The STM8S103K3U6TR from STMicroelectronics is an 8-bit microcontroller built on the STM8 core. It operates at up to 16MHz with 8KB of flash memory and 1KB of RAM. The device supports a supply voltage from 2.95V to 5.5V and includes integrated features such as brown-out detection, power-on reset, PWM, and a watchdog timer. Housed in a compact 32-UFQFN package, it is designed for cost-sensitive embedded control applications.
- Wide voltage range (2.95V-5.5V): Simplifies power supply design and supports both 3.3V and 5V logic.
- Integrated WDT and BOR: Enhances system reliability by preventing code runaway and managing power failures.
- Compact 32-UFQFN package: Saves PCB space for space-constrained designs.
- 16MHz STM8 core: Provides sufficient processing power for real-time control loops.
Industrial Control
Use the STM8S103K3U6TR in relay and motor control units. Its 16MHz core and PWM timers provide precise timing for switching applications.
Sensor Interfacing
Interface with analog sensors using the built-in ADC. The 2.95V-5.5V supply range simplifies direct connection to both digital and analog sensor rails.
