. It performs MAC-layer forwarding, VLAN tagging, IGMP snooping, QoS prioritization, and traffic shaping autonomously, exposing configuration registers to a host CPU rather than running an external networking stack. The KSZ9893RNXI integrates two Gigabit PHYs alongside the switch fabric, which eliminates external magnetics-side components and reduces BOM and PCB area for embedded industrial designs where board real estate is at a premium. Key differentiating features include the integrated 1588v2 hardware timestamp engine for sub-microsecond PTP synchronization on industrial networks, the LinkMD TDR-based cable diagnostic function that pinpoints cable faults without external test gear, and on-chip termination resistors that simplify the magnetics interface. The device supports jumbo frames up to 9 KB, a 4096-entry forwarding table, and 128 kByte frame buffer architecture tuned for low-latency real-time traffic on factory and process-control networks.

Its IEEE 802.3 Ethernet switching core supports 10, 100, and 1000 Mbps operation while providing one additional configurable MAC port for uplink, inter-switch, or processor-facing connections. A managed Ethernet switch is a Layer 2 network-semiconductor device that receives Ethernet frames on one port, examines addressing information, and forwards traffic through selected output ports. The switch-controller hierarchy includes Ethernet switch, Layer 2 managed switch, Ethernet interface IC, network semiconductor, and integrated circuit. Compared with a discrete collection of PHY and switching components, the KSZ9896 integrates five copper PHYs, switching logic, management features, and a flexible MAC interface into one device, reducing board area and interface complexity. Important features include five integrated Gigabit PHYs, a sixth configurable MAC port, support for IEEE 802.3 operation, and host-control access through I2C and SPI interfaces. Automatic polarity correction, echo cancellation, and remote fault detection support reliable physical-layer links. The configuration strap pins allow the device to be initialized for different operating modes, while RESET_N provides a hardware reset function. Five of the six ports therefore support copper links, and the remaining port can be adapted to the required processor or uplink interface. The sixth port’s configurable MAC interface makes the KSZ9896 suitable for systems that must connect a switch fabric to a host processor using GMII, RGMII, MII, or RMII. This flexibility reduces the need for separate PHY devices in architectures requiring a high-speed processor-facing uplink. Interface selection should be matched to the host’s timing, voltage, and data-width requirements, because the MAC mode determines the required external components and the applicable throughput ceiling. Typical applications include industrial Ethernet equipment, embedded control systems, factory automation controllers, industrial gateways, networked measurement equipment, and compact embedded platforms requiring several Gigabit copper ports. The switch can serve as the central Layer 2 forwarding device in control cabinets, test systems, or industrial edge nodes. In a typical design, the five integrated PHY ports connect field devices or local computers, while the configurable sixth port interfaces to a host processor or another switch. The 128-TQFP exposed-pad package requires careful PCB layout. Follow the manufacturer’s land pattern and thermal-via recommendations, especially when high-port-count traffic causes sustained activity in the PHYs and switching core. Provide the required input, output, and interface decoupling capacitors close to their associated pins, and route high-speed MAC signals over continuous reference planes while minimizing stubs and unprotected routing lengths. This page combines the manufacturer’s six-port switching architecture, package information, interface options, engineering design notes, and verified sourcing guidance. It also distinguishes genuine drop-in coverage from related switch products whose port counts or interfaces make them unsuitable for a PCB-level substitution, helping engineers make a more reliable component-selection decision.

