STM8S207S6T3C - 24MHz 8-Bit MCU, 32KB Flash | STMicroelectronics
Артикул: STM8S207S6T3C ✓ АктивенSTM8S207S6T3C Обзор
STM8S207S6T3C belongs to the STM8S20xxx family of 8-bit microcontrollers. An 8-bit MCU integrates a CPU, program memory, data memory, peripherals, and general-purpose I/O into one device, allowing compact embedded products to control sensors, actuators, communications, and user interfaces without requiring a separate processor.
The device provides a 24 MHz clock, 10-bit ADC channels, timers, two UARTs, SPI, I2C, and CAN connectivity. These interfaces support industrial monitoring, motor and actuator control, communications modules, measurement equipment, and compact consumer or appliance controllers. The 32 KB Flash capacity is suitable for moderate firmware sizes where code density and deterministic embedded control are more important than the resources of a 32-bit MCU.
The STM8S207S6T3C is identified as an active performance-line device. Its 3.0 V to 5.5 V operating supply and -40 °C to 125 °C temperature range support industrial temperature requirements. The LQFP package provides 38 externally available I/O pins, enabling simultaneous peripheral connections and easier prototype assembly than a very small leadless package.
For new designs, place the device on a multilayer PCB with short, separated analog and digital return paths, use a separate 100 nF bypass capacitor at each supply pin, and follow the recommended external clock and reset network from the manufacturer reference manual. Confirm all peripheral pin assignments and alternate-function settings in the STM8S207x pin description table before finalizing the schematic and PCB layout.
This product page summarizes the manufacturer specifications, identifies package and interface considerations, and provides a practical comparison framework for engineers evaluating STM8S207-family alternatives. It is intended to support design selection, sourcing, and hardware bring-up rather than replace the complete reference manual.

Типичное применение
STM8S207S6T3C подходит для 6 применениеs: CAN-Based Industrial Sensor Node, Motor and Actuator Controller, UART-Based Communications Module, ADC-Based Measurement Instrument, Appliance and Embedded Control Board, Automotive or Harsh-Environment Auxiliary Module.
CAN-Based Industrial Sensor Node
The STM8S207S6T3C fits a compact sensor node because it combines a 24 MHz 8-bit core, 10-bit ADC, CAN, two UARTs, and 38 I/O ports in a 44-pin LQFP package. The ADC can acquire sensor signals while CAN carries data between distributed nodes, and the 3.0 V to 5.5 V supply range suits conventional industrial logic. Use a protected CAN transceiver, correct termination, and separate analog filtering where required. The 2 KB RAM is useful for short data buffers, while 32 KB Flash accommodates protocol and control firmware. Confirm the exact pin assignments and peripheral mapping in the manufacturer datasheet before laying out the board.
Рекомендуется
Motor and Actuator Controller
The STM8S207S6T3C is appropriate for small motor and actuator control systems requiring deterministic embedded timing and several communication interfaces. Its timer resources support timing-sensitive control tasks, while the 10-bit ADC can monitor motor or sensor conditions and the 38 I/O ports provide discrete control connections. The 2 KB RAM and 32 KB Flash support compact motor-control logic without a larger processor. Power transistors or gate drivers should be placed outside the MCU, with separate return paths and protection for inductive noise. The LQFP package also leaves adequate board area for power conversion and signal-conditioning components.
Рекомендуется
UART-Based Communications Module
The STM8S207S6T3C can serve as the controller in a compact communications module because it provides two UARTs alongside SPI and I2C. One UART can support a host processor or diagnostic interface while another connects to a local sensor, radio, or service port. At 24 MHz, the MCU provides useful processing headroom for framing, buffering, and status handling within its 2 KB RAM, while 32 KB Flash supports application and protocol code. The 3.0 V to 5.5 V supply range simplifies integration with common 5 V interface circuits. Select connector protection and interface levels carefully, and route communication traces away from switching power nodes.

ADC-Based Measurement Instrument
The STM8S207S6T3C suits compact measurement instruments that require analog inputs, calibration storage, and local control. Its 10-bit ADC with 9 channels allows several sensor inputs to be sampled, while the integrated 1 KB EEPROM can retain calibration or configuration information. The 32 KB Flash and 2 KB RAM are adequate for control loops, measurement processing, and a user interface when the application remains focused. The -40 °C to 125 °C specification supports demanding industrial environments. Use an RC or differential front end appropriate to the source impedance, reference the ADC carefully, and separate analog and digital ground paths to improve measurement repeatability.
Рекомендуется
Appliance and Embedded Control Board
The STM8S207S6T3C can control compact appliances and embedded products where a deterministic 8-bit MCU, mixed-signal inputs, and multiple serial interfaces are more appropriate than a higher-cost 32-bit processor. Its 24 MHz clock, 32 KB Flash, 2 KB RAM, and 1 KB EEPROM support motor or relay sequencing, button handling, sensing, and status reporting. The 38 I/O ports provide substantial connectivity for displays, sensors, and actuators, while the 44-pin LQFP package is practical for automated assembly and inspection. The 3.0 V to 5.5 V supply range fits many appliance rails. Validate fault handling and brownout behavior for safety-relevant loads.
Рекомендуется
Automotive or Harsh-Environment Auxiliary Module
The STM8S207S6T3C is a candidate for auxiliary modules requiring broad temperature tolerance, serial connectivity, and a compact 44-pin LQFP footprint. Its -40 °C to 125 °C operating range and 3.0 V to 5.5 V supply make it useful for non-safety-critical harsh-environment electronics. The MCU can coordinate sensors, relays, and communication links through its 10-bit ADC, timers, UARTs, SPI, I2C, and CAN interface. Automotive qualification is not established by the product summary, so do not treat the temperature rating as AEC-Q100 approval. Qualification, EMC, transient immunity, and functional-safety requirements must be assessed independently for the finished module.

Заметки по проектированию
Place a 100 nF ceramic bypass capacitor at every device supply connection and use the manufacturer recommended bulk capacitance near the power entry. Keep the traces short and pair each supply pin with an adjacent ground return. This arrangement reduces supply impedance and limits digital switching noise coupling into the ADC and communication lines.
Separate analog inputs from switching and high-current digital paths. Route the ADC channels away from clock, CAN, and relay-driver traces, and return analog ground to the MCU ground system at a controlled point. If the analog source has high impedance, add an appropriate RC filter close to the input pin and account for capacitor settling time during sampling.
Do not treat every STM8S device as a footprint-compatible substitute. Compare the complete 44-LQFP pin-description table, alternate functions, exposed power requirements, clock pins, reset behavior, and peripheral availability. The STM8S208S6T3C is a useful evaluation candidate, but firmware, bootloader, and board-level validation remain required before approval.
Size the 3.0 V to 5.5 V supply for the MCU, external transceivers, LEDs, and actuators rather than using the MCU current alone. Check the manufacturer electrical-characteristics table for operating, idle, and peripheral current. Include startup margin for load transients and verify that external CAN or bus transceivers do not push the supply outside its operating limits.
