The STMicroelectronics STM8S208MBT6B is an 8-bit microcontroller featuring the STM8 core at 24 MHz. It provides 128 KB of flash memory and 6 KB of RAM, suitable for mid-range embedded applications. Operating from 2.95V to 5.5V, it supports both 3.3V and 5V logic. The device includes brown-out detection, POR, PWM, and WDT. Packaged in an 80-LQFP, it operates from -40°C to 85°C, making it versatile for consumer and industrial products.

  • High code density: 128 KB flash supports large applications without external memory.
  • Flexible voltage range: 2.95V-5.5V simplifies interfacing with legacy 5V peripherals.
  • Rich peripheral set: PWM, WDT, and brown-out detection reduce external component count.
  • Ample I/O: 80-pin LQFP offers extensive GPIO for complex control panels.
  • Cost-effective 8-bit performance: 24 MHz provides sufficient throughput for most control loops.

Home Appliance Control

The 128 KB flash stores complex washing machine cycles. The 5V operation directly interfaces with triac drivers for motor and heater control.

Industrial Automation I/O Modules

With 24 MHz speed, it processes digital inputs and drives relay outputs. The 80-pin LQFP provides ample GPIO for multi-channel I/O.

Power Supply Monitoring

Brown-out detection and POR ensure safe operation during power-up/down. The 2.95V minimum voltage allows 3.3V rail monitoring.

HVAC Thermostats

PWM outputs control fan speeds, while the 6 KB RAM stores user schedules. Its wide voltage range supports both battery and mains-powered designs.

E-bike Controllers

The 24 MHz core executes hall-sensor commutation for BLDC motors. The 128 KB flash accommodates torque mapping and safety algorithms.

Smart Meters

Integrated WDT ensures firmware reliability in long-term metering applications. The 80-pin package allows connection to multiple communication interfaces.
