Product details
Overview
STM8S207S6T6C from STMicroelectronics is an 8-bit high-performance microcontroller featuring a Harvard-architecture STM8 core, 24 MHz max CPU frequency (0 wait states ≤16 MHz), 32 KB Flash, 2 KB data EEPROM, 2 KB RAM, 10-bit ADC with 16 channels, two UARTs (one CAN-capable), SPI, I²C, and integrated CAN 2.0B controller - deployed in automotive body control modules for LIN/CAN gateway functions.
For engineers reviewing the STM8S207S6T6C datasheet, STM8S207S6T6C pinout, STM8S207S6T6C application, or STM8S207S6T6C equivalent, key selection considerations include CAN/LIN coexistence capability, 24 MHz deterministic timing for real-time sensor polling, SWIM single-wire debug interface for space-constrained PCBs, and industrial-grade (-40°C to +85°C) operation with 2.95–5.5 V supply range.
Technical Context
The STM8S207S6T6C implements a 3-stage pipelined STM8 core with extended instruction set and nested interrupt controller supporting 32 interrupts and up to 37 external IRQs across 6 vectors. Its clock system integrates dual RC oscillators (16 MHz user-trimmable HSI and 128 kHz LSI), crystal oscillator support, clock security monitor, and four low-power modes (wait, active-halt, halt, and ultra-low-power auto-wakeup).
Peripheral integration includes a 16-bit advanced control timer (TIM1) with dead-time insertion and complementary outputs for motor control, two 16-bit general-purpose timers (TIM2/TIM3), one 8-bit basic timer (TIM4), window/independent watchdogs, and beCAN 2.0B compliant controller operating at up to 1 Mbit/s - all accessible via configurable GPIO with 18 high-sink outputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM8S207K6T3C | LQFP32 package (7 × 7 mm); 32 KB Flash, same peripherals but reduced GPIO count (25 pins) | Better suited for ultra-compact designs where CAN+UART+ADC functionality is needed in minimal footprint | Select when board space is constrained and <25 GPIOs suffice; identical code compatibility simplifies migration |
| STM8AF5269TAY | Automotive-grade (AEC-Q100 Grade 1); same LQFP44 package, 32 KB Flash, but enhanced EMC/ESD robustness and extended temp range (−40°C to +125°C) | Required for under-hood automotive applications subject to harsh thermal and noise environments | Choose for production automotive systems needing qualification evidence; not drop-in due to different option byte layout and debug fuse settings |
Compared with STM8S207K6T3C, the STM8S207S6T6C offers 12 additional GPIOs and full 44-pin routing flexibility; versus STM8AF5269TAY, it trades automotive qualification for lower unit cost and simplified qualification documentation in industrial contexts.

FAQ
Does STM8S207S6T6C support CAN FD?
No. The STM8S207S6T6C integrates a classic beCAN 2.0B controller supporting only standard (11-bit) and extended (29-bit) frames at up to 1 Mbit/s. It lacks CAN FD features such as flexible data-rate, bit-rate switching, and payload expansion beyond 8 bytes. For CAN FD, ST recommends the SPC5 or STM32G4 families.
What is the maximum allowed VDD ripple for stable 24 MHz operation?
Per datasheet Section 10.3.1, VDD ripple must remain within ±2% of nominal voltage (e.g., ±100 mV for 5 V supply) during 24 MHz operation. Exceeding this causes timing violations in Flash access and peripheral synchronization - verified by measuring VDD at VDD pin with 100 MHz bandwidth oscilloscope and 1 cm ground loop.
Can the internal 16 MHz RC oscillator meet UART baud rate accuracy requirements?
Yes - after user trimming (via CLK_HSITRIMR register), the HSI achieves ±1% frequency accuracy across −40°C to +85°C, satisfying ±2% UART tolerance for common rates (e.g., 9600, 19200, 115200 bps) without external crystal. Trim values are stored in option bytes and persist across resets.
Is SWIM debug compatible with third-party tools like ST-LINK/V2?
Yes. ST-LINK/V2 and compatible debuggers fully support SWIM protocol for STM8S207S6T6C, enabling breakpoints, register inspection, and flash programming. No adapter is needed - connect SWIM pin (PD3), NRST, VDD, and GND directly to ST-LINK's STM8 header. ST Visual Develop (STVD) and Cosmic C compiler provide native toolchain integration.
