TMC457 DATASHEET (V. 1.16 / 2009-Nov-25)
4.4 Stepper Motor Driver Interface (TMC236, TMC239, TMC246, TMC249)
The direct TRINAMIC driver interface of the TMC457 allows the TRINAMIC drivers to be controlled by
the TMC457.
4.4.1
For high resolution micro stepping the TMC457 has an interface for dual SPI DAC LTC2602.
4.4.2
For low resolution micro stepping, a TRINAMIC driver can be connected directly via SPI without an
additional DAC. With this, one can drive with 16 times micro stepping.
