The STM8S105K6T3CTR is an 8-bit MCU from STMicroelectronics' STM8S family, built around the STM8 core running at 16 MHz. The wide supply range from 2.95 V to 5.5 V means it can sit on a legacy 5 V industrial bus or a modern 3.3 V rail without a level translator on the power input.
The 7-channel 10-bit ADC handles analog inputs like thermistors or potentiometers without an external converter.
It remains a current-production device suitable for new designs.
Within the STM8S105 value line, pin-compatible density options exist with different Flash and RAM sizes — for example, the STM8S105K4 (16 KB Flash) or STM8S105K6 (32 KB Flash) share the same 32-LQFP footprint. Verify the exact memory and peripheral match against your firmware image size before substituting.
