Product details
Overview
STM8S207C6T6 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, and integrated CAN 2.0B interface. It delivers 20 MIPS at 24 MHz, supports LIN master/slave modes, and targets automotive body control modules, industrial sensor nodes, and smart appliance controllers.
For engineers reviewing the STM8S207C6T6 datasheet, STM8S207C6T6 pinout, STM8S207C6T6 application, or STM8S207C6T6 equivalent, key selection considerations include its 48-pin LQFP package, 10-bit ADC with 16 channels, dual UARTs (one CAN-capable), SWIM single-wire debug interface, and support for active-halt/low-power operation down to 128 kHz RC clock.
Technical Context
The STM8S207C6T6 implements an advanced 3-stage pipelined STM8 core with extended instruction set and nested interrupt controller supporting 32 interrupts and up to 37 external IRQs on 6 vectors. Its clock system integrates user-trimmable 16 MHz RC, low-power 128 kHz RC, and crystal oscillator with clock security monitoring.
Peripheral integration includes a beCAN 2.0B controller (1 Mbit/s), two UARTs (one with LIN 2.1 compliance and auto-resync), SPI (10 Mbit/s), I²C (400 Kbit/s), 16-bit advanced timer (TIM1) with dead-time insertion and complementary outputs, plus two 16-bit general-purpose timers and one 8-bit basic timer.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM8S207M8T6 | 64-pin LQFP, 64 KB Flash, same peripherals and clock architecture; larger memory and I/O count. | Suitable for designs requiring >32 KB code space or >38 GPIOs, e.g., multi-sensor fusion hubs with local display. | Select when scaling firmware complexity or adding USB/SDIO interfaces not supported on C6 variant. |
| STM8AF5269TAY | Automotive-grade (AEC-Q100 Grade 2), identical peripheral set but qualified for -40°C to 125°C operation; same 48-pin LQFP. | Required for under-hood automotive applications where ambient temperature exceeds 105°C. | Choose only if full automotive qualification and extended temperature range are mandatory; otherwise, STM8S207C6T6 offers lower cost and identical functionality. |
Compared with STM8S207M8T6, the C6T6 saves board space and cost in fixed-function applications; compared with STM8AF5269TAY, it trades automotive qualification for broader commercial availability and lower unit price in non-automotive industrial use cases.

FAQ
Does STM8S207C6T6 support in-system programming via SWIM?
Yes. The STM8S207C6T6 supports full in-system programming and debugging through its single-wire SWIM interface, which requires only one dedicated pin (SWIM) and ground. It enables flash erase/write, RAM inspection, and breakpoint execution without halting the main application, and is compatible with ST-LINK/V2 and third-party SWIM programmers.
What is the maximum operating temperature range for STM8S207C6T6?
The STM8S207C6T6 is specified for industrial temperature range: –40 °C to +85 °C. Electrical characteristics-including Flash write/erase endurance, ADC accuracy, and I/O drive strength-are guaranteed across this full range per datasheet Table 18 and Table 10.3. It is not qualified to AEC-Q100 automotive standards.
Can the internal 16 MHz RC oscillator be calibrated for improved accuracy?
Yes. The internal 16 MHz RC oscillator features user-trimmable calibration via the CLK_SWCR register, allowing adjustment in ±1% steps across a ±10% total range. Calibration is typically performed once at production test using an external reference clock, achieving ±1% accuracy over temperature and voltage-sufficient for UART and SPI timing without crystal.
How many CAN message objects does the beCAN peripheral support?
The beCAN controller in STM8S207C6T6 supports 16 message objects (mailboxes) with programmable identifiers, masks, and data lengths. Each object can be configured as transmit or receive, with priority arbitration and automatic retransmission on error frames-meeting full CAN 2.0B specification requirements for embedded network nodes.
