STM8S207K6T3C - 24MHz 8-Bit MCU | STMicroelectronics
Référence : STM8S207K6T3C ✓ ActifSTM8S207K6T3C Présentation
An STM8 microcontroller is an 8-bit embedded controller in the semiconductor and microcontroller hierarchy. The STM8S207K6T3C combines an advanced STM8 Harvard-architecture core with integrated analog and communications functions, allowing a compact control design to avoid adding separate interface ICs. Its 24 MHz operating frequency and zero-wait-state operation at 16 MHz support responsive control tasks, while the Harvard architecture separates program and data access paths.
The device combines a 10-bit ADC with timers, two UARTs, SPI, I²C, and CAN connectivity. A 3 V to 5.5 V supply range allows use in industrial, consumer, instrumentation, communications, and embedded-control equipment. Its 38 I/O ports provide external connections for sensors, actuators, human-interface devices, status indicators, and bus nodes. The integrated EEPROM supports nonvolatile parameter storage without requiring an external memory component.
The K6 configuration provides 32 KB of Flash program memory, distinguishing it from higher-density members of the STM8S207 family. The manufacturer identifies the STM8S20x family as a performance line spanning 32 KB to 128 KB of Flash memory. This balance of memory, connectivity, and processing speed makes the part appropriate for compact products that need multiple serial interfaces without the footprint and cost of a larger general-purpose MCU.
Typical uses include CAN-connected industrial controllers, motor and actuator control systems, instrumentation, communication equipment, and compact embedded platforms. Two UARTs can support diagnostic or configuration links, SPI can accommodate faster peripherals or memory, and I²C supports sensors and configuration devices. CAN is useful when the controller must participate in a multidrop industrial network or communicate with another embedded subsystem.
When laying out the board, follow the manufacturer’s pin-description table and package drawing when assigning the 38 I/O ports and power pins. Keep decoupling capacitors close to the supply pins, route high-current returns directly to the ground plane, and confirm clock, reset, programming, and communication signal routing against the device documentation. Adequate exposed-board area around the LQFP package improves heat transfer.
This product page combines the manufacturer’s family information with practical interface-selection guidance, verified lifecycle information, same-package replacement analysis, and engineering guidance for evaluating the STM8S207K6T3C in embedded-control systems.

Applications typiques
STM8S207K6T3C convient pour 6 applications: CAN-Connected Industrial Control, Motor and Actuator Control, Industrial Instrumentation, Communication Equipment, Sensor and Condition Monitoring, Embedded Control and HMI.
CAN-Connected Industrial Control
The STM8S207K6T3C fits compact industrial controllers because it combines a 24 MHz 8-bit core, 32 KB of Flash, integrated EEPROM, 38 I/O ports, and a dedicated CAN interface. It can manage actuator outputs, read discrete inputs, retain configuration data, and exchange cyclic control information over the same device. The 10-bit ADC also supports basic analog supervision without requiring a separate converter. The practical trade-off is that 32 KB of Flash may constrain large protocol stacks or complex diagnostic routines, making the 64 KB STM8S207K8T6C worth evaluating when firmware headroom is needed.
Recommandé
Motor and Actuator Control
The STM8S207K6T3C is appropriate for small motor, valve, relay, and actuator control modules where deterministic embedded timing and multiple interfaces are useful. Its integrated timers support periodic control tasks, while the 38 I/O ports can accommodate position sensors, switches, status LEDs, and driver-control signals. A 24 MHz clock provides useful execution headroom for closed-loop routines and communications. The trade-off is that the 32 KB Flash footprint should be monitored closely when combining fieldbus protocols, logging, and safety routines; a larger-code STM8S207 family member may provide more room.
Recommandé
Industrial Instrumentation
The STM8S207K6T3C can serve as the acquisition and control center in compact instrumentation because it combines a 10-bit ADC with 38 I/O ports, EEPROM, timers, and serial connectivity. The ADC can process analog sensor signals, while the integrated EEPROM can retain calibration constants and configuration records. Two UARTs allow simultaneous use for a local console and an external host, and SPI offers a faster path to displays, converters, or memory. Designers must account for analog-noise control, reference accuracy, and input-impedance requirements, while confirming that 32 KB of Flash accommodates calibration, filtering, and communications firmware.
