The STMicroelectronics STM8S207CBT6 is an 8-bit microcontroller with a 24MHz STM8 core, 128KB flash, and 6KB RAM. It operates from 2.95V to 5.5V, making it compatible with legacy 5V designs. The 48-LQFP package offers ample I/O for control applications. Integrated features include brown-out detection, POR, PWM, and WDT, ensuring reliable operation in industrial and consumer environments.

  • High flash density (128KB): Supports complex firmware and data storage.
  • 5V tolerant I/O: Direct interface with sensors and actuators without level shifting.
  • 24MHz performance: Adequate for real-time control loops.
  • Robust safety features: Brown-out detect and WDT prevent system failures.
  • Cost-effective 8-bit solution: Lower cost than 32-bit MCUs for simple tasks.

Industrial Automation

24MHz STM8 core and 128KB flash handle PLC I/O modules and sensor interfaces with deterministic timing.

Power Tools

5V operation and PWM support brushless motor control in drills and saws, with WDT for safety.

Smart Meters
