Microchip adds independent peripherals to PIC32

By Nick Flaherty

Microchip has launched its first family of PIC32 microcontrollers with periperhals that can run independently of the core. This is a big step, as it helps to reduce power and simplify the development and operation of nodes in the Internet of Things (IoT) .

The MIPS MicroAptiv-based PIC32MM family bridges the gap between the company’s popular PIC24F XLP and PIC32MX families. But what makes this more significant is that the new family is the first PIC32 to feature core independent peripherals, designed to offload the CPU for lower power and lower system design cost. The PIC32MM devices are supported by the Microchip MPLA Code Configurator (MCC) to help simplify and accelerate designs.

Today’s embedded applications targeting the Internet of Things (IoT), consumer, industrial control, and motor control require flexible MCUs that consume less power, are more cost effective and have smaller form factors. For applications demanding low power and longer battery life, the PIC32MM has sleep modes down to 500 nA. Applications with space constraints will benefit from the small 4x4 mm package options. The PIC32MM devices include core independent peripherals such as Configurable Logic Cells (CLC) and Multiple-output Capture Compare PWMs (MCCPs) which help enable sensorless BLDC motor-control applications.

To help accelerate evaluation and development, a new $25 PIC32MM processor plug-in module is available (MA320020), which plugs into the $130 Explorer 16 Development Board (DM240001). The entire family of PIC32MM devices is supported by the Microchip MPLAB ecosystem including MPLAB X IDE and XC32 compiler. The MPLAB Code Configurator, a plug-in to the MPLAB X, helps with easy peripheral set-up, device configuration and pin mapping.

The PIC32MM family is available in mass production today in 20-pin QFN and SSOP; 28-pin µQFN, QFN, SOIC, SSOP, SPDIP; 36-pin QFN; and 40-pin uQFN packaging. Devices are available in 16 KB, 32 KB, and 64 KB Flash variants.
