STM8S207K6T6 - 24MHz 8-bit MCU, 32KB Flash | STMicroelectronics
MPN: STM8S207K6T6 ✓ Hoạt độngSTM8S207K6T6 Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer with an 8-bit data bus, executing instructions on 8-bit words. It integrates a CPU, memory (Flash, RAM, EEPROM), and peripherals (timers, ADC, communication interfaces) on one die. In the system hierarchy, an 8-bit MCU sits below 16-bit and 32-bit MCUs in processing power but offers lower cost, simpler architecture, and lower power consumption, making it ideal for control-oriented tasks like motor control, sensor interfacing, and human-machine interfaces. The STM8S207K6T6 belongs to the STM8S20xxx performance line, which balances performance and peripheral richness for mid-range embedded applications.
Key features include a 24 MHz CPU clock, 32 Kbytes of Flash, 2 Kbytes of RAM, 2 Kbytes of EEPROM, a 10-bit ADC with up to 10 channels, two 16-bit timers, one 8-bit timer, two UARTs, SPI, I²C, and a CAN 2.0B controller. The device operates from 2.95V to 5.5V, making it suitable for 3.3V and 5V systems. It also features a low-power mode with typical current consumption of 5.4 mA at 24 MHz, and a halt mode with 1.5 µA typical current.
The STM8S207K6T6 uses a Harvard architecture with a 3-stage pipeline, achieving up to 20 MIPS at 24 MHz. It includes an embedded debug module (SWIM) for in-circuit debugging and programming, and a single-wire interface for firmware updates. The CAN controller supports CAN 2.0B active mode, enabling robust industrial networking. The device is manufactured using ST's proprietary 130nm process, balancing performance and power efficiency.
Typical applications include industrial control systems, home appliances, automotive body electronics (non-safety), sensor nodes, and communication gateways. The CAN interface makes it particularly suitable for automotive and industrial CAN bus networks, while the multiple UARTs and SPI/I²C support diverse peripheral connectivity.
When designing with this MCU, ensure proper decoupling of the VDD and VDDA pins with 100nF capacitors placed close to the pins. The SWIM pin should be pulled up with a 10kΩ resistor for reliable programming. For CAN applications, an external CAN transceiver (e.g., TJA1050) is required, and the bus termination resistor should be 120Ω at each end of the CAN bus.

Ghi chú thiết kế
Decouple the VDD and VDDA pins with 100nF ceramic capacitors placed as close to the pins as possible. Additionally, place a 10µF electrolytic capacitor near the VDD pin for bulk decoupling. The VDDA pin should be connected to VDD through a ferrite bead to filter high-frequency noise, improving ADC accuracy. Ensure the VSSA pin is connected to a clean analog ground, separate from the digital ground, to minimize noise coupling into the ADC.
For the SWIM pin (PC0), add a 10kΩ pull-up resistor to VDD to ensure reliable in-circuit programming and debugging. The NRST pin (PC1) should have a 100nF capacitor to ground for reset noise filtering. When using an external crystal on OSC_IN/OSC_OUT (PC2/PC3), place the crystal and load capacitors (typically 20pF) close to the pins, with a ground plane underneath to reduce parasitic capacitance. For CAN applications, place the CAN transceiver (e.g., TJA1050) close to the MCU and route the CAN_TX/CAN_RX traces as a differential pair with 120Ω termination at both ends of the bus.
Do not exceed the absolute maximum ratings: VDD must not exceed 6.5V, and I/O pins must not be driven above VDD + 0.3V. Ensure the ADC input voltage does not exceed VDDA, as this can damage the ADC. When using the CAN interface, remember that the MCU's CAN controller requires an external transceiver; connecting CAN_TX/CAN_RX directly to the bus will not work. Also, the SWIM pin is open-drain and must be pulled up for programming; leaving it floating may cause programming failures. Finally, verify the firmware fits within the 32 Kbytes of Flash, as the STM8S207K6T6 has no external memory interface.
