MC9S12DP256 Based Target Board

This is a simple MC9S12DP256 carrier board designed to be low cost, versatile and easy to build. It measures 3.6 by 3.2 inches and brings out all 112 pins of the MC9S12DP256 to 4 headers in order to be expanded in an easy way. It includes area for a crystal, PLL’s loop filter components, bypass caps, mode select jumpers, power connector, voltage regulator and expanded BDM connector (mode select control from POD interface, compatible with the Motorola’s 6 pins BDM connector). Here you can see part of the schematic corresponding to the BDM interface:

The figures below show the layout for the components, the top and the bottom side of the PCB.