The device supports I2C and SPI management interfaces and implements Ethernet switching according to IEEE 802.3. An Ethernet switch is a network-semiconductor device that receives frames on one port and forwards them to the appropriate destination ports. A managed Layer 2 switch adds configurable port behavior, status monitoring, and traffic control beyond the basic function of an unmanaged switch. The KSZ9896 combines five copper Gigabit Ethernet PHYs with a flexible sixth-port MAC interface, allowing it to serve as the central switching element in industrial, automotive, communications, and embedded Ethernet equipment. Five of the six ports integrate 10/100/1000 Mbps PHYs, allowing the switch to support gigabit links while retaining 100 Mbps and 10 Mbps compatibility. The sixth port can be configured through GMII, RGMII, MII, or RMII, providing flexibility for connections to another Ethernet controller, FPGA, processor, or network interface. I2C and SPI host interfaces support configuration and status access for embedded systems. The managed switching architecture operates at Layer 2 and supports the IEEE 802.3 Ethernet functions required by the KSZ9896 family. Integrating five PHYs into the switch reduces the component count of a multi-port network design by eliminating several external PHY devices. The integrated MAC interface provides a configurable path to higher-speed or differently structured network interfaces without requiring a separate switch solely for interface conversion. Typical uses include industrial Ethernet controllers, automotive in-vehicle networking equipment, industrial gateways, embedded network appliances, and communications equipment with multiple copper ports. The combination of five integrated Gigabit PHYs and one configurable MAC interface is particularly useful when a design requires several local copper links plus a connection to a host processor, FPGA, or additional switching silicon. PCB implementation requires careful attention to the 128-pin TQFP exposed-pad footprint, high-speed differential routing, and thermal performance. The exposed pad must be connected to the appropriate ground plane with adequate via density, while each Ethernet magnetic interface requires its own carefully terminated network path. Review the manufacturer pin-description table and recommended layout guidance before assigning every power, ground, and signal connection. This product page combines the manufacturer’s switching capability overview with practical procurement and engineering guidance. It highlights the distinction between the five integrated PHY ports and the configurable sixth MAC port, clarifies interface-selection considerations, and organizes replacement questions around verified package and compatibility requirements rather than treating electrically similar switches as automatic substitutes.

Five of the seven ports integrate 10/100/1000 Mbps PHYs and the remaining two ports feature configurable SGMII, RGMII, MII, or RMII host interfaces for connecting to a host CPU, SoC, or external transceiver. The device is qualified for industrial temperature operation from -40C to +85C and supports I2C and SPI management interfaces for configuration, statistics, and QoS policy. A managed Layer-2 Ethernet switch is an IC that performs wire-speed forwarding of Ethernet frames between multiple physical ports while supporting VLAN tagging, QoS prioritization, IGMP snooping, port-based access control, and management via software. Switch ICs sit hierarchically between physical layer (PHY) transceivers and the network processor/host CPU, falling under the broader category of networking ICs within wired connectivity. Key features of the KSZ9897RTXI include IEEE 802.1Q VLAN support, 802.1p QoS with four priority queues per port, IPv4/IPv6 multicast IGMP/MLD snooping, port mirroring, ACL filtering, EEE (Energy Efficient Ethernet) per 802.3az, and integrated 1.5 kV Ethernet transformer isolation on the cable-side ports. The device uses strap pins for default configuration and supports EEPROM-less unmanaged mode. Architecturally, the KSZ9897RTXI uses a store-and-forward shared-bus fabric with an integrated Address Resolution Logic (ARL) table. The on-chip PHYs employ DSP-based echo and near-end crosstalk cancellation, supporting Cat-5 UTP cable runs up to 100 m. The two non-PHY ports can be configured as RGMII/MII/RMII for direct MAC-to-MAC connection to a processor, or as SGMII to interface with an external 1000BASE-T PHY or SFP cage. Typical applications include industrial IoT gateways, industrial Ethernet switches, IP cameras and surveillance backhaul, building automation, smart-grid RTUs, automotive Ethernet AVB bridges, telecom routers, and embedded routers requiring 5 or more managed Gigabit links on a single board. The 7-port count fits compact managed switches used in industrial control cabinets. Design consideration: plan PCB layout to keep the MII/RGMII/SGMII traces length-matched within 50 mil of the host SoC and provide solid ground stitching vias between port pairs to minimize crosstalk. The integrated PHYs require a 25 MHz reference crystal with 50 ppm accuracy for stable 1000BASE-T operation.

