STM8S207RBT6C - 24MHz 8-Bit MCU with 128KB Flash | STMicroelectronics
MPN: STM8S207RBT6C ✓ ActiveSTM8S207RBT6C Overview
A microcontroller is a programmable semiconductor device that integrates a CPU core, program memory, data memory, and peripherals into one package. The STM8S207RBT6C belongs to the STM8 8-bit microcontroller hierarchy, where its relatively high operating frequency supports time-sensitive control loops, while 128 KB of Flash provides room for application code, boot logic, communication routines, and field-update capability. The STM8S207RB family spans performance-line devices offering up to 128 KB of Flash program memory.
The key documented configuration is a 24 MHz maximum CPU frequency, 128 KB Flash organized as 128K x 8, an 8-bit architecture, and a 64-LQFP package with a 14 x 14 mm body. The C designation and tape-and-reel ordering suffix should be preserved when purchasing or substituting the part. Exact RAM capacity, peripheral configuration, pin functions, electrical limits, and operating-temperature limits must be confirmed in the manufacturer's product documentation before schematic capture or PCB release.
The STM8S207RBT6C is suited to industrial controllers, compact automation modules, motor-control supervisory systems, appliance-control boards, and connected equipment that benefit from the STM8 8-bit platform. Its 24 MHz clock rate is useful for polling sensors, updating displays, executing state machines, and coordinating real-time I/O while retaining the simple programming model associated with 8-bit embedded control. A design should also verify motor-control, communication, and analog-peripheral requirements against the exact pin and peripheral map before selecting this package.
A key design practice is to assign every external signal and supply connection from the 64-pin package drawing rather than inferring connections from a similarly named STM8S207RBT6. The manufacturer distinguishes the STM8S207RBT6C 14 x 14 mm package from the 10 x 10 mm STM8S207RBT6 package, so these two orderable devices cannot be treated as footprint-compatible. Keep the clock, reset, programming, debug, and decoupling networks within the layout and placement guidance in the manufacturer datasheet.
This product overview combines the exact device identity, package distinction, searchable technical facts, procurement guidance, and replacement cautions with practical design guidance. It also highlights the limits of direct substitution: a valid drop-in alternative must match the 64-LQFP 14 x 14 mm footprint, pin arrangement, memory configuration, clock requirements, peripheral assignments, and electrical constraints rather than merely sharing the STM8S207RB family name.
Drop-in alternatives for STM8S207RBT6C — same package, pin-to-pin compatible. Different-package parts requiring PCB rework are excluded.

Typical Applications
STM8S207RBT6C is suitable for 6 applications: Industrial Automation Controller, Motor-Control Supervisory System, Appliance Control Board, Sensor Hub and Data Logger, Communication Equipment Interface, Connected Embedded Module.
Industrial Automation Controller
The STM8S207RBT6C fits compact automation controllers that require fast I/O handling, deterministic state-machine execution, and room for application code. Its 24 MHz maximum CPU frequency supports sensor polling, actuator coordination, communication servicing, and local diagnostics in a single 8-bit MCU. The 128 KB of Flash is valuable when firmware includes protocol stacks, parameter storage, calibration logic, and field-update routines. Place the controller directly on a 64-LQFP 14 x 14 mm PCB layout and verify every pin and peripheral function against the STM8S207RB documentation before schematic release.
Recommended
Motor-Control Supervisory System
The STM8S207RBT6C can supervise a motor-control subsystem where its 24 MHz 8-bit core executes control sequencing, monitors sensor inputs, and coordinates protection signals. The 128 KB Flash capacity allows organized firmware modules for a state machine, current and position processing, communication commands, and diagnostic logging. The MCU should remain a supervisory controller unless the exact device pinout confirms that all required timer outputs, analog inputs, and protection functions are present. Validate timing margins and thermal behavior with the final power stage and motor environment.
