Microchip unveils smallest, lowest cost PIC32 mcus

1 min read

Microchip has announced a series of 32bit PIC32 microcontrollers that it says are the smallest and lowest cost of their kind, and the first to feature dedicated audio and capacitive sensing peripherals.

According to the company, the PIC32 MX1 and MX2 mcus provide 61DMIPS of performance in packages as small as 5 x 5mm and include features that make them suitable for applications in the consumer, industrial, medical and automotive markets. The devices include up to 32KB of Flash and 8KB of sram, two I2S interfaces for audio processing, Microchip's charge time measurement unit (ctmu) peripheral for adding mTouch capacitive touch buttons or external memory. The new devices also feature an on chip 10bit, 1Ms/s, 13channel a/d converter as well as USB 2.0 and serial communications peripherals. The mcus introduce eight new packages from 28 to 44 pins with sizes down to 5 x 5mm and a 0.5mm pitch to the company's PIC32 mcu range. Microchip says its Peripheral Pin Select feature further eases design effort by allowing developers to 'remap' most of the chip's digital function pins. Both devices are compatible with Microchip's 16bit PIC24F product line, and are supported by the MPLAB X IDE development environment which also supports all of Microchip's 8, 16 and 32bit mcus.
