Low-power PIC microcontrollers
19 July 2017
DSP, Micros & Memory
Microchip announced new PIC32MM ‘GPM’ microcontrollers (MCUs) featuring large memory in small packages to provide ample battery life for space-constrained applications. With the inclusion of several connectivity options, core independent peripherals and feature-rich development boards, these parts are well suited for digital audio applications, gaming/entertainment devices, 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 RAM retention. They 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 MCUs are available in a variety of pin-count options ranging from 28 to 64 pins in compact packages, as small as 4 x 4 mm with 28 pins; 5 x 5 mm with 36 pins; and 6 x 6 mm with 48 pins to optimise the overall design footprint.
The GPM family integrates core independent peripherals such as direct memory access, configurable logic cells and a 12-bit analog-to-digital converter. These MCUs also include a crystal-less USB device/host/On-the-Go (OTG) and I2S functionality, crucial for USB audio applications and communication gateways. An accurate on-chip USB oscillator eliminates the need for an external crystal or oscillator.
