Low-Power Microcontrollers and Microprocessors

The Right Combination of Battery-Friendly Features for Your Low-Power Applications

Minimizing power consumption in battery-powered  wearables, wireless sensor networks, and other Internet of Things (IoT)-enabled smart devices is essential. If you need to reduce the operating power in your project, discover how our 8-, 16- and 32-bit eXtreme Low Power (XLP) PIC® microcontrollers (MCUs), 8-bit AVR® and 32-bit SAM MCUs with picoPower® technology, and 32-bit low-power SAM microprocessors (MPUs) offer the right combination of features to meet your design’s specific requirements.

Microchip’s low-power technology enables MCU sleep currents down to 9 nA and run currents down to 25 μA/MHz.

Microchip’s low-power technology enables MCU sleep currents down to 9 nA and run currents down to 25 μA/MHz

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

Consistent low-power features, peripherals and tools for ease of migration

8-bit Low Power MCUs

  • 8-bit PIC and AVR MCUs – industry’s lowest-power microcontrollers
  • eXtreme Low Power (XLP) and picoPower technologies
  • Sleep currents as low as 9 nA with power-efficient wake-up sources and run currents down to 30 μA/MHz
  • Integration of Core Independent Peripherals (CIPs) enables application functions while minimizing CPU overhead, system latency and power consumption
  • Low-power features include Peripheral Module Disable, Idle Mode and Doze Mode
  • Widest operating range: 1.6V to 5.5V

16-bit Low-Power MCUs

  • Large portfolio of devices with Flash options ranging from 4 KB to 1 MB and pin counts of 8 to 121 pins
  • Sleep currents as low as 30 nA with flexible wake-up sources and run currents down to 150 μA/MHz to enable power-efficient applications
  • Flexible, integrated Core Independent Peripherals (CIPs) such as Crypto Engine, Configurable Logic Cells (CLC), Real-Time Clock/Calendar (RTCC), Pulse-Width Modulators (PWMs) and Peripheral Trigger Generator (PTG) designed to take the load off the CPU and reduce the overall energy requirements
  • More space and BOM cost savings with our small-footprint packaging options

32-bit Low-Power MCUs

  • Combines ultra-low power with Flash and SRAM that are large enough to run both the application and wireless stacks
  • Chip-level tamper resistance and Arm TrustZone® to protect low-power applications from security vulnerabilities
  • Integrate peripherals and design techniques used to minimize power consumption in real-world battery-powered applications
  • Under 25 μA/MHz active and 100 nA sleep current, 1.2 μS wakeup time
  • Highest certified ULPMark™ score for any Arm Cortex-M23 or Arm Cortex- M0+ class device; ULPMark score of 410 on SAM L11
  • Innovative SleepWalking peripherals and Event System

32-bit Low Power MPUs

  • 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)
