Microchip Technology PIC32 microcontroller range

Microchip Technology has launched a series of low pin count, 32-bit PIC32 microcontrollers that provide 61 DMIPS of performance in packages of 5 mm.

The PIC32 MX1 and MX2 MCUs are the smallest and lowest-cost PIC32 microcontrollers, and are said to be the first PIC32 MCUs to feature dedicated audio and capacitive-sensing peripherals.

The devices also feature USB on-the-go capabilities, making them suitable for developing audio accessories and other applications in the consumer, industrial, medical and motor vehicle 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 RAM, two I2S interfaces for audio processing, an integrated hardware peripheral for adding mTouch capacitive touch-buttons or advanced sensors, and an 8-bit parallel master port (PMP) interface for graphics or external memory.

Additionally, the devices feature an on-chip 10-bit, 1 Msps, 13-channel analog-to-digital converter and serial-communications peripherals, with the PIC32 MX2 MCUs adding USB OTG.

The MCUs are offered in packages from 28 to 44 pins. Further easing the design effort is Microchip’s Peripheral Pin Select feature, which allows developers to ‘remap’ most of the chip’s digital-function pins, making layout and design modifications significantly simpler.
