1 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.
