DEMO9S12PFAME演示板是评估MC9S12P128 微控制器功能和应用的系统。DEMO9S12PFAME takes advantage of CodeWarrior? (which groups an editor, assembler, c compiler and debugger) and Freescale USB-BDM interface, that allows the download and debug of the user application in the microcontroller's FLASH memory.
特性：
A MC9S12P128 microcontroller (in 80-Pin QFP package, already programmed with a demo application)
A 4 MHz crystal.
A 12 V DC power supply input connector.
Power input selection jumper for selecting the input voltage source:
12 V DC input connector
USB connector.
A built-in USB-to-BDM circuitry which allows the host PC to communicate with the microcontroller through a standard USB interface. USB 2.0 is fully supported. When using an external in-circuit debugger (via the "BDM" connector), the USB-to-BDM circuitry must be bypassed by removing the BKGD and RESET jumpers.
A Reset push-button connected to the MCU Reset pin.
A series of inputs:
Two push-buttons, together with jumpers to connect/disconnect them to/from the microcontroller.
Four DIP-switches, together with jumpers to connect/disconnect them to/from the microcontroller.
A potentiometer, together with a jumper to connect/disconnect it to/from the microcontroller.
A photocell, together with a jumper to connect/disconnect it to/from the microcontroller.
Four high-efficiency (low-current) LEDs together with jumpers to connect/disconnect them to/from the microcontroller.
An RS-232 channel connected to the microcontroller’s SCI serial communication interface, together with a jumper to select the RS-232 or LIN functionality (see point below)
Two LIN connectors sharing one LIN transceiver, together with jumpers for configuration
One CAN connector with high-speed CAN transceiver, together with jumpers for configuration
