ColdFire V1 MCF51AC256, and the MC9S08AC128/60/16. Application development on the DEMOAC is quick and easy with the integrated USB-BDM, sample software tools, and exam- ples. An optional BDM_PORT port is also provided to allow use of an external BDM cable. An 80-pin MCU_PORT connector provides access to all IO signals on the target MCU.
DEMOAC Top Silk GETTING STARTED To get started quickly, please refer to the DEMOAC Quick Start Guide. This quick start will il- lustrate connecting the board to a PC, installing the correct version of CodeWarrior Develop- ment Studio, and running a simple program.
POWER The DEMOAC may be powered from the integrated USB BDM, an on-board voltage regulator, or from the MCU connector at J1. Alternatively, the DEMOAC may be configured to provide power to external circuitry connected to the MCU connect J1.

MCU. Refer to the target device Reference Manual for further details. TIMING The DEMOAC board provide a 4Mhz oscillator timing source for use with the target MCU. The OSC_SEL option header allows this input to be disconnected if necessary. In default configu- rations, the OSC_SEL option header is not installed and cut-traces provide the default connec- tions.
2 0 0 8 Communications The DEMOAC board provides 2 UART ports, 1 IIC port, and 1 CAN port. Serial RS-232 com- munications is support through the integrated BDM. Access to each MCU UART is also avail- able at connector J1. RS-232 translation is not provided on signals to connector J1.
