PIC32MX1/MX2 Smallest, Lowest-Cost PIC32 Microcontrollers

Microchip's 32-bit MCUs (up to 128 KB Flash and 32 KB SRAM) with audio and graphics interfaces, USB, and advanced analog

Microchip's PIC32 “MX1” and “MX2” MCUs are the smallest and lowest-cost PIC32 microcontrollers, and are the first PIC32s to feature dedicated audio and capacitive-sensing peripherals. These MCUs include a host of additional useful features that make them suitable for applications in the consumer, industrial, medical and automotive markets.

Rated for operation up to 105°C, the PIC32 MX1 and MX2 MCUs include up to 128 KB of Flash, and 32 KB of SRAM; two I²S interfaces for audio processing; Microchip’s Charge Time Measurement Unit (CTMU) peripheral for adding mTouch™ capacitive touch buttons or advanced sensors; and an 8-bit Parallel Master Port (PMP) interface for graphics or external memory.
