The STMicroelectronics STM8AF5288TCX is an 8-bit automotive MCU based on the STM8A core. It operates at 24MHz with 64KB flash and 6KB RAM. Its 3V to 5.5V supply range and 48-LQFP package make it versatile for automotive body and industrial control. Integrated Brown-out Reset, POR, PWM, and WDT enhance system reliability.

  • Wide voltage range (3V-5.5V): Compatible with 3.3V and 5V logic.
  • Automotive-grade temperature: -40°C to 125°C for harsh environments.
  • 64KB flash: Ample space for complex firmware.
  • Integrated safety peripherals: Reduces external supervision components.

Automotive Lighting Control

5.5V operation and PWM channels drive LED arrays with high-side switches.

Industrial Sensor Nodes

24MHz core with WDT ensures reliable operation in remote monitoring stations.

Power Window Modules