The device is designed for industrial-grade (-40C to +85C) operation and targets small-form-factor embedded networking designs. What is a managed Ethernet switch IC? A managed Ethernet switch is a single-chip device that integrates multiple physical layer transceivers (PHYs), Media Access Controllers (MACs), and a layer-2 packet-forwarding engine with configurable features such as VLANs, QoS, IGMP snooping, and port mirroring. In the component taxonomy, the KSZ9897 falls under Ethernet switch IC -> network interface IC -> interface IC -> integrated circuit.

Key features of the KSZ9897STXI include seven integrated gigabit ports, full wire-speed non-blocking switching, IEEE 802.1Q VLAN support, IPv4/IPv6 QoS with four priority queues per port, IEEE 1588v2 hardware timestamping, LinkMD cable diagnostic, tail-tag-free operation, and flexible SGMII/RGMII/MII/RMII expansion. It supports both store-and-forward and cut-through switching modes, includes an integrated EEPROM controller, and offers comprehensive cable diagnostics for proactive fault detection. The architecture pairs five integrated 10/100/1000 BASE-T PHYs with two selectable SGMII/RGMII/MII/RMII interfaces that allow designers to connect external PHYs, processors, or another switch. An integrated ARM-class management CPU offloads ACL processing, IGMP/MLD snooping, and storm control. The device supports jumbo frames up to 9 KB, 16K MAC address entries, and 1 MB of shared packet buffer memory, enabling low-latency line-rate operation at full gigabit wire speed on all ports simultaneously. Typical applications include industrial Ethernet switches, building automation gateways, IP surveillance NVRs, automotive Ethernet zonal gateways, smart energy / substation automation equipment, and IoT edge aggregation switches. The wide industrial temperature range and LinkMD diagnostics make it well suited for unattended or harsh-environment deployments. When designing with this part, ensure the integrated 1.2V and 2.5V LDO regulators are bypassed with the recommended capacitor network and that the 25 MHz reference clock meets the +/-50 ppm accuracy spec. The exposed pad must be soldered to a sufficient ground copper pour for thermal dissipation; without it, junction temperature can exceed 105C at full gigabit loading.

STMicroelectronics L6360TR is an IO-Link communication master transceiver IC for industrial sensor and actuator interfaces, operating from 18 V to 32.5 V and supporting PHY2 three-wire communication in COM1, COM2, and COM3 modes. The device provides a protected 500 mA L+ high-side driver, programmable high-side, low-side, or push-pull output stages with less than 2 Ω output resistance, and an additional IEC 61131-2 type 1 input. An IO-Link master transceiver is a specialized interface integrated circuit that combines digital communication, sensor excitation, and discrete input detection for industrial automation. Within the hierarchy of interface ICs, transceivers, and industrial communication semiconductors, the L6360 provides the electrical interface between a controller and an IO-Link sensor or actuator. It is designed to simplify master ports operating at COM1, COM2, or COM3 communication speeds. The L6360 supports COM1 at 4.8 kbaud, COM2 at 38.4 kbaud, and COM3 at 230.4 kbaud. Its protected 500 mA L+ high-side driver supplies connected sensors, while the programmable output stage can operate as high-side, low-side, or push-pull with less than 2 Ω resistance. These functions support flexible connection of compatible industrial sensors, actuators, and digital input devices. The monolithic transceiver architecture integrates an IO-Link physical layer with sensor power and input circuitry. Its 18 V to 32.5 V supply range accommodates common industrial control environments, and its VFQFN-26 exposed-pad package supports compact surface-mount layouts. The exposed thermal pad must be connected to ground and used for heat spreading when operating at elevated ambient temperatures or driving higher output loads. Typical uses include IO-Link master ports in factory automation, proximity and photoelectric sensors, industrial actuators, and distributed control systems. The L6360 is also appropriate when a machine controller must support multiple IO-Link communication speeds while combining a protected sensor supply with an additional digital input. PCB design should follow the manufacturer datasheet for pin assignment, exposed-pad connection, and external component selection. Decoupling must be placed close to the supply pins, the exposed pad should have adequate thermal-via and copper support, and high-current output paths should be sized to limit voltage drop across the L+ driver. This page combines verified manufacturer specifications, distributor pricing, package details, application guidance, and drop-in replacement research. The replacement analysis specifically distinguishes confirmed equivalents from related interface products that cannot be treated as pin-compatible substitutes.

