MCHPLAN9254-V/JRX
Overview
The LAN9254-V/JRX is a 3-port EtherCAT device controller with integrated dual 10/100 Ethernet PHYs designed for high-performance industrial automation. It features 8192 bytes of Process Data RAM and 32 digital GPIOs, supporting flexible interfaces including SPI, SQI, and MII. The device is rated for extended industrial temperatures from -40C to 105C, making it suitable for harsh environment deployments.
Why Choose This Part
This controller minimizes system BOM by integrating dual PHYs with HP Auto-MDIX and an internal 1.2V regulator. It offers significant design flexibility with 32 GPIO pins and support for SQI (Serial Quad Interface) to reduce pin count while maintaining high throughput. The inclusion of cable diagnostics and Wake on LAN (WoL) enhances system maintainability and power efficiency.
Applications
Key Specifications
Getting Started
Begin development with the Microchip EVB-LAN9254 EtherCAT Evaluation Board and the Microchip MPLAB Harmony v3 framework, which provides necessary drivers and EtherCAT stack support. Engineers should utilize the integrated cable diagnostic features and the Beckhoff Slave Stack Code (SSC) Tool for protocol configuration.
