The STM32L100RBT6ATR from STMicroelectronics is a low-power ARM Cortex-M3 microcontroller designed for energy-efficient embedded control. Operating from 1.8V to 3.6V, it delivers 32MHz performance with 128KB flash and 16KB SRAM. The device integrates an LCD controller, DMA, PWM, and multiple watchdog timers, making it suitable for metering, medical, and industrial applications. Its 64-LQFP package supports compact PCB layouts while maintaining robust thermal performance.

  • Ultra-low-power operation: 1.8V supply and optimized sleep modes extend battery life in portable devices.
  • Integrated LCD controller: Eliminates external display driver ICs, reducing BOM cost and board space.
  • High integration: DMA, PWM, and brown-out detection reduce external components and improve system reliability.
  • Proven ecosystem: Full STM32 toolchain and HAL libraries accelerate firmware development.

Portable Medical Devices

The low 1.8V operation and integrated LCD controller enable compact, battery-powered glucose meters and pulse oximeters with clear displays.

Smart Meters

With 128KB flash and DMA, it efficiently handles data logging and communication protocols in gas and water meters, while the low-power modes extend battery life.

Industrial Sensors

The 32MHz Cortex-M3 core and multiple PWM channels allow precise control and signal conditioning in pressure and temperature transmitters.

Home Automation Panels

Its LCD driver and rich GPIO set make it ideal for thermostat displays and keypad interfaces, supporting multiple I/O states with brown-out protection.

Battery-Powered Data Loggers

The 16KB SRAM and DMA reduce CPU overhead, enabling continuous sensor sampling with minimal power draw in remote monitoring systems.

Access Control Systems

Integrated POR and WDT ensure reliable operation in keypads and card readers, while the wide voltage range accommodates varying power supplies.
