Evaluation boards for HC12 / HC912


We designed the evaluation boards and starterkits for quick and easy software development or testing for each special controller. You could also use them for quick design of hardware prototypes e.g. breadboard construction without the need of special SMD boards.

The BDM-Interface provides the ability of software debugging or In-Circuit-Programming of the Controllers Flash Memory.

Main specifications of the boards:

  • Uniform pinout of all boards for easy fit on test hardware or prototypes (2,54mm-grid)
  • Dimensions ca. 52 x 57,4mm
  • Oscillators and quartz crystals in different structural shapes could be used
  • Reset-switch
  • You could optional assemble: voltage regulator, 2 LEDs
  • We used special long Pinheads for easy connection of e.g. oscilloscope, logic analyser or test hardware on each side of the board
