The PIC32MX220F032B-I/SP is a 32-bit Microcontroller (up to 256kB flash and 64kB SRAM) with audio and graphics Interfaces, USB and advanced analog. The MIPS32? M4K? Processor Core is the heart of the PIC32MX1XX/2XX family processor. The CPU fetches instructions, decodes each instruction, fetches source operands, executes each instruction and writes the results of instruction execution to the destinations The MIPS32 M4K processor core contains several logic blocks working together in parallel, providing an efficient high-performance computing engine.
