Overview

This reference design implements a cost-optimized high EMC immunity EtherCAT slave (dual ports) with SPI-interface to the application processor. The hardware design is capable of supporting multi-protocol industrial ethernet and field-busses using the AMIC110 industrial communications processor. The design runs on a single 5-V supply; a PMIC generates all the necessary on-board rails. The EtherCAT slave stack can run on the AMIC110 or on the application processor using a serial peripheral interface (SPI). With a hardware switch, the AMIC110 can be configured to boot the EtherCAT slave firmware from SPI flash or to boot from application processor through SPI. The design has been tested for IEC61800-3 EMC immunity with a standard industrial PLC running the EtherCAT master. A JTAG interface accelerates custom firmware development.

Features
  • Passes EtherCAT slave conformance testing (CTT)
  • Software-programmable multi-protocol industrial Ethernet and field bus support using AMIC110 communicatoin processor
  • Exceeds IEC61800-3 EMC immunity requirements running EtherCAT on both ports:
    • +/-6kV ESD CD per IEC 61000-4-2
    • +/-4kV EFT per IEC 61000-4-4 at criterion A
    • +/-2kV surge per IEC 61000-4-5 at criterion A
    • IEC61000-4-6 conducted RF at criterion A
    • CISPR 11 / EN55011 Class A low-latency, robust 10 or 100 MBit Ethernet PHYs DP83822
    • Low-latency, robust 10- or 100-Mbit Ethernet PHYs DP83822
  • Cost-optimized, easy power management using single PMIC to supply entire board from a preregulated 5-V supply
  • Operation over industrial temperature range, total board power consumption less than 1.25 W in typical use case; no heatsink required for operation up to 85oC ambient
Enterprise systems

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
