The TMC8460 is an EtherCAT slave controller with multifunction I/O for industrial automation, robotics and other automated equipment applications. The device is suitable as a step/ direction output and SPI master for example without using an additional microcontroller. The TMC8460 provides an a/b/n incremental, PWM, SPI and step/direction interface, general purpose IOs, and connects to the EtherCAT® field bus with two MII interfaces. The device requires 1.2V and 3.3V for logic and IO supply. * Package: VFGG400, 17mmx17mm Very Fine Pitch Ball Grid Array, 0.8mm pitch * Trinamic Multi-Function and Control IO Block (MFCIO) * 8 Digital general purpose IO, individually configurable * Incremental encoder input (ABN), single ended * Step & direction output with internal step rate generator * 3-ch PWM block with configurable frequency, duty cycle, dead times * Generic SPI master interface with up to 4 slaves, e.g., to connect Trinamic ICs * Configurable IRQ and event signal * Configurable watchdog for outputs and inputs * Simple configuration via EEPROM or from MCU
