TRINAMIC Motion Control has launched two new EtherCAT slave controllers, the TMC8461 and TMC8462. Both controllers are optimized for real-time response in industrial IoT, automation, and other applications, and come with integrated motor control peripherals. The TMC8461 and TMC8462 are the world's first EtherCAT slave controllers with high voltage I/Os capable of 24 V and two integrated switching regulators. Additionally, the TMC8462 has two integrated Ethernet PHYs for minimized board space. Both ICs eliminate latency by incorporating PWM and step/dir I/O peripherals that make routing through the firmware of an application processor redundant. The slave controllers come with a broad array of peripherals and features, including an integrated smart-peripherals block accessible from an MCU or EtherCAT master, as well as an SPI master and encoder interface that can be directly mapped to the process data object (PDO) by the memory manager. To ensure wide interoperability, the TMC8461 and TMC8462 communication hardware has been verified as 100% compatible with the existing Beckhoff EtherCAT slave controller through extensive interoperability testing.
