Microchip announced a new series of low pin-count 32-bit PIC32 microcontrollers (MCUs) that provide 61 DMIPS of performance, in packages as small as 5 x 5 mm, for space-constrained and cost-sensitive designs. The 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. They include a host of additional 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 32 KB of Flash and 8 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.
The new devices also feature an on-chip 10-bit, 1 MSps, 13-channel ADC, 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 5 mm and a 0,5 mm pitch, to the PIC32 MCU product line. Microchip’s Peripheral Pin Select feature further eases design effort by allowing developers to ‘remap’ most of the chip’s digital function pins to simplify layout and design modifications.
For easy migration, the PIC32 MX1 and MX2 devices are compatible with Microchip’s 16-bit PIC24F product line, and are supported by the MPLAB X IDE which also supports all of Microchip’s 8-, 16- and 32-bit MCUs.
