32-bit XLP PIC® and SAM Low-Power Microcontrollers

Reduce power consumption while maintaining performance.

Microchip offers a broad range of ultra-low-power and low-power 32-bit MCUs that balance power consumption and performance to meet the needs of power-constrained applications seeking high levels of functionality. The portfolio ranges from the smallest SAM D ARM® Cortex®-M0+ based MCUs, to the ultra-low-power SAM L ARM Cortex-M0+ based MCUs, to higher-performing SAM ARM Cortex-M4F-based MCUs and the PIC32MX XLP family of MCUs, each catering to diverse low-power embedded design needs.

Benefits of 32-bit SAM picoPower and 32-bit PIC XLP MCUs

Low Power Sleep modes and operating voltage

  • Active mode current down to 25 μA/MHz
  • Deep sleep current down to 100 nA
  • SRAM retention (40KB) down to ~1 μA
  • 1.2 μs wake-up time from idle state
  • Fully operational down to 1.62V while still maintaining all functionality, including analog functions
  • Highest certified ULPMark score for any ARM® Cortex®-M23 or ARM® Cortex®- M0+ class device, ULPMark Score of 405 on SAM L10

Flexible and Advanced Peripherals

  • Event system - CPU independent inter-peripheral communication offloading and minimizing CPU active time
  • Sleepwalking with dynamic power gating - Allows MCU to be put into deep sleep and wake up only upon a pre-qualified event
  • Chip-level tamper resistance and ARM® TrustZone® to protect low power applications from security vulnerabilities
  • Low-power SERCOM and Timer counters
  • Enhanced Peripheral Touch Controller (PTC) - 4 μA standby with multi-button, wake on touch. Highly responsive with superior water tolerance and excellent noise immunity
