EtherCAT Slave and Multi-Protocol Industrial Ethernet Reference Design

1 января 2018

The TIDA-00299 reference designimplements a cost-optimized 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 has a 5-V input. A single PMIC generates all rails required onboard. 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 is in BoosterPack™ Plug-in Module form factor with a connector compatible to the TI LaunchPad™ Development Kit for easy evaluation with a C2000™ MCU. A JTAG interface accelerates custom firmware development.
