TRINAMIC Motion Control extends its dedicated EtherCAT slave controller integrated motor control peripheral ic portfolio. TMC8461 and TMC8462 are the world's first EtherCAT slave controllers with 24 V high voltage I/O and two integrated switching regulators. TMC8461-BA uses a BGA144 (10 x 10) package and TMC8462-BA uses a small BGA121 (9 x 9) package. The equipment meets the automotive temperature specification of - 40 ° C to+125 ° C.
In addition, TMC8462 has two additional integrated Ethernet PHYs to minimize board space. These two ICs eliminate the delay by combining PWM and step/dir I/O peripherals. These peripherals make the routing through the application processor firmware redundant, making it an ideal choice for industrial IoT, automation and other applications requiring real-time response.
EtherCAT extends the function set of EtherCAT core technology, and the slave controller is equipped with a wide range of peripherals and functions. The integrated intelligent peripheral block can be accessed from MCU or EtherCAT host. In addition to PWM unit and step/dir interface, it can also be directly mapped to SPI host and encoder interface of process data object (PDO) through memory manager. This unique SPI interface supports reading or writing DAC from ADC or encoder without delay.
The integrated circuit includes an independent mode, which enables the integrated peripherals to map directly to the bus registers, while the parallel external MCU can perform higher-level protocol operations. In order to ensure extensive interoperability, through extensive interoperability testing, TMC8461 and TMC8462 communication hardware has been proven to be 100% compatible with existing Beckhoff EtherCAT slave controllers.
Like all Trinamic's equipment, ICs benefits from the company's comprehensive development ecosystem, known as "Landungsbrucke". This includes evaluation boards, reference designs, and EtherCAT Cortex mcu software stack samples for TMC8461 and TMC8462 devices. All configuration and parameterization tools are merged into Trinamic's integrated development environment (IDE). These devices can be used with any MCU with SPI or independently in SPI simulation mode.
