LAN9252V/ML - 2/3-Port EtherCAT Controller | Microchip
MPN： LAN9252V/ML ✓ 啟用中LAN9252V/ML 概覽
An EtherCAT slave controller is an industrial communication integrated circuit that manages EtherCAT slave-side processing and interfaces a device to an EtherCAT network. The LAN9252 belongs to the broader hierarchy of EtherCAT controller, industrial Ethernet interface, network interface controller, interface IC, and semiconductor. Integrating the Ethernet PHYs with the EtherCAT controller reduces the external component count compared with a discrete PHY implementation and provides a defined interface between the EtherCAT network and the embedded control system.
Key verified features include support for two or three EtherCAT ports, two integrated full-duplex 100BASE-TX PHYs, 100Mbps operation, HP Auto-MDIX, a synchronous SPI/SQI host interface, Digital I/O Mode, and support for 100BASE-FX through an external fiber transceiver. The 64-QFN package is identified by the verified distributor listings as a 9x9 mm surface-mount package.
The LAN9252V/ML uses two integrated Ethernet PHYs to support copper-based 100BASE-TX links and can also participate in fiber-based networks when the required external transceiver is added. Its architecture is intended for industrial EtherCAT slave equipment in which network connectivity, deterministic EtherCAT processing, and host-controller integration must coexist within a compact embedded design.
Typical applications include industrial automation, motion-control equipment, factory I/O modules, robotics, PLC interfaces, and industrial Ethernet gateways. The LAN9252V/ML can connect embedded control electronics to EtherCAT infrastructure through 100BASE-TX while exchanging register and control data with a host MCU over the synchronous SPI/SQI interface. Digital I/O Mode provides an additional mechanism for the EtherCAT master to control or monitor device signals.
When designing around the LAN9252V/ML, verify the exact board layout, exposed-pad requirements, clocking, transceiver connections, and Digital I/O signal assignments against the manufacturer datasheet before release. The LAN9252V/ML is not a general-purpose Ethernet switch; its primary role is EtherCAT slave-controller connectivity. For 100BASE-FX implementations, include the external fiber transceiver and its associated isolation, interface, and layout requirements in the system design.

典型應用
LAN9252V/ML 適用於 6 應用s: Industrial Motion Control, EtherCAT I/O Module, Factory Automation Gateway, Robotics Control Interface, PLC Communication Module, Machine Vision Data Interface.
Industrial Motion Control
The LAN9252V/ML fits industrial motion-control equipment because it combines a 2/3-port EtherCAT slave-controller configuration with two integrated full-duplex 100BASE-TX PHYs operating at 100Mbps. A motion controller or drive can use the synchronous SPI/SQI interface to exchange commands and status with its host MCU while EtherCAT connects the axis to the factory network. Digital I/O Mode also permits an EtherCAT master to monitor or control assigned device signals. The principal design constraint is that this is a 100BASE-TX-focused controller, so network bandwidth and cable topology must match the selected EtherCAT architecture.
推薦
EtherCAT I/O Module
The LAN9252V/ML is appropriate for a distributed industrial I/O module because its two integrated Ethernet PHYs support 100Mbps full-duplex 100BASE-TX links and the device can operate as a 2/3-port EtherCAT slave controller. A host MCU can read input states and write output commands through the synchronous SPI/SQI interface, while Digital I/O Mode supports master-controlled signal handling. With HP Auto-MDIX, the module can accept direct-connect or crossover cables, simplifying field installation. Designers should validate isolation, grounding, magnetics, and connector requirements against the final I/O-node safety and EMC architecture.
推薦
Factory Automation Gateway
The LAN9252V/ML can serve as the EtherCAT-facing controller in a factory automation gateway that must bridge embedded equipment to a real-time industrial network. Its two integrated full-duplex 100BASE-TX PHYs provide two 100Mbps network interfaces, while the 2/3-port EtherCAT configuration supports line, star, or ring-oriented fieldbus arrangements selected by the system architecture. The synchronous SPI/SQI host interface allows an embedded processor to exchange process data and diagnostics. Digital I/O Mode provides direct EtherCAT master visibility into monitored or controlled signals, reducing the need for separate software-only status pathways.
