Features

• 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
