The STM8S105x4/6 access line 8-bit microcontroller provides 16 to 32 KB flash program memory and integrated true data EEPROM. The STM8S microcontroller series reference manual (RM0016) refers to the devices in this series as medium density devices. All devices in the STM8S105x4/6 access series have the following advantages: reducing system costs, performance and robustness, shortening development cycles, and product lifespan. Thanks to the integration of real data EEPROM with up to 300 k write/erase cycles, as well as high system integration with internal clock oscillator, watchdog, and undervoltage reset, system costs have been reduced. The STM8S105C6T6 16 MHz CPU clock frequency and enhanced features (including powerful I/O, independent watchdog (with separate clock source), and clock security system) ensure device performance. Due to the application scalability of the universal series product architecture with compatible pin arrangement, memory mapping, and modular peripherals, it ensures a shorter development cycle. The STM8S series is manufactured using the most advanced technology and is suitable for applications with working power supplies ranging from 2.95 V to 5.5 V, ensuring the product's lifespan.
