The PIC32MX family processors are complex systems-on-a-chip that contains many features. PICMX32MX is a high-performance RISC CPU, which can be programmed in 32-bit and 16-bit modes, and even mixed modes. The PIC32MX MCU contains a high-performance interrupt controller, DMA controller, USB controller, in-circuit debugger, high performance switching matrix for high-speed data accesses to the peripherals, on-chip data RAM memory, which hides the latency of the Flash,gives zero Wait state equivalent performance.
