The TMC429 is a miniaturized low cost, 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 TMC429 is fully downwards compatible to the TMC428.
The TMC429 connects to the recent coolStep™ drivers (TMC260, TMC262 and TMC389) via Step- & Direction signals (S/D) or to the classic TRINAMIC drivers TMC236, TMC239, TMC246 and TMC249 via SPI™. The communication with the host microcontroller is done with an extra SPI™ interface. The host just needs to do high-level control tasks, e.g. giving the command: Drive motor 2 to position 1000. The TMC429 automatically calculates the motion ramp based on velocity and acceleration parameters.
