Development Tool For Low-Cost Development System

The DEMOQE128 is a low-cost development system designed for demonstrating, evaluating, and debugging the Freescale MC9S08QE128 and MCF51QE128 microcontrollers. The board supports two interchangeable plug-in daughter cards to quickly evaluate the 8-bit S08 and 32-bit ColdFire V1 QE128 MCUs. Embedded Multilink circuitry on the DEMOQE128 board allows the microcontroller on the DEMOQE128 to be powered, programmed, and debugged via USB from the PC. In addition, the demo board contains an on-board logic analyzer and virtual serial port via USB to assist with rapid development.It also supports plug-in RF daughter cards for SMAC and 802.15.4.
