The STM8L151M8T6 from STMicroelectronics is an ultra-low-power 8-bit MCU with a 16MHz STM8 core. It features 64KB flash, 4KB RAM, and operates from 1.8V to 3.6V. The 80-LQFP package provides ample I/O for peripheral-rich applications. Integrated brown-out detection, DMA, IR, PWM, and WDT make it a versatile choice for battery-powered and industrial systems.

  • Ultra-low-power architecture: Extends battery life in portable devices.
  • Integrated IR and DMA: Reduces external components for remote control and data transfer.
  • 64KB flash: Sufficient for complex application code and data logging.
  • Wide temperature range (-40°C to 85°C): Suitable for most commercial and industrial settings.

Portable Medical Devices

The 1.8V operation and low-power STM8 core enable long battery life in glucose meters and pulse oximeters.

Smart Meters

64KB flash stores metering algorithms, while DMA and IR support efficient data communication in utility meters.

Consumer Electronics Remote Controls

Integrated IR transmitter and PWM allow direct IR signal generation for TV and AC remotes.

Industrial Sensor Interfaces

Brown-out detection and WDT ensure reliable operation in 24V industrial environments with noisy power lines.

Building Automation Thermostats

16MHz speed and PWM outputs drive heating/cooling actuators with precise timing control.

Wearable Fitness Trackers

Small 80-LQFP footprint and low-voltage operation support compact, energy-efficient wearable designs.
