The STM8AF6266UDY from STMicroelectronics is a robust 8-bit MCU built on the STM8A core. It offers 32KB flash and 2KB RAM, running at 16MHz. With a wide 3V to 5.5V supply range and -40°C to 150°C operation, it is designed for extreme automotive and industrial use. The 32-VFQFN package saves board space while providing excellent thermal performance.
- High-temperature tolerance: 150°C rating enables placement near engines or exhaust systems.
- Wide voltage range: 3-5.5V simplifies direct battery connection without extra regulators.
- Integrated safety features: POR, brown-out reset, and WDT reduce external supervision ICs.
- Compact 32-VFQFN: Low footprint for space-constrained ECU designs.
Automotive Body Control Modules
With a 150°C junction temperature rating and 5.5V supply tolerance, it handles harsh under-hood environments.
Industrial Sensor Interfaces
The 16MHz STM8A core and 2KB RAM enable real-time sensor data processing with low latency.
Power Management Units
Integrated PWM and brown-out detection ensure stable voltage regulation in battery-backed systems.
