Microchip Technology Inc. has expanded its eXtreme Low Power (XLP) technology with the release of its PIC32 microcontroller family for 32-bit PIC32MX products.

According to Microchip, the PIC32MX1/2 XLP offers current PIC32MX customers an easy migration path to achieve higher performance at much lower power, enabling both increased functions and longer battery life in portable applications. The PIC32MX1/2 XLP family improves performance in small pin-count devices with little code rework for existing customers, Microchip added.

Microchip noted that its XLP technology is designed for wearable technology, wireless sensor networks and other smart connected devices and offers low current operating modes for Run and Sleep, where extreme low-power applications spend 90–99% of their time. XLP technology will enable sleep and deep sleep shutdown states on the PIC32MX1/2 XLP devices, enabling Deep Sleep currents down to 673nA. The devices offer over 40% higher performance than the existing PIC32MX1/2 portfolio while reducing average run currents by 50%, Microchip said.

The PIC32MX1/2 XLP family offers a range of memory configurations with 128/256KB Flash and 32/64KB of RAM in packages ranging from 28 to 44 pins. They also include a set of peripherals including I2S for digital audio, 116 DMIPS performance for executing audio and advanced control applications, a 10-bit 1Msps 13-channel ADC and serial communications peripherals. The PIC32MX2 series also supports USB-device, host and OTG functionality.

In addition to the hardware peripheral features, the series is supported by Microchip’s MPLAB Harmony Software Development Framework, which integrates the license, resale and support of Microchip and third-party middleware, drivers, libraries and RTOSs.
