The STMicroelectronics STM8AL3146UCY is an 8-bit STM8A MCU in a 32-VFQFN package. It runs at 16MHz with 16KB flash and 2KB RAM. Operating from 1.65V to 3.6V, it integrates DMA, brown-out detection, POR, PWM, and WDT. Rated for -40°C to 125°C, it is designed for automotive and industrial applications.
- Ultra-low voltage (1.65V) – ideal for single-cell battery operation.
- High temperature tolerance (125°C) – suitable for harsh environments.
- DMA controller – reduces CPU overhead for data streaming.
- Compact 32-VFQFN – saves space in portable designs.
Automotive Body Control Modules
The 125°C rating and 1.65V operation make it ideal for under-hood sensors and actuators.
Battery-Powered Key Fobs
Ultra-low voltage operation extends battery life, while 16KB flash stores rolling code algorithms.
Industrial Temperature Transmitters
DMA offloads ADC data transfer, and the wide temperature range suits process control.
Portable Gas Detectors
Low power consumption and WDT ensure reliable operation in safety-critical devices.
Medical Implantable Devices
The 1.65V minimum and small 32-VFQFN package enable compact, low-power designs.
LED Lighting Controllers
PWM outputs drive LED drivers, and brown-out detection prevents flicker during power dips.
