What the STM8S105K4T3CTR brings to an 8-bit control design
The STM8S105K4T3CTR is an 8-bit microcontroller from STMicroelectronics' STM8S series, built around the STM8 core clocked at 16 MHz.
The 16 MHz clock rate is the performance ceiling for this 8-bit STM8 core. For typical control loops (PID, sensor polling, PWM updates) running from Flash with zero wait states, instruction throughput is deterministic at roughly one cycle per instruction for simple operations.
Memory map and peripheral set
With 16 KB of Flash, 2 KB of RAM, and 1 KB of EEPROM, this part handles moderate firmware images and keeps calibration constants or configuration data in the EEPROM without an external serial memory. The 1 KB EEPROM endurance matters for field-update counters or wear-leveled parameter storage.
For current-production parts like this, we source through authorized distribution channels and can quote against an RFQ with confirmed availability and pricing.
