STM8S105K6B6 Descripción general
A microcontroller is a programmable semiconductor that integrates a processor core, memory, input/output ports, timers, and communication peripherals on one device. The STM8S105K6B6 belongs to the STM8S access-line family: an 8-bit MCU platform intended for compact control systems where deterministic peripheral access, low component count, and simple embedded software development are important. Its 32 KB Flash provides room for application firmware, while integrated data EEPROM supports parameter storage and calibration data.
The verified specifications identify a 16 MHz operating frequency, 32 KB Flash organized as 32K × 8, 2K × 8 RAM, 25 I/O pins, and a 10-bit ADC. The verified sources also identify UART, SPI, I2C, timers, and mixed-signal acquisition capabilities. These peripherals allow the MCU to connect sensors, communicate with external controllers, generate timing signals, and perform basic analog measurements without requiring several discrete support devices.
The STM8S105K6B6 is packaged in a 32-SDIP through-hole format with a stated 0.400-inch, 10.16 mm package dimension. Through-hole construction can simplify prototype assembly, inspection, and manual rework compared with fine-pitch surface-mount packages. The device is suitable for applications such as compact motor controllers, industrial sensing modules, communication interfaces, and embedded automation products, provided the firmware and board design are verified against the manufacturer datasheet.
Designers should verify supply voltage, clock configuration, peripheral pin multiplexing, ADC accuracy, reset behavior, and programming requirements against the manufacturer datasheet before release. The 8-bit architecture and 32 KB Flash footprint are appropriate for focused control tasks, but software memory planning is essential when combining multiple communication protocols and control functions. Verify exact electrical limits and package details before using the device as a drop-in replacement for another MCU.
This page consolidates verified distributor specifications, official manufacturer information, pricing context, sourcing links, and engineering guidance. It does not infer unprovided electrical limits, pin names, lifecycle claims, or alternative-device compatibility.

Aplicaciones típicas
STM8S105K6B6 es adecuado para 6 aplicacións: Compact Motor-Control Module, Industrial Sensor Interface, Communication Interface Board, Automatic Door and Access Control, Small Appliance Controller, Prototype and Educational Control Board.
Compact Motor-Control Module
The STM8S105K6B6 fits compact motor-control and motion-control modules because it combines an 8-bit STM8 core, 16 MHz operation, 25 I/O pins, timers, and a 10-bit ADC in one 32-SDIP device. The MCU can coordinate actuator commands, read analog feedback, and interface with a host or sensor network through UART, SPI, or I2C. Its 32 KB Flash provides space for application firmware, while integrated EEPROM can retain calibration or configuration data. Before selecting it for a motor circuit, verify PWM behavior, timer limits, ADC timing, supply range, and thermal conditions in the manufacturer datasheet; the supplied data does not confirm motor-drive output ratings.
Recomendado
Industrial Sensor Interface
For industrial sensing equipment, the STM8S105K6B6 provides a practical combination of mixed-signal acquisition, 25 I/O pins, 10-bit ADC capability, and serial communications. It can read sensor outputs, perform local thresholding or control, and forward data over UART or I2C while SPI supports additional peripheral connections. The 32 KB Flash and 2K × 8 RAM fit focused acquisition and control firmware, and integrated EEPROM is useful for storing configuration values. Verify the ADC input range, sampling behavior, pin multiplexing, and communication timing against the official STM8S105K6 documentation before using the device in safety- or precision-critical instrumentation.
Recomendado
Communication Interface Board
STM8S105K6B6 is appropriate for a compact protocol-conversion or communication interface board when the design needs UART, SPI, and I2C in an 8-bit embedded controller. The MCU can bridge a local sensor or actuator bus, format messages, and provide host-control commands through one of the supported serial interfaces. Its 16 MHz operating point and 32 KB Flash provide room for protocol handlers and application logic, while the 32-SDIP package is convenient for through-hole prototypes and serviceable assemblies. Confirm peripheral pin assignments, maximum interface rates, electrical levels, and any required level-shifting components in the manufacturer datasheet and application notes.
Recomendado
Automatic Door and Access Control
The STM8S105K6B6 can support a compact access-control peripheral that reads switches or sensors, drives indicator and lock-control signals, and communicates with a controller over UART or I2C. Its 25 I/O pins provide more control and monitoring options than a minimal microcontroller, while the 10-bit ADC supports analog sensing where appropriate. The 32 KB Flash is suitable for state-machine and configuration firmware, and integrated EEPROM can retain device settings. A production design must confirm output drive limits, external transistor or driver selection, reset behavior, supply tolerances, and any environmental requirements; those parameters are not present in the supplied verified snippets.
Recomendado
Small Appliance Controller
A small appliance controller can use the STM8S105K6B6 to manage buttons, displays, relays, temperature-related sensors, and service communications. The MCU's timer resources support periodic control tasks, UART supports diagnostics, and I2C or SPI can connect to sensors and external devices. Its 8-bit architecture and 32 KB Flash are appropriate for deterministic embedded control rather than high-compute workloads. Integrated EEPROM helps preserve configuration and calibration information between power cycles. Designers should verify relay-driver sizing, isolation, ADC input protection, EMI behavior, and thermal margins using application-specific calculations; only the core MCU and package information are verified here.
Recomendado
Prototype and Educational Control Board
The STM8S105K6B6 is well suited to through-hole prototypes because the verified package is 32-SDIP, with a stated 0.400-inch and 10.16 mm dimension. Students and engineers can use the MCU to learn embedded firmware, GPIO control, timers, ADC acquisition, UART communication, SPI, and I2C without resorting to a complex fine-pitch footprint. The 32 KB Flash and integrated EEPROM provide sufficient resources for small demonstrations, while 25 I/O pins expose useful control and communication signals. Before wiring a board, verify the complete pinout, programming connector, clock requirements, supply voltage, reset circuit, and decoupling recommendations from official STMicroelectronics documentation.

Notas de diseño
Use the 32-SDIP footprint and verify every hole location against the official package drawing before layout release. The supplied data identifies the package as 32-SDIP with a stated 0.400-inch and 10.16 mm dimension, but it does not provide a complete pinout. Reserve the programming interface, power pins, ground connections, decoupling positions, and any external oscillator or reset components only after checking the manufacturer datasheet.
Do not infer the operating-voltage range from the distributor's 3.3 V/5 V description. Confirm the device's supply limits, I/O voltage domains, ADC input range, and current consumption from the official datasheet. Apply the manufacturer's recommended decoupling and power-sequence requirements, and check regulator headroom for all 5 V or 3.3 V peripherals used with the MCU.
Map UART, SPI, and I2C pins against the verified package pinout and account for alternate-function conflicts. Keep communication traces short where practical, provide continuous ground references, and use appropriate pull-ups or level translation where the external bus requires them. Timing, rise time, capacitance, and maximum bus rates are not included in the supplied data, so validate them from the manufacturer specifications and board-level measurements.
The part is an 8-bit MCU with 32 KB Flash and 2K × 8 RAM, so firmware size and RAM allocation should be checked early. Do not confuse the integrated EEPROM with general-purpose backup storage without checking its endurance and write-cycle limits. Also avoid treating STM8S105K6U6A or STM8S005K6T6C as direct replacements until their package, pinout, electrical limits, and peripheral behavior are independently verified.
Información de cumplimiento
The supplied verified data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Compliance must be confirmed from current STMicroelectronics documentation before use in regulated products.
