The TMC454 is a high-end motion controller for all common 2-,

3-, and 5-phase stepper motors. It provides encoder feedback for

high reliability or high position resolution drives. A large set of

motion control features is included on this IC. The various func-

tion blocks are hardwired and „ready-to-use“. All processes can

be serialized using the instruction based interface. A complete

linear & S-shaped ramp generation unit is integrated within the

TMC454. All dynamic parameters can be adjusted for a given

application in a very broad range. The CPU is relieved from all

time critical tasks like ramp calculation or microstep generation.

Thus CPU and software engineer can focus on higher level mo-

tion control jobs. In many applications, the TMC454 reduces the

time time-to-market, and it saves costs for software develop-

ment and hardware engineering. The TMC454 turns stepper

motors into easy to use peripherals!

The TMC454 is upwards function compatible to its predecessor

TMC453.
