New PIC32MM “GPM” microcontrollers are now available from Microchip. The eXtreme Low Power (XLP) devices feature large memory in small packages, providing ample battery life for space-constrained applications. With the inclusion of several connectivity options, Core Independent Peripherals (CIPs) and feature-rich development boards, the “GPM” MCUs are well suited for digital audio applications, gaming/entertainment devices, Internet of Things (IoT) sensor nodes and portable medical devices.
The devices provide power-saving options, such as sleep modes with current consumption as low as 650 nA with Random Access Memory (RAM) retention, to greatly extend battery life in portable applications. These PIC MCUs are available with up to 256 KB of Error Correction Code (ECC) Flash and 32 KB of RAM, providing ample space for application code and communication stacks. The new devices are available in a variety of pin count options ranging from 28 to 64 pins in compact packages as small as 4 × 4 mm with 28 pins, 5 × 5 mm with 40 pins and 6 × 6 mm with 48 pins to optimize the overall design footprint (more info).
