TMC428
Description
3-axis economic miniature microstepping stepper motion controller
The TMC428 is a miniaturized low cost, but 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 TMC428 connects to the TRINAMICs SPI™ drivers (TMC236,TMC239,TMC246 and TMC249) or to Step-/direction drivers. A second SPI™ interface allows communication with a host microcontroller. The host microcontroller just needs to do high-level control tasks, e.g. giving the command: Drive motor 2 to position 1000. The TMC428 then automatically calculates the motion ramp based on velocity and acceleration parameters.
The TMC423 adds encoder functionality as well as step- direction impulse forming to the TMC428. Evaluation Boards, application notes, spreadsheets for parameter calculation, C code examples and schematics are available in order to support short design-in times.
TMC 428 - The small but intelligent Controller:
* Miniaturized low-cost 3 axes motor controller
* High-performance micro stepping
* SPI interface with easy-to-use protocol
* On-the-fly alteration of position set point

TMC454
Description
1-axis stepper motion controller with S-ramps and encoder feedback
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.
