The STM8AL3L46TAY is an 8-bit microcontroller from STMicroelectronics, based on the STM8 core. It runs at up to 16MHz and provides 16KB of flash memory with 2KB of RAM. The supply voltage ranges from 1.65V to 3.6V, and it includes features like brown-out detection, DMA, PWM, and WDT. Packaged in a 32-LQFP, it operates from -40°C to 85°C, making it suitable for automotive and industrial control applications.
- Double the flash (16KB) compared to similar STM8AL parts, allowing more complex firmware.
- Low 1.65V operation supports single-cell alkaline or lithium batteries.
- Integrated DMA improves data throughput without CPU intervention.
- Wide operating temperature range (-40°C to 85°C) covers most industrial environments.
Automotive Window Lift Controllers
The 16KB flash stores position calibration data, while the 16MHz STM8 core provides fast response to switch inputs, operating reliably at 1.65V-3.6V.
Battery-Powered Thermostats
Low power consumption and WDT ensure long battery life in smart thermostats, with PWM driving LCD backlights.
Industrial Valve Positioners
The DMA controller handles sensor data acquisition, while the 2KB RAM buffers control loops for precise valve positioning.
Portable Gas Detectors
Its compact LQFP-32 package and low voltage operation make it suitable for handheld safety devices that must operate for years on a single cell.
Smart Lighting Ballasts
PWM outputs control dimming levels, and the brown-out reset prevents flicker during voltage sags.
Medical Infusion Pumps
The 16KB flash stores dosing protocols, and the -40°C to 85°C range ensures safe operation in clinical environments.
