Product details
Overview
STM8S207S6T3CTR from STMicroelectronics is an 8-bit high-performance microcontroller featuring a 24 MHz STM8 core, 32 KB Flash memory, 2 KB data EEPROM, 2 KB RAM, integrated CAN 2.0B interface, 10-bit ADC with 16 channels, and dual UARTs - deployed in automotive body control modules for LIN/CAN gateway functions.
For engineers reviewing the STM8S207S6T3CTR datasheet, STM8S207S6T3CTR pinout, STM8S207S6T3CTR application, or STM8S207S6T3CTR equivalent, key selection criteria include CAN/LIN coexistence, SWIM debug support, 2.95–5.5 V operation, and LQFP44 package compatibility with industrial temperature range (−40 to +85 °C).
Technical Context
The STM8S207S6T3CTR implements a Harvard-architecture 8-bit core with 3-stage pipeline and extended instruction set, delivering up to 20 MIPS at 24 MHz with zero wait states ≤16 MHz. Its clock system integrates user-trimmable 16 MHz RC, low-power 128 kHz RC, and external crystal/oscillator inputs with clock security monitoring.
Peripheral integration includes a beCAN 2.0B controller supporting 1 Mbit/s active operation, two UARTs (one with LIN 2.1 master/slave and automatic resynchronization), SPI (up to 10 Mbit/s), I²C (400 kbit/s), and three 16-bit timers - including TIM1 with dead-time insertion and complementary outputs for motor control timing.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM8S207C8T6 | Same core and peripherals, but LQFP48 package with 48 pins and 64 KB Flash - adds 4 extra I/Os and larger program space. | Preferred where additional GPIOs or future firmware expansion headroom is required; not pin-compatible with LQFP44 layout. | Select when board redesign permits larger footprint and higher Flash demand exceeds 32 KB. |
| STM8AF5288 | Automotive-grade (AEC-Q100 Grade 2) variant with identical LQFP44 pinout, 32 KB Flash, and enhanced ESD/EMC robustness. | Required for under-hood or safety-critical automotive applications where qualification to −40 to +125 °C and automotive reliability standards is mandatory. | Choose for production programs requiring AEC-Q100 compliance; otherwise, STM8S207S6T3CTR suffices for cabin/non-safety systems. |
Compared with STM8S207C8T6, the STM8S207S6T3CTR offers optimal cost and size for space-constrained BCU designs; versus STM8AF5288, it trades automotive qualification for lower unit cost and broader commercial availability - enabling faster prototyping and cost-sensitive volume production.

FAQ
Does STM8S207S6T3CTR support hardware CRC calculation?
No. The STM8S207S6T3CTR does not integrate a dedicated CRC computation unit. CRC must be implemented in firmware using the standard STM8 instruction set. Application notes AN2606 and AN4405 provide optimized assembly routines achieving <100 cycles per 16-bit CRC on this device.
What is the maximum allowed crystal frequency for the HSE oscillator?
The HSE oscillator supports external crystals or ceramic resonators from 1 to 24 MHz. For stable 24 MHz operation, ST recommends using a 24 MHz ±100 ppm crystal with load capacitance matching the value specified in the oscillator circuit (typically 12–22 pF), as defined in Section 10.3.3 of the datasheet.
Can the internal 16 MHz RC oscillator be calibrated in-system?
Yes. The internal 16 MHz RC oscillator includes a user-trimmable calibration register (CLK_HSICALR) allowing ±1% fine-tuning via software. Calibration is performed against an external reference (e.g., HSE or precise UART baud rate measurement) and retained across resets - documented in Section 4.5 and Register Map Table 9.
Is the CAN peripheral compatible with ISO 11898-3 (low-speed fault-tolerant CAN)?
No. The beCAN peripheral in STM8S207S6T3CTR complies exclusively with ISO 11898-2 (high-speed CAN). It lacks the dominant/recessive state arbitration and bus fault tolerance required for low-speed implementations. External transceivers like TJA1055 are incompatible; only high-speed transceivers (e.g., TJA1042) may be used.
