Use a 4-layer printed circuit board with the VDD and GND pins connected directly to the power
and ground planes for the MCF5275.
See application note AN1259 System Design and Layout Techniques for Noise Reduction in
MCU-Based Systems.
Match the PC layout trace width and routing to match trace length to operating frequency and board
impedance. Add termination (series or therein) to the traces to dampen reflections. Increase the
PCB impedance (if possible) keeping the trace lengths balanced and short. Then do cross-talk
analysis to separate traces with significant parallelism or are otherwise "noisy". Use 6 mils trace
and separation. Clocks get extra separation and more precise balancing.
33uF, 0.1 μF, and 0.01 μF across each power supply

Power Supply
Refers to pin’s primary function. All pins which are configurable for GPIO have a pullup enabled in GPIO
mode with the exception of PBUSCTL[7], PBUSCTL[4:0], PADDR, PBS, PSDRAM.
If JTAG_EN is asserted, these pins default to Alternate 1 (JTAG) functionality. The GPIO module is not
responsible for assigning these pins.
