Target microcontrollers mount on plug-in modules to supportquickly changing the target MCU. Available microcontrollers for the DEMOAC include; theColdFire V1 MCF51AC256, and the MC9S08AC128/60/16. Application development on theDEMOAC 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. An80-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. TheDEMOACEX connects to the DEMOAC through the 80-pin MCU_PORT connector.MCU Modules:• MCF51AC256, 80LQFP• 256K bytes FLASH• 32K bytes RAM• ColdFire V1 Core• 50.3 MHz bus• MC9S08AC128/60/16• 128K/60K/16K bytes FLASH• 8K/2K/1K bytes RAM• HCS08 CoreDEMOAC Features:• Integrated, USB BDM• ON/OFF Power Switch• Power Input Select Option Header• On-board 5V regulator• Power from USB BDM• Optional Power Sourced toConnector J1• 4MHz XTAL Oscillator• 3-axis accelerometer• LEDs – 4 User, 1 Power, 1 Reset• Push button switches – 4 user, 1 Reset• 5K ohm POT• Jumpers to disconnect User Features• 80-pin MCU PORT provides access to MCU signals• 4 20-pos pin-headers support plug-in MCU modules• IIC Termination Select HeaderDEMOAC Board Size: 5.0” x 4.0 |
