    Kit Overview

    The DEMO9S08QG8DEMO9S08QG8 is a demonstration board for the MC9S08QG8MC9S08QG8 microcontroller. Development of application code is quick and easy with the  integrated USB-to-BDM interface, CodeWarriorTM Development Studio, and software examples. A 32-pin connector allows connecting the DEMO9S08QG8 board to an expanded evaluation environment.


    The S08QG Family of microcontrollers provide a wide variety of serial interfaces and peripherals, normally found in higher-end devices, all in a small package. Featuring low-power S08 8-bit architecture, S08QG devices are a perfect fit for battery-powered devices.


    The operating modes of the MC9S08QG8/4 are described below. Entry into each mode, exit from each mode, and functionality while in each mode are described.


    • Active background mode for code development
    • Wait mode:
      • CPU halts operation to conserve power
      • System clocks running
      • Full voltage regulation is maintained
    • Stop modes: CPU and bus clocks stopped
      • Stop1: Full powerdown of internal circuits for maximum power savings
      • Stop2: Partial powerdown of internal circuits; RAM contents retained
      • Stop3: All internal circuits powered for fast recovery; RAM and register contents are retained


    Key Applications:

    • Consumer - Small Appliances, Toys
    • Medical/Health Care - Vital Signs Monitors
    • Networking - Wireless Communications
