EtherCAT interface for high performance MCU reference design
This reference design from Texas Instruments demonstrates how to connect a C2000 Delfino MCU to an EtherCAT ET1100 slave controller. The interface supports both demultiplexed address/data busses for maximum bandwidth and minimum latency and a SPI mode for low pin-count EtherCAT communication.
The slave controller offloads the processing of 100Mbps Ethernet-based fieldbus communication, thereby eliminating CPU overhead for these tasks.
Features
- High-Bandwidth, low-latency interface to Beckhoff ET1100 EtherCAT Slave Controller.
- Asynchronous 16-bit parallel interface with demultiplexed address/data bus.
- Eliminates CPU overhead for EtherCAT frame processing.
- Includes example code for direct memory R/W of ET1100 Dual-port RAM.
