32-bit PIC MCUs Improve Performance & Battery Life In Portables


Microchip has announced its latest 32-bit PIC32 microcontrollers which are said to offer higher performance at much lower power than previous products. Featuring eXtreme Low Power (XLP) technology, the new PIC32MX1/2 XLP MCUs allow current users of the PIC32MX to upgrade to higher performance and longer battery life in portable products with only minimal code modification, according to Microchip.

The manufacturer stated that with XLP technology, the PIC32MX1/2 XLP devices will offer Deep Sleep mode currents down to 673 nA, over 40 percent higher performance than the existing PCI32MX1/2 portfolio, and reduce average run currents by 50 percent.

Designed for wearable technology, wireless sensor networks and other smart connected devices, XLP technology is claimed to offer low current operating modes for Run and Sleep, where extreme low-power applications spend 90 to 99 percent of their time.

The new MCUs are available in a range of memory configurations with 128/256 KB Flash and 32/64 KB of RAM in packages ranging from 28 to 44 pins.


Also included are a diverse set of peripherals at a low cost such as I2S for digital audio, 116 DMIPS performance for executing audio and advanced control applications, a 10-bit 1 Msps 13-channel ADC and serial communications peripherals. The PIC32MX2 series also supports USB-device, host and OTG functionality.

Furthermore, the series is supported by Microchip’s MPLAB Harmony Software Development Framework, which simplifies development cycles by integrating the license, resale and support of Microchip and third-party middleware, drivers, libraries and RTOSs. MPLAB Harmony offers access to software support for digital audio and Bluetooth applications.

“The PIC32MX family was a natural fit to include XLP technology,” said Rod Drake, vice president of Microchip’s MCU32 division. “The family has already been successful in the wearable market with a vast array of software and support. Customers will be able to easily enjoy the benefits associated with this latest expansion.”

Development support for the new MCUs include PIC32MX XLP Starter Kit, a PIC32MX254F256 PIM for Explorer 16 and a PIC32MX274F256 PIM for Bluetooth Audio Development Kit.

Parts are available today in 10,000 unit quantities. For more information about PIC32MX1/2 XLP, visit: http://www.microchip.com/PIC32MX_XLP_Main4380
