for TMC246/TMC249 stepper driver IC family
The TMC454 is a high-end motion controller for all common 2-,
tion 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
