PIC32MM microcontrollers, the lowest power and most cost-effective family of 32-bit PIC32 microcontrollers from Microchip Technology are now on sale at distributor Mouser Electronics. The PIC32MM family bridges the gap between Microchip’s PIC24F XLP and PIC32MX families, and is the first PIC32 to feature core independent peripherals, designed to offload the CPU for lower power and lower system design.

The microcontroller comprises flexible, cost-effective microcontrollers that consume minimal power and feature small form factors.

The devices are based on the microAptiv UC 32-bit core with 5-stage pipeline and a MIPS32-enhanced architecture, which are integrated with the compact microMIPS instruction set and a shadow register set to enable a 79 CoreMark score at 25MHz.

Additionally, the microMIPS ISA combines 16-bit and 32-bit instructions for compact code size.

The PIC32MM devices offer 64 Kbytes of flash memory and 8 Kbytes of RAM, two analogue comparators with input multiplexing, a 5-bit digital-to-analog converter (DAC), and a software-selectable 10/12-bit analog-to-digital converter (ADC).

For applications demanding low power and longer battery life, the devices feature sleep modes down to 500 nA, while retaining RAM. The microcontrollers include core independent peripherals — such as configurable logic cells (CLCs) and multiple-output capture compare PWMs (MCCPs) — which help enable LED dimming and sensorless brushless DC (BLDC) motor control applications.

The PIC32MM devices are supported by the Microchip MPLAB Code Configurator to help simplify and accelerate designs in embedded applications such as Internet of Things (IoT), environmental monitoring, fitness devices, industrial control, and portable medical devices.
