Microchip Technology Inc. recently 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 by 5 mm. The PIC32 MX1 and MX2 MCUs, the smallest and lowest-cost PIC32 MCUs, are the first in the family to feature dedicated audio and capacitive-sensing peripherals. The devices also feature USB On-the-Go (OTG) capabilities.
Rated for operation up to 105°C, the PIC32 MX1 and MX2 MCUs include up to 128 kbytes of flash memory and 32 kbytes 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. In addition, the new devices feature an on-chip 10-bit, 1 Msample/s, 13-channel analog-to-digital Converter, and serial-communications peripherals. The MCUs are offered in packages from 28- to 44-pins. Pricing starts at $2.14 each, in 10,000-unit quantities.
