The STM8S105x4/6 access line 8-bit microcontrollers offer a flash program memory of between 16 and 32 Kbytes, plus integrated true data EEPROM. All STM8S105x4/6 access line devices offer reduced system costs, outstanding power and robustness, short development cycles and a long service life. The integrated true data EEPROM reduces system costs and provides 300-k write/erase cycles as well as high-level system integration with internal clock oscillators, watchdog and brown-out reset. Device performance is ensured by a 16-MHz CPU clock frequency and improved features such as robust I/Os, independent watchdogs (with separate clock source) and a clock security system. Short development cycles are guaranteed by application scalability across a common product architecture with compatible pinout, memory map and modular peripherals. An advanced core, which is manufactured using state-of-the-art technology for applications with an operating voltage of 2.95 V to 5.5 V, ensures a long service life for all products in the STM8S range. Full documentation plus a wide range of development tools are available. https://elecena.pl/product/18959349/stm8s105c4t6-stm8s-8-bit-microcontroller-16-mhz-32-kb-2-kb-lqfp-48 2021-06-29 https://elecena.pl/product/18959349/stm8s105c4t6-stm8s-8-bit-microcontroller-16-mhz-32-kb-2-kb-lqfp-48 2022-09-29 https://elecena.pl/product/18959349/stm8s105c4t6-stm8s-8-bit-microcontroller-16-mhz-32-kb-2-kb-lqfp-48 2022-10-22 https://elecena.pl/product/18959349/stm8s105c4t6-stm8s-8-bit-microcontroller-16-mhz-32-kb-2-kb-lqfp-48 2023-01-06 https://elecena.pl/product/18959349/stm8s105c4t6-stm8s-8-bit-microcontroller-16-mhz-32-kb-2-kb-lqfp-48 2023-04-07 https://elecena.pl/product/18959349/stm8s105c4t6-stm8s-8-bit-microcontroller-16-mhz-32-kb-2-kb-lqfp-48 2023-08-24 https://elecena.pl/product/18959349/stm8s105c4t6-stm8s-8-bit-microcontroller-16-mhz-32-kb-2-kb-lqfp-48 2024-04-25 https://elecena.pl/product/18959349/stm8s105c4t6-stm8s-8-bit-microcontroller-16-mhz-32-kb-2-kb-lqfp-48 2024-05-19 https://elecena.pl/product/18959349/stm8s105c4t6-stm8s-8-bit-microcontroller-16-mhz-32-kb-2-kb-lqfp-48 2024-06-08 https://elecena.pl/product/18959349/stm8s105c4t6-stm8s-8-bit-microcontroller-16-mhz-32-kb-2-kb-lqfp-48 2024-07-14 https://elecena.pl/product/18959349/stm8s105c4t6-stm8s-8-bit-microcontroller-16-mhz-32-kb-2-kb-lqfp-48 2025-12-26 https://elecena.pl/product/18959349/stm8s105c4t6-stm8s-8-bit-microcontroller-16-mhz-32-kb-2-kb-lqfp-48 2026-01-30
