1 Overview
The MCF5225X Tower MCU Module (TWR-MCF5225X) is a low-cost evaluation, demonstration and
development board. The TWR-MCF5225X can operate stand-alone or as the main control board in a
Tower System with peripheral modules.
The following list summarizes the features of the TWR-MCF5225X:
• Tower compatible microcontroller module
• MCF52259 in an 144 LQFP package
• MC9S08JM60 based Open Source Debug (OSBDM) circuit
• 4 user controlled LEDs
• Four DIP Switches and two push buttons for user input
• Potentiometer
• MMA7260 three-axis accelerometer
• RS232 transceiver and 2x5 pin header
• Expansion via Primary Elevator connector
A block diagram for the TWR-MCF5225X is shown in the figure below.