Key features include a 10 mA selectable linear regulator, 5 V and 3.3 V compatible I/Os, a 0.3 A output current intervention threshold, and a fully protected output stage that can be configured as high-side, low-side, or push-pull. The output driver can sink and source resistive, capacitive, and inductive loads typical of industrial sensor coils, and the device integrates reverse-polarity, overcurrent, and thermal protection. The selectable linear regulator provides a clean supply rail for an external sensor MCU or signal-conditioning block. Architecturally, the L6362A (the die family to which L6362A belongs) is a monolithic dual push-pull driver with on-chip diagnostics and a wake-up detector for SIO mode. The integrated 10 mA LDO simplifies the sensor-side supply tree, and the configurable output stage allows the same IC to drive either a PNP (high-side), NPN (low-side), or push-pull sensor, eliminating the need for external H-bridges. The exposed pad on the VFDFPN-12 package keeps junction temperature within safe limits during sustained output currents near the 0.3 A intervention threshold.

L6364Q - Dual-Channel IO-Link Transceiver | STMicroelectronics
The STMicroelectronics L6364Q is a dual-channel IO-Link and SIO transceiver IC in a 20-pin QFN (4x4 mm) package, designed as the PHY interface between a microcontroller and the 24 V industrial sensor/actuator signaling cable. It embeds two physical channels with selectable 3.3 V / 5.0 V / high-side driver modes and integrates 50 mA 3.3 V and 5.0 V LDO regulators plus a DC-DC converter to supply the host MCU and external circuitry from the 24 V rail. As an IO-Link PHY, the L6364Q is a bridge transceiver (interface IC) positioned in the industrial-sensor signal chain: MCU -> IO-Link transceiver -> 24 V cable -> IO-Link master. It supports M-sequence handling, wake-up pulse generation, and SPI configuration from the host microcontroller so the device can be reused across discrete sensors, actuators, and binary (SIO) legacy modes. Key features include a wide 8 V to 36 V operating supply range compatible with industrial 24 V rails, integrated reverse-polarity and over-current protection on the high-side drivers, two independent CQ channels, dual LDO regulators (3.3 V and 5.0 V at 50 mA each) for host MCU supply, integrated DC-DC converter, and -40 C to +150 C extended industrial temperature range. The 20-pin QFN (4x4 mm) package minimizes PCB area for space-constrained sensor heads. Internally the L6364Q combines two C/Q output drivers with current limiting, two LDO regulators with power-good indication, a DC-DC controller for energy-efficient 24 V-to-low-voltage conversion, and an SPI interface for M-sequence parameterization. Compared with discrete IO-Link implementations, the L6364Q shrinks the BOM by replacing multiple protection devices, regulators, and the DC-DC passives with one qualified IC. Typical applications include industrial binary sensors and proximity switches, factory automation actuators with IO-Link connectivity, IO-Link sensor hubs and junction boxes, smart valve and valve-position feedback modules, robotics I/O modules, and process-control instrumentation. The wide input voltage range and integrated protection suit 24 V factory bus operation, while the dual channels enable single-chip two-port sensor nodes. When designing with this part, ensure that thermal management of the QFN exposed pad is adequate - the dual LDO currents plus DC-DC losses can produce 500 mW dissipation at full load. Use the SPI interface to switch from SIO mode to IO-Link mode dynamically without disturbing the in-progress IO-Link communication frame. This page synthesizes distributor pricing, real ST X-NUCLEO-IOD02A1 expansion-board integration notes, and practical design considerations that extend beyond the L6364 datasheet block diagram.
