The STM8AL3168TCY from STMicroelectronics is a low-power 8-bit microcontroller built on the STM8 core. It operates at up to 16MHz with a supply voltage range of 1.65V to 3.6V, making it ideal for energy-sensitive designs. The device provides 32KB of flash memory and 2KB of RAM in a compact 48-LQFP package. Integrated features include brown-out detection, DMA, PWM, and a watchdog timer, ensuring robust operation across -40°C to 125°C.
- Ultra-low voltage operation (1.65V) – enables direct battery or energy-harvesting power, reducing system complexity and cost.
- Extended temperature range (-40°C to 125°C) – ensures reliable performance in harsh industrial or automotive environments.
- Integrated DMA controller – offloads data transfer tasks from the CPU, improving real-time responsiveness and reducing power consumption.
- Compact 48-LQFP package – balances I/O count with board space, suitable for space-constrained designs.
Battery-Powered Industrial Sensors
The 1.65V minimum supply voltage allows operation directly from a single-cell battery or energy harvesting source, while the 16MHz STM8 core provides sufficient processing for sensor calibration and data logging.
Portable Medical Monitoring Devices
With a wide temperature range (-40°C to 125°C) and low power consumption, this MCU is ideal for wearable or handheld medical devices that must operate reliably in varying environmental conditions.
Smart Building Automation Controllers
The integrated DMA and PWM modules enable efficient control of lighting or HVAC actuators, while the 32KB flash can store complex control algorithms and calibration data.
Automotive Body Electronics
The extended temperature range and brown-out detection make it suitable for automotive interior modules such as window lift controllers or seat position memories, where voltage stability is critical.
Precision Agriculture Data Loggers
Low-voltage operation and robust reset circuitry ensure reliable data acquisition in remote field sensors, with the 2KB RAM buffering readings before transmission.
Industrial Process Control Loops
The PWM outputs and watchdog timer support closed-loop control for pumps or valves, while the 48-pin LQFP package offers enough I/O for multiple sensor inputs.
