FEATURES
The DEMOAC provides a platform supporting a line of Freescale microcontrollers which are
part of the Flexis Continuum. Target microcontrollers mount on plug-in modules to support
quickly changing the target MCU. Available microcontrollers for the DEMOAC include; the
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. An ex-
panded feature set, including an E-Field sensor, is provided on the DEMOACEX board. The
DEMOACEX connects to the DEMOAC through the 80-pin MCU_PORT connector.