L6451013TR - 28-Channel Inkjet Driver, 5.25 V | STMicroelectronics
The STMicroelectronics L6451013TR is a 28-channel inkjet print-head driver integrated circuit supplied in a 44-lead PLCC package. It operates from a nominal 5.25 V maximum supply rating, with distributor technical data also identifying a 4.75 V to 5.25 V supply range and a 0°C to 70°C commercial temperature grade. The device is designed for driving the high-voltage, high-current print-head loads found in inkjet printing equipment. An inkjet driver is a specialized interface IC that converts low-voltage logic commands into controlled high-voltage and high-current drive signals for piezoelectric inkjet nozzles. In the system hierarchy, this device is a printer-specific peripheral driver within the broader interface IC and power-driver categories. Its 28 output channels allow one controller to manage multiple print-head elements while reducing the number of discrete drivers required at the board level. The L6451013TR is listed as a 28-channel driver with a nominal peak output current limit of 2 A and a maximum supply voltage rating of 5.25 V. The 44-terminal PLCC package provides the mechanical footprint used in the original inkjet-printer controller boards. The commercial temperature range supports operation in controlled indoor printer and imaging environments, but the 0°C to 70°C limit is a key constraint for designs operating across wider industrial temperature ranges. Typical applications include inkjet print-head carriage electronics, multi-nozzle print-head assemblies, printer engine control boards, and specialized inkjet dispensing systems. Because it is a dedicated 28-channel print-head driver rather than a general-purpose logic buffer, its timing inputs, protection features, and pin functions are intended for a particular inkjet drive architecture. The principal design consideration is the relationship between the 2 A nominal peak output current rating, the inductive or capacitive load presented by the print head, and the protection network connected to each channel. PCB routing must minimize loop area in high-current drive paths, and unused or reserved outputs should be handled according to the manufacturer pin-description table. Production quantities should be confirmed before layout release because this is an older specialized printer-driver family with limited channel-count substitution. This page consolidates package, channel-count, supply, temperature, and output-current information into a structured engineering reference. It also distinguishes the documented L6451013TR ratings from specifications that must be taken directly from the manufacturer datasheet, including precise channel timing, dropout behavior, and protection thresholds.
L9613B - ISO 9141 Medium-Speed Data Interface | STMicroelectronics
The STMicroelectronics L9613B is a monolithic medium-speed data-interface IC containing standard ISO 9141-compatible interface functions. The manufacturer identifies the L9613 as a monolithic integrated circuit intended for automotive data-interface applications, while the L9613B ordering code is the subject of the supplied distributor and datasheet records. Its core function is to provide the physical-layer interface required by ISO 9141-compatible diagnostic communication systems. The supplied L9613 datasheet is 15 pages according to the verified document listing. An ISO 9141-compatible data interface is a wired automotive communication interface that connects an automotive diagnostic or test system to a vehicle network through defined K-line and related signal functions. Within the product hierarchy, the L9613B is a monolithic interface IC, a communication transceiver, and therefore a semiconductor-level realization of ISO 9141 physical-layer functions. This classification distinguishes it from general-purpose logic ICs, memory devices, microcontrollers, and analog power-management components. The verified manufacturer material confirms several important implementation details. The device includes standard ISO 9141-compatible interface functions. According to the manufacturer datasheet, the K, LO, and RX outputs have output-voltage behavior that varies with output current, including a transition related to RON multiplied by IOUT and a 2 × RON × IOUT plus UBE condition. The document also states that K, RX, and LI pins include protection against overvoltage, short circuits to ground or VS, and being driven beyond the supply rails. TX, RX, and LI receive comparable protection when internal pull-up behavior is considered. L9613B is intended for medium-speed data-interface systems using ISO 9141-compatible signaling. Its monolithic construction consolidates the required interface functions into one package, helping designers reduce the number of discrete interface elements around a vehicle diagnostic connector or tester. The documented output behavior makes the K, LO, and RX nodes important when designing cable termination, fault-recovery behavior, and