The STM8S105x4/6 access line 8-bit microcontrollers have a 16 to 32 Kbyte Flash program memory and an internal actual data EEPROM. The STM8S microcontroller family reference documentation refers to devices from this series as medium-density (RM0016).
The STM8S105x4/6 access range of devices offers the following advantages: lower system costs, performance and resilience, quick development times, and long product lifespans. An integrated actual data EEPROM with up to 300 k write/erase cycles and a high level of system integration with watchdog, internal clock oscillators, and brown-out reset decrease the system cost.
The 16 MHz CPU clock frequency, along with improved features like reliable I/O, independent watchdogs (with a separate clock source), and a clock security mechanism, ensure that the device performs as intended.
Because of the compatibility of the pinout, memory map, and modular peripherals across the typical family of product architecture, short development cycles are ensured. Because the STM8S family’s sophisticated core is created using cutting-edge technology for applications requiring an operating supply range of 2.95 V to 5.5 V, product longevity is guaranteed.

Frequently Asked Questions
What is an 8-bit microcontroller?
Microcontrollers with 8-bit data words are referred to as 8-bit microcontrollers. A microprocessor’s word length or word size refers to how many bits it can process simultaneously.
Why is the microcontroller 8bit?
The programming approach for 8-bit microcontrollers is straightforward, and its design is less complex. Typically, it just requires one supply. Contrary to some marketing claims, current 8-bit architectures consume less power than 32-bit ones since they flip fewer bus signals.
What does the eight mean in 8-bit?
This refers to a computer’s “word size,” which is the size of the data unit it can handle. A 1-bit has two potential states (1 and 0), giving it two locations to store data.
What is the difference between 8bit and 16bit microcontrollers?
Each of these microcontrollers is unique in terms of arithmetic operations. Every kind of microcontroller has a fantastic set of data. Only 0 to 255 bits can be handled by an 8-bit microprocessor, 0 to 65,535 by a 16-bit microcontroller, and 0 to 4,29,49,67,295 by a 32-bit microcontroller.
What are some 8-bit microcontroller applications?
What uses 8-bit microcontrollers can be put to is what counts most. In general, an 8-bit microcontroller can be used if a device doesn’t need to connect to the internet or has weak security requirements.
While 8-bit numbers are constrained in size, huge numbers can be divided into numerous steps, and C compilers support this (of course, this can still be done in an assembler). As a result, an 8-bit microcontroller can still be used for any application that needs to use numbers bigger than 255.
While 8-bit microcontrollers typically lack internet connectivity, they can nevertheless be quickly attached to external peripherals like ethernet controllers and Wi-Fi bridges to establish a connection. Modern security procedures demand that the peripheral(s) providing internet access use strong security safeguards and that any connection between the 8-bit microcontroller and the internet service utilizes strong encryption.
Due to the large memory requirements of encryption techniques, this could be challenging for 8-bit microcontrollers; therefore, it would be best to use a peripheral that can handle this.
