Features

The TMC332 is a high resolution micro step sequencer with integrated sine wave look-up table and

integrated PWM units. The TMC332 can control both, 2-phase stepper motors and 3-phase stepper

motors. The TMC332 has two alternative step direction interfaces - a classical two wire step/direction

interface and a SPI step direction interface for the TMC428 driver chain. An Internal micro step

counter with programmable step width makes the handling of physical units comfortable.

Parameterizing the TMC428 and the TMC332 takes place over a common SPI micro controller

interface.