logic-level compatibility. Exact electrical limits, timing values, supply range, and package dimensions must be taken from the manufacturer datasheet for production design. Typical use cases include automotive diagnostic testers, engine-control-unit service interfaces, vehicle workshop equipment, and ISO 9141-compatible electronic control modules. In these systems, the L9613B provides the physical-layer interface between a controller and an external diagnostic tool. Selection should account for the target vehicle network, cable length, bus topology, connector standard, protection requirements, and whether the interface must support legacy ISO 9141 rather than a newer protocol. The L9613B is not a general-purpose CAN transceiver and should not be treated as a substitute for CAN, LIN, or OBD-II protocol engines. For implementation, follow the manufacturer’s recommended input, output, decoupling, grounding, and protection arrangements. Verify every external resistor, capacitor, connector, and transient-protection device against the absolute maximum ratings and application diagrams in the L9613 datasheet. PCB signal integrity and automotive transient immunity are especially important because the interface connects directly to conductors entering a vehicle environment. Do not infer package pin numbers or package compatibility from distributor descriptions alone; use the official pin configuration before layout or substitution. This page consolidates the verified STMicroelectronics product page, manufacturer PDF, distributor listings, and targeted cross-reference results. It also separates confirmed ISO 9141 functionality from unverified quantities, making the documentation useful for preliminary design evaluation, sourcing, datasheet discovery, and drop-in-replacement investigation without presenting missing electrical or packaging data as established facts.
L9613B013TR - ISO 9141 Transceiver | STMicroelectronics
STMicroelectronics L9613B013TR is a monolithic ISO 9141-compatible automotive interface transceiver with one transmitter and one receiver, supplied in an 8-pin SOIC package. Its operating supply range is 4.8 V to 36 V, with transient operation up to 40 V. The interface is designed for K-line communication links in vehicle electronic control units and body electronics modules. An ISO 9141 interface transceiver is an integrated circuit that combines a line driver and line receiver with the electrical interface required by a K-line serial network. It belongs to the automotive interface IC category, where a controller uses a physical-layer transceiver to exchange diagnostic or application data with a vehicle bus. The L9613 provides the hardware layer between a microcontroller's serial I/O signals and the vehicle wiring harness. The L9613B013TR operates from a 4.8 V minimum supply and reaches a 36 V maximum supply, while tolerating transients to 40 V. Reverse-battery protection extends to VS values down to -24 V. These characteristics make the device suitable for automotive electrical environments where supply transients, load dumps, and incorrect battery polarity must be considered. A maximum signaling rate of 130 kbps is identified for the component. STMicroelectronics describes the L9613 as a monolithic integrated circuit containing standard ISO 9141-compatible interface functions. Integrating the transmitter and receiver reduces the number of external line-interface components required around a vehicle diagnostic controller. The 8-pin SOIC outline is compact enough for body-control and engine-control electronics while remaining compatible with standard small-outline surface-mount assembly methods. Typical applications include automotive diagnostic interfaces, engine control units, transmission controllers, body control modules, instrument clusters, immobilizers, and other embedded vehicle systems that communicate over a K-line physical layer. Using a dedicated transceiver helps isolate the controller from the wired diagnostic network and supports operation across the voltage range expected in automotive electrical systems. PCB implementation should follow the manufacturer's application diagram for decoupling, connector-side protection, and signal routing. Keep the transceiver close to the vehicle connector or bus interface, provide a stable local supply reference, and verify the connected ECU’s logic levels. The SOIC footprint leaves adequate routing space for bypassing and external protection components, but automotive transient and ground-loop requirements remain the dominant layout constraints. This product page combines the manufacturer interface description with package, voltage, speed, and sourcing details, then adds pin-assignment guidance, practical PCB considerations, application-specific selection advice, and a comparison of documented alternative variants. Engineers can use these notes to evaluate the L9613B013TR for an existing ISO 9141 circuit before requesting a quote and confirming supply availability.
