　　Microchip Expands Low-Cost, Small-Package 32-Bit PIC32 Microcontroller Family

　　Microchip Technology Inc. (Microchip Technology) announced at the Embedded World Conference in Germany that it has launched a new low-pin-count 32-bit PIC32 microcontroller (MCU) series, providing 61 DMIPS performance in packages as small as 5mm x 5mm, suitable for space-constrained and cost-sensitive designs. The PIC32 "MX1" and "MX2" MCUs are the smallest and lowest-cost PIC32 microcontrollers, and are also the first PIC32 MCUs with dedicated audio and capacitive sensing peripherals. The latest devices are also equipped with USB On-the-Go (OTG) capabilities, making them ideal for developing audio accessories and other applications in the consumer, industrial, medical and automotive markets.

　　The PIC32 MX1 and MX2 MCUs are rated for operation up to 105°C and feature up to 128 KB of flash and 32 KB of RAM, two I2S audio processing interfaces, an integrated hardware peripheral for adding mTouch™ capacitive touch buttons or advanced sensors, and an 8-bit parallel master port (PMP) for graphic display or connecting external memory. In addition, the new devices feature a 13-channel, 1 Msps on-chip 10-bit analog-to-digital converter (ADC) and serial communication peripherals; the PIC32 MX2 MCU also adds USB OTG functionality. These MCUs are available in 28- to 44-pin packages as small as 5mm x 5mm with a pin pitch of 0.5mm. Microchip's peripheral pin selection feature further simplifies design work by allowing developers to "remap" most of the digital function pins in the chip, making it easier to modify layout and design. The PIC32 MX1 and MX2 devices are compatible with Microchip’s 16-bit PIC24F product line for easy migration and are supported by MPLAB® X IDE, the unified development environment for all Microchip 8-, 16- and 32-bit MCUs.

　　“The expansion of our PIC32 MX1 and MX2 families gives our customers more options for seamlessly migrating their evolving designs,” said Sumit Mitra, vice president of Microchip’s High-Performance Microcontroller Products Division. “With 128K of Flash, 32K of RAM, the highest DMIPS per MHz of any 32-bit MCU, and packages as small as 28 pins, the PIC32 MX1 and MX2 MCUs enable designers to differentiate their products in the market while keeping their designs small and cost-effective.”
