The STM8S903K3T6C from STMicroelectronics is a cost-effective 8-bit MCU with 8KB flash and 1KB RAM. Running at 16MHz, it delivers efficient performance for control applications. The 32-LQFP package offers a compact footprint with sufficient I/O. With a supply range of 2.95V to 5.5V, it integrates well into existing power architectures. Built-in brown-out reset and watchdog timer enhance system robustness.
- Cost-optimized 8-bit core: Reduces BOM cost for high-volume products.
- Wide supply range (2.95V-5.5V): Directly interfaces with 5V peripherals.
- Compact 32-LQFP: Saves PCB space while providing 32 pins.
- Reliable operation: BOR, POR, and WDT protect against power anomalies.
Motor Control for Small Appliances
16MHz core with PWM and WDT handles sensorless BLDC control; 8KB flash fits commutation routines.
Battery Management System
