Datongda Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market, announced that its subsidiary has launched the EtherCAT interface reference solution based on TI C2000 DelfinoTMTM S320F2837xD.
TI's highest performance C2000 DelfinoTMTM S320F2837xD is a powerful 32-bit MCU with dual CPU and dual CLA for a total system throughput of up to 800 MIPS. With new VCU and TMU accelerators, PWM enhancements, and 16-bit precision ADCs and more analog and control peripherals, the microcontroller can handle the most advanced control loop challenges such as industrial drives and servo motor control, solar inverters And converters, digital power, power delivery, and power line communication.
Its 32-bit C28x-architecture CPU core delivers 200MHz of signal processing performance with analog and control peripherals, allowing designers to integrate control architectures. Its CLA Real-Time Control Coprocessor is a stand-alone 32-bit processor that runs at the same speed as the main CPU and executes code concurrently with the main C28x CPU. The dual C28x+CLA architecture enables intelligent partitioning between various system tasks and effectively doubles the computational performance of the real-time control system. The performance of the C28x CPU is further enhanced by the new TMU Accelerator and VCU Accelerator, which quickly executes algorithms that include trigonometric operations common in transform and torque loop calculations; VCU Accelerators reduce complex mathematical operations common in coding applications time.

Datong Dayou also demonstrated how to connect the C2000 Delfino MCU to the EtherCATTM ET1100 Slave Controller based on the EtherCAT interface reference design of the TI DelfinoTMTM S320F2837xD 32-bit MCU. The interface supports multiple demultiplexed address/data buses for maximum bandwidth and minimum latency, and supports SPI mode for low pin count EtherCAT communications. The slave controller reduces the fieldbus communication processing load based on 100Mbps Ethernet, thus eliminating CPU overhead for these tasks.
