The STM8S105K6U3ATR from STMicroelectronics is an 8-bit MCU built on the high-performance STM8 core. It delivers 16 MHz operation with 32 KB flash and 2 KB RAM. The device supports a wide 2.95V to 5.5V supply, making it flexible for industrial and consumer designs. Integrated features include brown-out detection, POR, PWM, and a watchdog timer. Housed in a compact 32-UFQFN package, it operates reliably from -40°C to 125°C.
- Wide voltage range (2.95V-5.5V) simplifies power supply design and supports legacy 5V logic.
- High temperature tolerance (-40°C to 125°C) enables use in automotive and industrial environments.
- Integrated WDT and brown-out reset improve system reliability without external components.
- Compact UFQFN package saves board space for space-constrained applications.
