1 Features

The TMC428 is a miniaturized high performance stepper motor controller. It controls up to three 2-

phase stepper motors. All motors can operate independently. The TMC428 allows up to 6 bit micro

step resolution – corresponding to 64 micro steps per full step – individually selectable for each motor.

Once initialized, it performs all real time critical tasks autonomously based on target positions and

velocities, which can be altered on-the-fly. So, an inexpensive microcontroller together with the

TMC428 forms a complete motion control system. The microcontroller is free to do application specific

interfacing and high level control functions. Both, the communication with the microcontroller and with

one to three daisy chained stepper motor drivers take place via two separate 4 wire serial peripheral

interfaces. The TMC428 directly connects to SPI^TM*smart power stepper motor drivers.
