The STM8AL3146UAX is a low-power 8-bit microcontroller from STMicroelectronics. It features an STM8 core running at 16MHz with 16KB flash and 2KB RAM. The 32-VFQFN package is suited for compact designs. It operates from 1.65V to 3.6V and -40°C to 85°C. Integrated DMA, PWM, brown-out reset, and watchdog timer make it ideal for battery-powered applications.
- Ultra-low 1.65V operation extends battery life in single-cell devices.
- DMA reduces CPU load for peripheral data transfers, saving power.
- 16MHz performance is sufficient for real-time control without over-provisioning.
- Small VFQFN-32 package saves PCB space in wearables.
Low-Power Battery Monitors
1.65V minimum supply allows operation from a single alkaline cell down to end-of-life.
Portable Consumer Electronics
16MHz STM8 core with DMA handles user interface and sensor fusion in handheld devices.
Smart Metering Systems
Low power consumption and WDT ensure long-term reliable operation in utility meters.
Medical Diagnostic Pens
Compact VFQFN package and low voltage enable miniaturized glucose or ketone meters.
Wireless Sensor Nodes
PWM and brown-out reset support duty-cycled RF transceivers for environmental monitoring.
Access Control Keypads
Robust I/O and 16KB flash store encryption keys and user profiles securely.
