EtherCAT Slave Controller with Integrated PHYs for the Internet of Things

Microchip Technology’s LAN9252 is a stand-alone EtherCAT slave controller with two 10/100 PHYs. Its dual 10/100 Ethernet transceivers support both fiber and copper, along with cable diagnostics capabilities. In addition, the LAN9252 supports traditional Host Bus and SPI/SQI communication, along with standalone digital I/O interfaces, enabling you to select from a wide range of microcontrollers when implementing the real-time EtherCAT communications standard. Additionally, the LAN9252 reduces system complexity and cost for developers using EtherCAT in factory-automation, process-control, motor/motion-control and Internet of Things (IoT) industrial-Ethernet applications.Microchip LAN9252 EtherCAT

The LAN9252 EtherCAT slave controller includes 4 KB of Dual-Port RAM (DPRAM) and three Fieldbus Memory Management Units (FMMUs). It also includes cable diagnostics support that allows field service technicians to rapidly and effectively diagnose line faults and provides for fiber connectivity. This EtherCAT slave controller is available in commercial, industrial and extended industrial temperature ranges, in low pin count and small body size QFN and QFP-EP packages.

To enable development with the LAN9252, two Microchip evaluation boards supporting various system architectures are available. The systems demonstrate how to interface to the LAN9252 through basic I/O connections or to microcontrollers such as the 32-bit PIC32MX family via serial communications. A Software Development Kit (SDK) is also available. The boards—EVB-LAN9252-HBI and EVB-LAN9252-DIGIO—cost $300 each.

The LAN9252 EtherCAT slave controller is available for sampling in 64-pin QFN and QFP-EP packages, starting at $7.01 each, in 10,000-unit quantities.
