Microchip adds GPM models to eXtreme low power PIC32MM microcontroller family

Particularly suitable for digital audio applications, gaming and entertainment devices, internet of things (IoT) sensor nodes and portable medical devices, the PIC32MM GPM microcontrollers (MCUs) have been introduced by Microchip.

The PIC32MM GPM eXtreme low power (XLP) MCUs feature large memory in small packages, says Microchip, to provide ample battery life for space-constrained applications. The GPM MCUs include several connectivity options, Core Independent Peripherals (CIPs) and feature-rich development boards.

The XLP PIC32MM GPM MCUs enables developers to minimise power consumption, board space and development time, claims Microchip. The MCUs provide power-saving options, such as sleep modes with current consumption as low as 650nA with random access memory (RAM) retention, to extend battery life in portable applications. The PIC MCUs are available with up to 256kbyte of error correction code (ECC) flash and 32kbyte of RAM, providing ample space for application code and communication stacks, reassures Microchip.

The XLP PIC32MM CPM MCUs are available in a variety of pin-count options ranging from 28 to 64 pins in compact packages, as small as 4.0 x 4.0mm with 28 pins; 5.0 x 5.0mm with 36 pins; and 6.0 x 6.0mm with 48 pins.

The PIC32MM GPM family of MCUs integrates CIPs such as direct memory access (DMA), configurable logic cells (CLC) and a 12-bit analogue to digital converter (ADC). These allow the system to accomplish tasks in hardware while freeing-up the central processing unit (CPU) to do other tasks or to go to sleep. Leveraging these hardware-based CIPs improves execution efficiency while maintaining system flexibility and lowering overall power consumption.

These MCUs also include a crystal-less universal serial bus (USB) device/host/on-the-go (OTG) and I2S functionality, crucial for USB audio applications and communication gateways. This accurate on-chip USB oscillator eliminates the need for an external crystal or oscillator, says Microchip, to reduce overall system bill of material (BoM) cost and board real-estate associated with USB applications.

The PIC32MM GPM family is supported by Microchip’s MPLAB Code Configurator (MCC) tool. MCC makes it easy to configure the USB stack, pin assignments and peripherals, to significantly accelerate development time, says Microchip. The MCUs are also supported by Microchip’s MPLAB X integrated development environment (IDE) ecosystem and XC32 compiler.

The PIC32MM USB Curiosity Development Board is integrated with a programmer/debugger for development. The board also features two MikroElektronika mikroBUS interfaces that enable support for more than 300 click boards, a USB Micro B connector and two X32 interfaces that enable access to the PIC32 audio codec daughtercard.

In addition, the PIC32MM processor Plug-in Module, which plugs into the Explorer 16/32 Development Board ecosystem, is available to begin development with easy evaluation.

The PIC32MM GPM devices are available in 64, 128 and 256kbyte flash variants with 28-, 36-, 48- and 64-pin packaging options. All device variants are currently available for orders and samples, with the 28-pin UQFN available early next quarter.