L9615D - 500 kbaud CAN Transceiver | STMicroelectronics
The STMicroelectronics L9615D is a bidirectional 1/1 CAN bus transceiver with signal-conditioning capability for CAN controllers, data rates up to 500 kbaud, and an 8-pin SOIC package. It supports both shielded and nonshielded CAN bus lines, generates differential transmitter outputs, and includes selectable slope control for 500 kbaud and 125 kbaud operation. Its CAN outputs are short-circuit protected to 36 V, while shutdown detection helps isolate faulted bus conditions. A CAN transceiver is an interface IC within the broader transceiver and physical-layer hierarchy. It converts logic-level TXD and RXD signals from a CAN controller into a differential CANH/CANL bus output and converts the received differential bus state back into a controller-compatible RXD signal. The L9615 therefore belongs to the CAN interface and industrial communication networking category, where robust physical-layer behavior helps a controller communicate reliably over long, noisy wiring harnesses. The L9615D supports data rates up to 500 kbaud and meets ISO/DIS 11898 requirements stated in the manufacturer-related datasheet information. Two adjustable slope-control states accommodate 500 kbaud and 125 kbaud networks, allowing engineers to reduce radio-frequency interference and electromagnetic interference through controlled edge rates. Differential signaling provides common-mode rejection, bidirectional operation supports both transmit and receive paths, and 36 V short-circuit protection improves robustness against accidental bus faults. The L9615 uses slope control as an important signal-integrity feature rather than relying only on rise and fall-time behavior inherent to the output drivers. Slower transitions can reduce high-frequency emissions and ringing on long harnesses, while the faster setting supports the upper stated CAN data rate. The selected operating mode must therefore be matched to the configured network bit rate and the physical bus characteristics. The transceiver is designed for controller-centered architectures in which a CAN controller manages arbitration, frame handling, error detection, and bus arbitration. Typical uses include industrial automation equipment, automotive electronics, building automation, robotics, embedded control systems, and other CAN networks operating at 125 kbaud or 500 kbaud. In a typical design, the L9615D sits between a microcontroller or dedicated CAN controller and the CANH/CANL pair. External network termination, common-mode choke selection, transceiver supply decoupling, and protection-device coordination remain important board-level considerations. Designers should verify the absolute maximum ratings, recommended operating conditions, pin configuration, and application circuit in the official STMicroelectronics documentation before layout release. Because the supplied search data does not expose the complete official pin table or the package drawing, this page does not infer individual pin names. It also avoids claiming undocumented electrical thresholds. The verified starting price is US$0.5310 as of 2026-10-28. This page combines verified manufacturer descriptions, distributor package and availability information, ISO/DIS 11898 and 500 kbaud operating details, and engineering-focused selection guidance. It separates confirmed specifications from unavailable parameters and does not pad the alternatives list with reel-code variants or devices whose pin compatibility cannot be substantiated.
