MOTION C O N T R O L L E R

The TMC428 is a revolutionary miniaturized low cost and high

performance stepper motor controller for up to three motors.

It integrates all real time critical tasks in reliable, dedicated

hardware: An integrated motion ramp profile generator as well

as an adaptable microstep sequencer with microstep RAM table.

Advanced stop- and reference switch handling allows for precise

and fast referencing as well as on-the-fly position checking.

Automatic motor current control gives high motor dynamics

while saving energy. The interrupt output can generate precise

position pulses. The TMC428 directly connects to SPI™ drivers

or to step-/direction drivers. A second SPI™ interface allows

communication with a host microcontroller. The host microcon-

troller just needs to do high-level control tasks, e.g. giving the

command: Drive motor 2 to position 1000. The TMC428 then

automatically calculates the motion ramp based on velocity and

acceleration parameters. The TMC423 adds encoder functionality

to the TMC428. Evaluation Boards, application notes, spread-

sheets for parameter calculation, C code examples and schema-

tics are available in order to support short design-in times.
