Product details
Overview
STM8S207R6T6 from STMicroelectronics is an 8-bit high-performance microcontroller featuring a Harvard-architecture STM8 core, 24 MHz max CPU frequency, 32 KB Flash, 2 KB data EEPROM, 2 KB RAM, integrated CAN 2.0B controller, dual UARTs (one LIN-capable), SPI, I²C, and 10-bit ADC with 16 channels - deployed in automotive body control modules, industrial sensor nodes, and smart HVAC actuators.
For engineers reviewing the STM8S207R6T6 datasheet, STM8S207R6T6 pinout, STM8S207R6T6 application, or STM8S207R6T6 equivalent, key selection considerations include CAN bus integration, SWIM single-wire debug support, 2.95–5.5 V wide supply range, low-power active-halt mode (0.35 µA typ), and LQFP64 package compatibility with legacy STM8S207xx designs.
Technical Context
The STM8S207R6T6 implements a 3-stage pipelined Harvard architecture core with extended instruction set and nested interrupt controller supporting 32 interrupts and up to 37 external IRQ lines across 6 vectors. Its clock system integrates user-trimmable 16 MHz RC, low-power 128 kHz RC, and crystal oscillator with clock security monitor.
Peripheral subsystems include an advanced 16-bit TIM1 timer with dead-time insertion and complementary outputs for motor control, two general-purpose 16-bit timers (TIM2/TIM3), an 8-bit basic timer (TIM4), beCAN 2.0B controller operating at up to 1 Mbit/s, and a 10-bit ADC with hardware-accelerated scan mode across 16 input channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | STM8 8-bit Harvard core with 3-stage pipeline and 20 MIPS @ 24 MHz - enables deterministic real-time execution without wait states below 16 MHz. |
| Flash Memory | 32 KB program Flash with 20-year data retention at 55 °C after 10 kcycles - supports field firmware updates and robust code storage. |
| Data EEPROM | 2 KB true data EEPROM rated for 300 kcycles endurance - provides nonvolatile parameter storage without external serial EEPROM. |
| CAN Interface | beCAN 2.0B compliant controller with 1 Mbit/s max bit rate and message filtering - enables direct integration into automotive and industrial CAN networks. |
| ADC Resolution | 10-bit SAR ADC with up to 16 input channels and hardware-accelerated scan mode - delivers precise analog sensing for multi-sensor systems. |
| Supply Voltage | 2.95 V to 5.5 V operation - allows direct interface with 3.3 V and 5 V logic domains and simplifies power design in mixed-voltage systems. |
| Low-Power Modes | Wait, active-halt (0.35 µA typ), and halt modes with individual peripheral clock gating - extends battery life in portable and remote monitoring applications. |
Pinout & Package
LQFP64 package (10 × 10 mm, 0.5 mm pitch) with 54 general-purpose I/Os, including 18 high-sink outputs capable of 20 mA sink per pin - suitable for driving LEDs, relays, and discrete loads without external buffers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual VDD/VSS pairs ensure stable core and I/O rail decoupling; VCAP pin requires external 1 µF ceramic capacitor for internal regulator stability. |

| SPICLK/MOSI/MISO/NSS | SPI interface signals | Full-duplex SPI up to 10 Mbit/s with software-selectable CPOL/CPHA - interoperable with sensors, displays, and flash memory. |
| SCL/SDA | I²C bus interface | Standard/fast-mode I²C (up to 400 kbit/s) with SMBus timeout and glitch filtering - compatible with temperature, pressure, and EEPROM peripherals. |
| CANRX/CANTX | CAN physical layer interface | Dedicated differential CAN transceiver pins supporting ISO 11898-1; require external CAN transceiver (e.g., TJA1042) for bus connection. |
Key Features
| Feature | Design Value |
|---|---|
| Single-wire interface module (SWIM) | Enables full debug, flash programming, and memory inspection using only one MCU pin - reduces development tooling cost and board space. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM8S207R8T6 | 64 KB Flash, same peripherals and package - doubles program memory capacity without changing pinout or firmware architecture. | Required where bootloader + application firmware exceed 32 KB or future feature expansion is planned. | Select R8T6 when firmware size headroom is critical; maintains full hardware and software compatibility with R6T6. |
| STM8S005K6T3C | 32 KB Flash, 1 KB RAM, no CAN, LQFP32 package - lower-cost, smaller-footprint variant lacking CAN and reduced I/O count (25 pins). | Suitable for non-networked consumer appliances or simple sensor interfaces where CAN is unnecessary. | Choose S005K6T3C only if CAN and >32-pin I/O are not required; not a drop-in replacement due to missing peripherals and package mismatch. |
Compared with STM8S207R6T6, the R8T6 offers scalable firmware headroom within identical hardware constraints, while the S005K6T3C trades CAN and I/O for cost and size reduction - making R6T6 the optimal balance of connectivity, memory, and peripheral richness in LQFP64 form factor.

FAQ
Does STM8S207R6T6 support in-circuit debugging via SWIM?
Yes. The STM8S207R6T6 integrates a Single Wire Interface Module (SWIM) that enables full in-circuit debugging, flash programming, and memory inspection using only one dedicated pin (SWIM). It supports breakpoints, register watch, and live variable monitoring through ST-LINK v2/v3 debug probes and STM8CubeIDE.
What is the maximum operating temperature range for STM8S207R6T6?
The STM8S207R6T6 is specified for industrial temperature range: –40 °C to +85 °C ambient. Electrical characteristics including Flash write/erase endurance, ADC accuracy, and CAN timing compliance are guaranteed across this full range per datasheet Section 10.3.
Can the internal 16 MHz RC oscillator meet UART timing requirements without calibration?
No. The uncalibrated internal 16 MHz RC oscillator has ±10% initial tolerance, exceeding UART baud rate error limits. However, the oscillator supports user trimming via option bytes to achieve ±1% accuracy - sufficient for 115.2 kbps UART and LIN 2.1 master operation across voltage and temperature.
Is external CAN transceiver required for beCAN functionality?
Yes. The STM8S207R6T6 contains only the CAN protocol controller (beCAN); it lacks the physical layer (PHY). An external high-speed CAN transceiver such as the TJA1042T/3 or SN65HVD230 must be used to connect to the CAN bus, with proper termination and ESD protection implemented on the PCB.
