The CSMB12DT256 is a demonstration board for the MC9S12DT256 MCU. Application development is quick and easy with the TBDML compatible integrated USB BDM, sample software tools, and examples. An optional BDM_PORT port is also provided, but not populated in default configuration, to allow use of an external BDM cable. A 60-pin MCU Port connector provides access to all I/O signals on the target MCU.
