The STMicroelectronics STM32L051R6 is an ultra-low-power ARM Cortex-M0+ MCU with 32KB flash and 8KB RAM. Running at 32MHz with 1.65-3.6V supply, it includes DMA, I2S, brown-out detect, POR, PWM, and WDT in a 64-TFBGA package.

  • Ultra-low power for battery-operated devices.
  • ARM Cortex-M0+ ecosystem with broad tool support.
  • 1.65V minimum voltage enables single-cell operation.
  • DMA and I2S for efficient data streaming.

IoT Edge Nodes

Ultra-low power Cortex-M0+ with 32KB flash and 8KB RAM runs sensor protocols at 32MHz.

Wearable Health Monitors

1.65V operation and DMA enable continuous biosignal sampling with minimal power.

Smart Building Sensors

I2S interface supports audio capture; PWM drives indicator LEDs.

Battery-Powered Data Loggers

Low voltage threshold and brown-out detect ensure reliable logging over years.

Portable Test Equipment

64-TFBGA package saves space; DMA handles ADC data without CPU intervention.

Metering Applications

Low power and wide temp range (-40 to 85°C) suit utility meters.