Recommandé
Communication Equipment
The STM8S207K6T3C fits communication modules that need several serial paths without a high-end processor. Two UARTs support external modems, service ports, or peer devices; I²C handles sensors and configuration peripherals; SPI supports faster converters or storage; and CAN supports networked equipment. The 24 MHz CPU and three-stage Harvard architecture provide the execution speed for protocol framing and supervisory logic. Its 32 KB Flash limit is the main constraint, so firmware size should be measured early, and the 64 KB STM8S207K8T6C should be considered when buffers, diagnostics, or multiple protocol stacks increase firmware demand.
Recommandé
Sensor and Condition Monitoring
The STM8S207K6T3C supports compact condition-monitoring products that combine sensor acquisition, local processing, and remote reporting. Its 10-bit ADC handles suitable analog sensors, while digital inputs, timers, and three communication interfaces allow synchronized sampling and communication with a gateway. Integrated EEPROM can retain thresholds, calibration values, and counters across power cycles. Because the converter is 10-bit rather than higher resolution, applications requiring fine analog discrimination should include suitable filtering and signal conditioning. Firmware capacity must also be checked for storage, alarms, logging, and communications.
Recommandé
Embedded Control and HMI
The STM8S207K6T3C is useful in compact embedded-control products with local switches, indicators, displays, and programmable outputs. Its 38 I/O ports leave substantial interface capacity, and the 24 MHz core can execute keypad or display tasks alongside control logic. SPI or I²C can connect an efficient display or input controller, while UART provides a service or configuration channel. The 32 KB Flash configuration favors focused firmware, so complex graphical interfaces and extensive libraries should trigger evaluation of the 64 KB STM8S207K8T6C. PCB planning should follow the LFQP pin drawing and preserve clean grounding for attached display and switching circuits.

Principaux différenciateurs
- Matches the STM8S207K6 memory configuration while providing a direct same-package replacement candidate (vs STM8S207K6T6C)
- Provides twice the program memory for firmware expansion without changing the family CPU speed (vs STM8S207K8T6C)
- Integrates the full control peripheral set in one 48-pin device (vs STM8S207K8T6C)
Notes de conception
Assign every net from the STM8S207K6 manufacturer pin-description table rather than inferring connections from the 38 I/O count. Keep power bypass capacitors adjacent to the relevant supply and ground pins, provide a continuous ground plane beneath and around the LQFP, and route clock and programming signals away from switching nodes. The exposed underside of the 48-pin LQFP is not equivalent to an exposed-pad thermal land, so thermal improvement should come primarily from PCB copper and the manufacturer’s recommended layout.
Design the 3 V to 5.5 V supply for the MCU plus all attached peripherals rather than sizing it from the nominal CPU voltage alone. Check peak current from the selected regulator and local decoupling recommendations against the device documentation. Place bulk capacitance near the supply entry point and local high-frequency decoupling close to the device pins. If peripherals generate substantial transients, isolate their return currents so they do not flow through sensitive MCU ground paths.
Use the manufacturer’s LFQP package drawing for land pattern and pad assignment, and verify connector orientation before fabrication. CAN, SPI, and I²C lines should have controlled return paths and appropriate terminations where required by the attached bus. Keep the 10-bit ADC inputs away from switching-node traces and provide a clean analog ground strategy when the MCU is the system ADC. Programming and reset nets should remain accessible and free from long unprotected stubs.
Do not assume the STM8S207K8T6C is an identical replacement merely because it belongs to the same performance line. Its 64 KB Flash is twice the STM8S207K6T3C’s 32 KB, and a larger memory size can affect boot, firmware, and update logic even though the clock and peripheral family remain aligned. Likewise, confirm the meaning of every T3 or T6 ordering suffix before substituting a component in a temperature-controlled or safety-related production design.