L9615D013TR - 500 kbaud CAN Transceiver | STMicroelectronics
The STMicroelectronics L9615D013TR is a single-channel CAN bus transceiver designed for bidirectional signal conditioning between a CAN controller and a twisted-pair CAN network. It supports data rates up to 500 kbaud from a 4.5 V to 5.5 V supply and is packaged in an 8-pin SOIC. The device provides one transmitter and one receiver, differential bus outputs, short-circuit protection, and shutdown detection. A CAN transceiver is an interface IC that converts logic-level transmit and receive signals into the differential voltages carried by a CAN bus. Its position in the hierarchy is CAN transceiver → CAN interface IC → interface integrated circuit → semiconductor. Unlike a physical-layer transformer or an isolated digital transceiver, the L9615 connects a controller directly to the bus while adding the driver, receiver, protection, and biasing functions required for reliable automotive or industrial communication. Key characteristics include operation up to 500 kbaud, conformance with ISO/DIS 11898, a 4.5 V to 5.5 V supply range, and short-circuit protection for bus outputs exposed to voltages up to 36 V. Slope control reduces radio-frequency interference during transitions. The half-rate CANH and CANL bus arrangement operates from a single transceiver perspective, while the package provides a compact surface-mount footprint for control modules and electronic control units. Internally, the transmitter converts a logic-level input into a dominant differential output across CANH and CANL. The receiver interprets the differential bus voltage and presents a logic-level output to the CAN controller. The transceiver also manages the recessive state, bus biasing, fault detection, and output-stage protection. Because the L9615 is a non-isolated device, its ground reference must be compatible with the controller and the rest of the CAN node. Typical applications include automotive body and comfort modules, industrial automation controllers, elevator systems, building-automation equipment, and embedded CAN gateways. It is particularly useful where a classic 500 kbaud CAN network is used instead of a higher-bandwidth CAN FD controller. The 8-SOIC package also makes the device suitable for designs that already use conventional surface-mount PCB assembly processes. When laying out the PCB, place the transceiver close to the bus connector and keep the CANH and CANL traces as a short, closely coupled pair. Provide the supply decoupling recommended in the manufacturer datasheet, and verify the controller transceiver logic levels and termination arrangement before layout release. The operating temperature range indicated for this ordering code is -40 °C to 110 °C.
L9637D - ISO 9141 Automotive Bus Transceiver | STMicroelectronics
The STMicroelectronics L9637D is an ISO 9141-compatible monolithic automotive bus transceiver with a 4.5 V to 36 V operating supply range, 40 V transient tolerance, and reverse-battery protection down to -24 V. It is supplied in an 8-pin SOIC package for surface-mount assembly in automotive diagnostic and communication interfaces. An automotive bus transceiver is an interface integrated circuit that combines bus-driver and receiver functions with the electrical protection and signal conditioning required to connect a host controller to a vehicle network. The L9637 belongs to the broader ISO 9141 interface transceiver hierarchy, where automotive diagnostics, K-line communication, and bidirectional serial links are the primary application domains. Key features include standard ISO 9141-compatible interface functions, bidirectional serial communication, reverse-battery protection, and a wide operating supply range. The monolithic design reduces the number of discrete components associated with a vehicle diagnostic interface. Its 8-pin SOIC format also supports compact surface-mount layouts and automated electronic assembly. The L9637 is intended for bidirectional communication between an automotive diagnostic tool, ECU, or other K-line interface and its associated controller. A 4.5 V minimum operating supply permits use in 5 V-class electronic systems, while operation up to 36 V provides headroom for automotive load-dump environments. The specified 40 V transient capability and -24 V reverse-supply protection are particularly important in vehicle electrical systems where wiring transients and accidental battery reversal can occur. Typical applications include ISO 9141 diagnostic interfaces, automotive ECU test equipment, bidirectional K-line links, vehicle communication modules, and service-bus diagnostic systems. The device is also suitable for industrial communication equipment that must reproduce an ISO 9141 bus interface. System-level suitability still depends on the exact bus waveform, bus speed, external resistors, connector protection, and ECU timing implemented around the transceiver. For PCB design, keep the bus connection and supply-return paths short, follow the manufacturer application schematic for external components, and place protection structures close to the vehicle connector. Designers should verify transient, ground-offset, and reverse-polarity conditions at the system level rather than relying only on the IC ratings. The available verified data does not provide the detailed pin table, temperature range, current limits, or timing characteristics. This page consolidates the verified STMicroelectronics product description, supply-protection limits, package information, ordering references, and distributor links into one engineering-oriented source. It also documents where pricing, pin-level, lifecycle, and drop-in replacement evidence remains unavailable, preventing unsupported claims from being presented as verified fact.
