INTEGRATED CIRCUITSMOTION CONTROLLER INFO MAIN CHARACTERISTICS www.trinamic.com – for detailed information and datasheets TMC 428 Three Axis Stepper Motor Controller with Integrated Sequencer The TMC428 is a revolutionary miniaturized low cost and 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 directly connects to SPI™ drivers or to step-/direction drivers. A second SPI™ interface allows communication with a host microcontroller. The host microcon troller 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 to the TMC428. Evaluation Boards, application notes, spread sheets for parameter calculation, C code examples and schema- tics are available in order to support short design-in times. unique minaturized stepper motor controller realized as low power 0.35µ CMOS device up to three stepper motors up to 64 times microstepping full step frequencies up to 20 kHz alteration of parameters at any time driver status information read back for µC power down mode ideally suited motor drivers are TMC236, TMC239, TMC246 and TMC249 INTERFACE SPI™ µC interface easy-to-use protocol for µC serial 4-wire driver interface (SPI™) step-/direction output ELECTRICAL DATA 3.3V or 5V operation CMOS / TTL compatible IOs PACKAGE miniature SSOP16 package SO24 package available RoHS compliant ORDER CODE DESCRIPTION TMC428-I 3-axis controller SSOP16-package TMC428-PI24 3-axis controller SOP24-package TMC428A-EVAL Evaluation board for TMC428, TMC246 and TMC249 with stallGuard™ 10 mm TMC428 RAM Interrupt controller serial µC interface Ramp- Pulse- generator serial Driver interface 3,3..5V DC SPI to µC CLK Microstep- Controller (incl. sequencer) SPI to driver SPI to driver SPI to driver REF 1,2,3
