Low Power MCU and MPU Family Overview

As more wearables, wireless sensor networks, and other Internet of Things (IoT) enabled smart devices are getting powered from battery, minimizing power consumption is essential. To enable applications demanding low power, Microchip offers a portfolio of 8-bit eXtreme Low Power (XLP) PIC® and picoPower AVR® microcontrollers,16-bit XLP PIC24 microcontrollers, 32-bit XLP PIC32 and picoPower SAM Microcontrollers and 32-bit low power SAM microprocessors.


Microchip’s low power technology enables MCU sleep currents down to 9 nA and run currents down to 30 μA/MHz


Industry leading integrated analog, USB, LCD, and embedded security sensing peripherals with very low operating power

  • Innovative SleepWalking peripherals & Event System
  • The SAMA5D2 series delivers the lowest power consumption of any MPU in its class and the SAMA5D3 series is ideal for battery-operated applications.
  • Typical sleep current is 250 μA in retention mode with an ultra-fast 15 μs wake-up in ULP1 mode. Typical run current is 233 μA/MHz.
  • Unique SleepWalking feature enables peripherals to asynchronously wake-up from sleep in ULP1 mode, for example by activity on a communication line.
  • Back-Up Mode with battery supply pin maintains the RTC and preserves a 5 KB SRAM data and 256-bit register file. Typical back-up current is 4.5 μA. Optional DDR Self-Refresh Mode maintains external SDRAM contents (40 μA).