推薦
Robotics Control Interface
The LAN9252V/ML supports EtherCAT-connected robotics when a robot controller needs a compact interface to distributed actuators, sensors, and safety-related I/O. The two integrated 100BASE-TX PHYs allow the embedded controller to participate through copper links at 100Mbps, and the synchronous SPI/SQI interface provides a direct path between the EtherCAT controller and a real-time MCU. Digital I/O Mode is useful when the EtherCAT master must observe or command application-specific signals. System designers must still implement appropriate galvanic isolation, EMI control, magnetic-interface components, and safety mechanisms outside the controller.
推薦
PLC Communication Module
The LAN9252V/ML is well matched to a PLC communication module because it integrates EtherCAT slave-controller functionality with two full-duplex 100BASE-TX PHYs and a host-facing synchronous SPI/SQI interface. A PLC or embedded controller can exchange cyclic data and diagnostics over the network while using Digital I/O Mode for master-managed signals. HP Auto-MDIX supports field cabling flexibility, and 100BASE-FX can be introduced with an external fiber transceiver where electrical isolation or longer-distance fiber links are required. The final module must add the required Ethernet magnetics or optical interface and industrial EMC protection.
推薦
Machine Vision Data Interface
The LAN9252V/ML can support a machine-vision subsystem that needs deterministic EtherCAT participation rather than conventional office-style Ethernet connectivity. The controller’s two 100Mbps full-duplex PHYs can connect embedded vision electronics to an EtherCAT network, and the synchronous SPI/SQI interface can link the ESC to an image-processing or real-time host processor. Digital I/O Mode permits the EtherCAT master to monitor trigger, ready, or status signals directly. The 64-QFN 9x9 mm package supports compact controller boards, although high-speed camera data should use a separate suitable interface rather than the 100Mbps EtherCAT links.

主要差異化特點
- Integrated dual-PHY EtherCAT connectivity (對比LAN9252/ML)
- Same-package same-family replacement candidate (對比LAN9250V/ML)
- Host-to-EtherCAT integration (對比LAN9250V/ML)
設計說明
Use the manufacturer LAN9252 datasheet as the controlling source for the 64-QFN 9x9 mm footprint, exposed-pad geometry, via pattern, and Ethernet magnetic-interface layout. Place the external Ethernet magnetics and their required passive networks close to the relevant PHY connections, and route each differential pair as a controlled-impedance pair with minimal length mismatch. The supplied evidence does not include the complete pin map, so do not release the PCB layout from a generic QFN-64 template.
Separate the synchronous SPI/SQI host interface from the Ethernet differential pairs and clock-sensitive circuitry to reduce coupling. Provide the decoupling network and return path required by the manufacturer datasheet at the supply pins, and keep the exposed-pad thermal and electrical requirements consistent with the package drawing. If 100BASE-FX is used, allocate the external fiber transceiver and its isolation network according to the selected optical device rather than adapting a copper-only layout.
Do not treat LAN9252V/ML as a general-purpose 1Gbps Ethernet switch or assume that a cable connection alone completes an industrial network design. The verified interfaces are two full-duplex 100BASE-TX PHYs, 100Mbps operation, EtherCAT slave control, and a synchronous SPI/SQI host path. Confirm the exact ordering suffix, pinout, electrical limits, Digital I/O mode requirements, and firmware or master compatibility against Microchip documentation before substituting another LAN925x-family device.
合規資訊
The verified manufacturer and distributor snippets do not provide formal RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 statements for the exact ordering code. The product is an industrial Ethernet interface IC, so AEC-Q100 is treated as not applicable rather than qualified.
