STM8S105C6T6 개요
An 8-bit microcontroller (MCU) is a single-chip computer with an 8-bit data bus, integrating a processor core, memory, and programmable input/output peripherals. The STM8S105C6T6 belongs to the STM8S family, which is part of the broader STM8 microcontroller series, positioned below the 32-bit STM32 family in STMicroelectronics' product hierarchy. It is designed for applications requiring moderate processing power, low power consumption, and rich peripheral integration, such as industrial control, home appliances, and automotive body electronics.
Key features include a 10-bit analog-to-digital converter (ADC) with up to 10 channels, multiple 16-bit timers, and a full set of communication interfaces: UART, SPI, and I2C. The device also integrates a true data EEPROM with up to 300,000 write/erase cycles, enabling data storage without external memory. The STM8 core operates at up to 16 MHz, delivering 16 MIPS throughput, and supports a wide range of clock sources including internal RC oscillators and external crystals.
The STM8S105C6T6 is built on a high-density Flash technology, providing robust program memory endurance and fast programming. The architecture includes a nested interrupt controller with 28 interrupt vectors, enhancing real-time responsiveness. The device also features a low-power mode with typical current consumption of 5 µA in Halt mode, making it suitable for battery-powered applications.
Typical applications include industrial automation, home appliances (e.g., washing machines, air conditioners), power tools, and automotive body control modules. The rich peripheral set and 5V-tolerant I/Os allow direct interfacing with sensors, relays, and displays without level shifting. The LQFP-48 package provides 38 I/O pins, offering ample connectivity for control and communication.
When designing with this MCU, ensure proper decoupling of the VDD and VDDA pins with 100 nF capacitors placed close to the device. The NRST pin should be connected to a 100 nF capacitor to ground for reliable reset. For applications requiring precise timing, use an external crystal oscillator with load capacitors as specified in the datasheet.

설계 노트
Decouple the VDD and VDDA pins with 100 nF ceramic capacitors placed as close to the pins as possible. Additionally, use a 4.7 µF bulk capacitor on the main supply rail. The VDDA pin should be connected to VDD through a ferrite bead or a low-pass filter to reduce noise on the analog supply, which is critical for ADC accuracy.
For the LQFP-48 package, ensure proper solder paste stencil design to avoid bridging between pins. The exposed pad (if present) should be connected to ground with multiple vias for thermal relief. Keep high-speed communication lines (SPI, I2C) short and away from high-current traces to minimize crosstalk.
The NRST pin must be connected to a 100 nF capacitor to ground to ensure reliable reset. Do not leave the NRST pin floating. Also, ensure that the supply voltage does not exceed 5.5V, as this can damage the device. For programming, use the SWIM interface with a 1 kΩ resistor in series to the SWIM pin.
