Can I replace my TMC26x with the newer TMC26xC?
The TMC26x family (including the TMC260, TMC261, TMC262, and TMC2660) have all moved to a newer process. These new IC's are given a "C" suffix (ex. TMC262 --> TMC262C).
This process change comes with a few improvements and changes. While the TMC26xC version has been designed to be downward compatible to the TCM26x for most applications, some applications, which originally have been designed to work near to some limiting values, might need careful checking.
Please reference our Migration Guide for more information on the impact of these changes and how to migrate to the C version for existing applications:
