STM8S207K8T6C - 24MHz 64KB 8-Bit MCU | STMicroelectronics
部品番号: STM8S207K8T6C ✓ 生産中STM8S207K8T6C 概要
An STM8S performance-line microcontroller belongs to the 8-bit MCU hierarchy and provides economical control for industrial equipment, communications modules, motor-control subsystems, and consumer products. Unlike application-specific controllers, the STM8S207K8T6C integrates programmable digital interfaces and analog conversion in one device, allowing a compact design to handle sensing, communications, timing, and actuator control without requiring a separate host processor.
The 24 MHz clock supports faster instruction execution than many entry-level 8-bit MCUs, while the 64 KB Flash configuration provides room for a larger application program than the smallest STM8 devices. Integrated EEPROM supports nonvolatile parameter storage, and the 10-bit ADC enables direct analog measurement. Two UARTs, SPI, I2C, and CAN provide options for sensor access, external peripherals, data logging, and network-connected equipment.
The STM8S207K8T6C belongs to the STM8S20xxx performance line, which supports devices from 32 to 128 KB of Flash. Its 32-pin LQFP package exposes the MCU's GPIO, communication, timer, debug, reset, clock, and power functions on a conventional leaded surface-mount footprint. This package is easier to inspect and solder than very fine-pitch packages, making it suitable for prototypes, serviceable equipment, and moderate-production assemblies.
Typical applications include industrial sensor controllers, CAN-connected equipment, UART-based data concentrators, SPI peripheral controllers, motor and valve-control modules, and compact consumer appliances. The combination of CAN and multiple serial interfaces is especially useful when a board must monitor sensors while communicating with a higher-level controller or service network.
PCB design should preserve clean supply decoupling near the power pins, route sensitive analog and clock signals away from high-current switching nodes, and follow the manufacturer datasheet for alternate-function assignment and unused-pin treatment. Firmware replacement must also account for the exact Flash density, bootloader assumptions, peripheral configuration, and pin multiplexing of the selected device.
This product page consolidates the key MCU capabilities, verified source links, comparison parameters, application guidance, and design considerations needed to plan an STM8S207K8T6C-based board efficiently.

CAN-Connected Industrial Sensor Controller
The STM8S207K8T6C fits a compact industrial sensing node that must convert analog inputs and report results over a CAN network. Its 10-bit ADC supports direct measurement of sensor signals, while the 24 MHz core provides useful control-processing headroom. The integrated CAN interface avoids a separate network transceiver at the digital logic level, and the second UART can support local service communications or a human-readable diagnostic port. With 64 KB Flash, the firmware can accommodate calibration data, device-specific conversion logic, protocol handling, and field-update routines. The 32-pin LQFP package also leaves access to GPIO and timer resources for digital inputs, status indicators, and actuator outputs.
UART Data Concentrator
The STM8S207K8T6C is well suited to a data concentrator that collects information from several peripherals and forwards it through a serial link. Two UART interfaces allow simultaneous connection to upstream and downstream equipment, while SPI and I2C provide dedicated paths for sensors, memory, or peripheral devices. The 24 MHz STM8S core can handle protocol conversion and data buffering, and the 64 KB Flash capacity provides room for protocol stacks and application logic. Its integrated EEPROM is useful for configuration and counters that must survive power cycling. The 32-pin LQFP package supports a straightforward mixed-signal layout with accessible debug and programming connections.
SPI Peripheral Controller
The STM8S207K8T6C can act as the host controller in an SPI-based measurement or storage subsystem. Its dedicated SPI interface supports rapid communication with sensors, display controllers, flash memory, and other serial peripherals, while I2C and two UARTs allow additional devices to coexist without sharing one bus. The 10-bit ADC can sample local analog conditions alongside digital sensor results. At 24 MHz, the MCU provides more processing performance than basic 8-bit controllers intended only for simple I/O. Its 64 KB Flash is suitable for drivers, acquisition routines, calibration logic, and communication handling within a single compact controller.
Motor and Valve Control Module
The STM8S207K8T6C is appropriate for a small motor, valve, or actuator-control module that needs deterministic timing and several communication options. Integrated timers support periodic control and input-capture tasks, while the GPIO pins can interface with sensors, switches, and driver-control signals. The 24 MHz core allows the firmware to coordinate timing, status monitoring, and safety checks, and the 10-bit ADC can monitor analog feedback. SPI or I2C can connect to a dedicated driver or sensor, and CAN or UART provides supervisory communication. The 64 KB Flash supports more elaborate control algorithms and diagnostics than the smallest STM8 density options.
Embedded Data Logger
The STM8S207K8T6C supports a compact embedded data logger that periodically records measurements and sends them to a host system. The 10-bit ADC can acquire process or environmental signals, the integrated EEPROM can retain configuration information, and the 24 MHz core can perform sampling control, scaling, filtering, and event handling. UART provides a simple diagnostic or upload path, while SPI or I2C can connect to external storage or sensors. The 64 KB Flash configuration leaves space for buffering routines and communication protocols. Its 32-pin LQFP package is particularly convenient for boards assembled with conventional surface-mount production equipment and for designs requiring easy visual inspection.
Consumer Control Panel
The STM8S207K8T6C can manage a consumer control panel containing buttons, indicators, a display interface, and several serial peripherals. Its GPIO and timer resources support key scanning, debouncing, blinking, and periodic tasks, while I2C or SPI can connect to a display or sensor. The 10-bit ADC supports analog controls or monitoring, and UART or CAN provides a path to a main appliance controller. The 24 MHz core can coordinate multiple interface tasks, and the 64 KB Flash permits richer user-interface behavior and diagnostics. The 32-pin LQFP package combines a practical pin count with a package that remains straightforward to assemble and service.

設計ノート
Place the capacitors specified by the manufacturer close to the corresponding supply pins and use the shortest practical return path to the ground plane. Keep the 10-bit ADC input traces away from switching nodes and high-current driver paths, and provide a quiet ground reference for analog measurements. Route the clock and programming interface away from noisy peripheral buses to reduce coupling into timing-sensitive and debug operations.
Use the manufacturer pin-description table to assign every 32-pin LQFP connection and to identify alternate-function multiplexing before finalizing the schematic. Unused pins should be treated according to the datasheet rather than left without a deliberate electrical decision. Reserve access to the programming and debug signals in the layout so firmware can be updated without redesigning the enclosure or forcing board rework.
Do not assume that a same-package family member is firmware-compatible without checking its Flash density, EEPROM capacity, peripheral set, boot configuration, and ordering suffix. The STM8S207K6T6C has a different density code from the STM8S207K8T6C, so an existing image, bootloader, or address map may require modification. Validate the exact ordering information and pin descriptions against the manufacturer datasheet before releasing a substitution.
Locate any CAN transceiver or other high-speed interface circuitry away from the MCU's analog and clock areas, and follow the interface device's grounding and termination recommendations. Stagger clocks and communication lines when practical, avoid routing them parallel to long power-return paths, and keep external connectors and transient-producing devices at the board perimeter. These measures reduce the chance that communication activity degrades ADC readings or destabilizes control firmware.
