3.0
The MCU module is the heart of the PIC32MX3XX/4XX
Family processor. The MCU fetches instructions,
decodes each instruction, fetches source operands,
executes each instruction and writes the results of
instruction execution to the proper destinations.

• 5-stage pipeline
• 32-bit Address and Data Paths
• MIPS32 Enhanced Architecture (Release 2)