Recommended
Appliance Control Board
The STM8S207RBT6C is suitable for appliance controllers that coordinate relays, sensors, indicators, and user interfaces while retaining substantial firmware space. A 24 MHz 8-bit MCU provides practical execution bandwidth for a multi-state control sequence, debounce logic, display updates, and service diagnostics. Its 128 KB Flash can hold application code alongside communication and update routines. Use the exact 64-LQFP 14 x 14 mm footprint, protect noisy relay and mains domains with the appropriate isolation strategy, and confirm the final operating-temperature and supply requirements for the appliance enclosure.
Recommended
Sensor Hub and Data Logger
The STM8S207RBT6C can act as a local sensor hub for industrial or building equipment when it must acquire inputs, filter readings, and store operational records without a high-power processor. The 24 MHz clock supports timely sensor polling and event handling, while 128 KB of Flash provides room for drivers, filtering code, configuration handling, and communication services. Its 8-bit architecture is most appropriate for moderate data rates and moderate control complexity. Confirm the available timers, serial interfaces, ADC channels, and memory resources in the exact device documentation before assigning the sensing architecture.
Recommended
Communication Equipment Interface
The STM8S207RBT6C is appropriate for a communication-equipment interface that performs protocol framing, configuration management, status reporting, and local control. Its 24 MHz maximum frequency and 128 KB Flash configuration support embedded protocol stacks and field-service logic, while the 8-bit architecture keeps the implementation economical for secondary control tasks. The controller should manage a separate network or radio device rather than assume that unsupported high-speed interfaces are present. Verify UART, SPI, I2C, timer, and interrupt resources against the exact 64-pin pin map.
Recommended
Connected Embedded Module
The STM8S207RBT6C can serve as the local controller in a connected embedded module that handles sensor acquisition, user commands, status indication, and low-speed links. The 128 KB Flash capacity leaves room for protocol handlers, device-state logic, diagnostic counters, and secure update preparation, while the 24 MHz core supports responsive event processing. A wireless or network interface should remain a separate component unless the exact pin and peripheral configuration supports the required link. Confirm standby behavior, supply voltage, clock accuracy, and package-level production details before finalizing the module architecture.

Design Notes
Create the footprint from the STM8S207RBT6C 64-LQFP 14 x 14 mm package drawing, not from STM8S207RBT6. Confirm pad length, pad width, pitch, body clearance, and pin-1 orientation against the manufacturer package information. Place decoupling capacitors beside their associated supply pins with short ground returns, and route clocks, programming signals, and reset away from switching nodes. A mechanical overlay error can create an assembly that appears electrically compatible but cannot be placed safely on the intended board.
Verify the exact supply-voltage range, absolute maximum ratings, and internal peripheral connections before selecting regulators or designing the power tree. The published 24 MHz operating speed does not by itself define permissible clock, voltage, or I/O combinations. Provide local decoupling and controlled ramp behavior, and use the manufacturer’s recommended reset and clock circuitry. If the board connects to motors, relays, or long external cables, add appropriate protection rather than relying on the MCU’s general-purpose I/O pins for energy handling.
Assign signals from the exact ordering code’s pin-description table and keep the 64-pin numbering consistent across schematic, footprint, symbol, and assembly documentation. Separate analog or sensitive sensing paths from digital switching traces where practical, maintain short return paths, and reserve access to the programming interface. Review oscillator placement, clock routing, and debug signals against the STM8S207RB layout guidance. After schematic release, perform a pin-by-pin electrical audit against the final datasheet revision.
Do not treat all STM8S207RB suffixes as interchangeable. STM8S207RBT6C is documented in a 14 x 14 mm LQFP, whereas STM8S207RBT6 is documented in a 10 x 10 mm LQFP. Likewise, STM8S207R8T6 and STM8S207R6T6 have different order codes and must not be described as drop-in substitutes without package, memory, and pin-level validation. Keep the full suffix on purchasing and approved-part records to prevent a mechanically incompatible substitution.
Compliance Information
No explicit compliance declaration was identified for the exact STM8S207RBT6C order code. Confirm RoHS, REACH, halogen-free, and conflict-minerals status from the manufacturer declaration applicable to the ordered device and package.
