The STM8AF6223PDAX is an 8-bit STM8A microcontroller from STMicroelectronics, featuring 8KB flash and 1KB RAM. It operates from 3V to 5.5V at 16MHz, with brown-out detection, POR, PWM, and WDT. The 20-TSSOP package is ideal for cost-sensitive automotive and industrial applications.

  • Wide voltage range (3V-5.5V): Directly interfaces with 5V logic and sensors.
  • Integrated brown-out detection: Prevents system corruption during power dips.
  • Compact TSSOP-20: Reduces board space and cost.
  • 16MHz STM8A core: Sufficient performance for control loops.
