TMC454 pdf datasheet

Intelligent Motion Chip

The TMC454 is the direct successor?of the TMC453 and is 100% software compatible.

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.
