Microchip Technology Inc. reports that its 32bit PIC32MX1/MX2 series of MCUs achieve performance of are 25 per cent faster than previous MCUs at 50MHz or 83DMIPS.

The series includes the company's smallest MCUs measuring 5mm x 5mm x 0.5mm pitch. It also includes the lowest-cost PIC32 MCUs. Some of the devices have up to 128K Flash and 32K RAM. They integrate a hardware module for adding mTouch capacitive-touch buttons or advanced sensors, an 8bit Parallel Master Port (PMP) interface for graphics or external memory, a 10bit 1MSps 13-channel Analogue-to-Digital Converter (ADC), and serial communications peripherals. The MX2 series adds USB On-the-Go (OTG) capabilities.

The PIC32MX1 and MX2 MCUs are targeted for low-cost applications in the consumer and automotive markets, such as consumer music-player docks, noise-cancelling headsets, clock radios, and entertainment-system sound bars, as well as touch screens with buttons and sliders, graphic displays and USB device/host applications. In the medical and industrial markets, applications include industrial-grade noise-cancelling headsets and medical/industrial displays with touch-sensing capabilities.

The MCUs are supported by the company's MPLAB X Integrated Development Environment (IDE), MPLAB XC32 Compiler for PIC32 (part # : SW006015, Rs.47,354.50 ($895)), MPLAB ICD 3 In-Circuit Debugger(part # DV164035, Rs.10,052.38 ($189.99)) and MPLAB REAL ICE In-Circuit Emulation System (part # DV244005, Rs.26,453.97 ($499.98)).

The PIC32MX1and PIC32MX2 MCUs are available now in 28-pin SOIC, SPDIP and SSOP packages; a 36-pin VTLA package; and 44-pin QFN, TQFP and VTLA packages. The series is available sampling and volume production, starting at Rs.92.06 ($1.74) each in 10,000-unit quantities.
