The TMC454 is a high-end motor 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 function 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 motion control jobs. In many applications, the TMC454 reduces the time time-to-market, and it saves costs for software development and hardware engineering. The TMC454 turns stepper motors into easy to use peripherals!
The TMC454 is upwards function compatible to its predecessor TMC453.
