Microchip PIC32MM0256GPM028T-I/ML

The eXtreme low power PIC32MM GPM family extends Microchip's lowest power and most cost-effective family of 32-bit PIC32 microcontrollers by adding USB and ECC memory up to 256KB. The PIC32MM GPM family provides a smooth upward migration path to the PIC32MM GPL family customers who want more memory and pins while also providing a cost-effective migration path for customers who need higher performance and lower power in compact packages as small as 4x4mm.

Benefits:

• eXtreme low power in compact packages
• PIC32MM GPM devices offer sleep modes down to 650 nA 
• USB Connectivity
• PIC32MM GPM family provides increased connectivity by integrating crystal-less USB 2.0 host, device, and OTG support
• The USB module also features a dedicated DMA for increased efficiency
• Core Independent Peripherals
• Designed to offload the CPU and increase efficiency, this eXtreme low power family features a rich set of core independent peripherals, such as a 4-Channel Hardware DMA with Automatic Data Size Detection, a CRC Engine, Hardware Real-Time Clock and Calendar (RTCC), Configurable Logic Cells (CLC) and Multiple-output Capture Compare PWMs (MCCPs)

Supported by the popular MPLAB Code Configurator (MCC) tool, setting up pin assignments, peripheral modes and application stacks have never been easier helping customers bring their design to the market faster than ever before.

This family’s eXtreme low power, large memory and a versatile peripheral set, make it ideal for:

• Entertainment/Gaming Industry (USB digital audio noise cancellation headsets, Gaming controllers, USB power delivery management, Drone controllers)
• IoT Sensor Nodes (Environmental monitoring, Sensor control, Smart remotes)
• Portable Medical Instruments(Home healthcare, Fitness devices)
• Automation Control Applications(Smart locks, Smart garage door openers, Home security control panels)
