The STMicroelectronics STM8S208RBT3 is an 8-bit microcontroller with a 24MHz STM8 core. It provides 128KB flash and 6KB RAM in a 64-LQFP package. Operating from 2.95V to 5.5V, it includes PWM, WDT, and brown-out reset, making it a cost-effective solution for automotive and industrial control applications requiring extended temperature range.

  • Extended temperature range (-40°C to 125°C): Suitable for automotive and high-heat industrial environments.
  • Wide voltage range (2.95V-5.5V): Flexible power supply design, direct 5V logic compatibility.
  • 128KB flash memory: Ample space for complex firmware and data logging.
  • 24MHz STM8 core: Efficient 8-bit performance for real-time control tasks.
  • 64-pin LQFP: Compact footprint with sufficient I/O for peripheral-rich designs.

Automotive Body Electronics

With 125°C rating and 5V tolerant I/Os, manage window lifts, wiper control, and lighting modules in harsh under-hood environments.

Industrial Sensors & Transmitters

Use 24MHz STM8 core and 128KB flash for signal conditioning, linearization, and 4-20mA loop control with high reliability.

Home Appliance Control

Drive relays, buzzers, and LEDs in washing machines or dishwashers, with PWM for variable speed motor control and WDT for safety.

Power Management Units

Monitor voltage/current and control sequencing in server or telecom power supplies, leveraging brown-out reset and low power modes.

Building Automation (HVAC)

Implement thermostat control, fan speed regulation, and communication with external sensors over UART/I2C in a compact 64-LQFP.
