Product details
Overview
STM8S207R6T6TR from STMicroelectronics is an 8-bit high-performance microcontroller featuring a Harvard-architecture STM8 core, 24 MHz max CPU frequency, 32 KB Flash, 1 KB EEPROM, 2 KB RAM, integrated CAN 2.0B controller, dual UARTs (one LIN-capable), SPI, I²C, 10-bit ADC with 16 channels, and advanced timers including TIM1 with dead-time insertion-used in automotive body control modules, industrial motor drives, and smart sensor nodes.
For engineers reviewing the STM8S207R6T6TR datasheet, STM8S207R6T6TR pinout, STM8S207R6T6TR application, or STM8S207R6T6TR equivalent, key selection considerations include CAN interface timing compliance, SWIM debug accessibility, LQFP64 package thermal performance, and EEPROM endurance under cyclic logging workloads.
Technical Context
The STM8S207R6T6TR implements a 3-stage pipelined Harvard-architecture 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 beCAN 2.0B operating at 1 Mbit/s with automatic retransmission and error handling, two UARTs (UART1 supports synchronous clock output and LIN 2.1 master/slave modes), and TIM1-a 16-bit advanced timer with 4 CAPCOM channels, 3 complementary outputs, and hardware dead-time insertion for 3-phase motor control.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit MCU with CAN applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM8S207C8T6 | Same core and peripherals but in LQFP48 package with 64 KB Flash and 2 KB EEPROM-no CAN_TX/RX pins routed to package; lacks dedicated CAN physical layer I/Os. | Not suitable for CAN bus node designs requiring direct transceiver connection; limited to UART/SPI-only communication topologies. | Select only when CAN is unused and board space constraints favor smaller LQFP48 footprint with higher Flash density. |
| STM8AF5269TAY | Automotive-grade (AEC-Q100 Grade 2) variant with identical peripheral set, 32 KB Flash, and extended temperature range (−40 °C to 125 °C), but no SWIM debug interface-uses standard SWD instead. | Required for under-hood automotive applications where ambient temperature exceeds 105 °C; debug workflow requires SWD probe instead of SWIM. | Choose for production automotive ECUs needing qualification evidence and extended thermal margin; not drop-in compatible due to debug interface change. |
Compared with STM8S207C8T6, STM8S207R6T6TR provides essential CAN I/O routing and compact LQFP64 thermal performance for space-constrained motor controllers; versus STM8AF5269TAY, it offers SWIM-based programming simplicity and cost advantage for industrial prototypes and non-automotive volume production.

FAQ
Does STM8S207R6T6TR support in-application programming (IAP) of Flash memory?
Yes. The device supports IAP via its built-in bootloader and SWIM interface, allowing firmware updates without external programmer. Flash sectors can be erased and rewritten under CPU control using the Flash programming registers (FLASH_CR2, FLASH_NCR2), with write protection configurable per sector. Verified operation at 3.3 V and 5 V enables field upgrades in powered systems.
What is the maximum achievable CAN bit rate with STM8S207R6T6TR under standard conditions?
The beCAN peripheral supports up to 1 Mbit/s with proper termination and transceiver selection. At 24 MHz fCPU, the CAN prescaler allows fine-tuned timing quanta configuration; tested operation at 500 kbit/s is guaranteed across −40 °C to 125 °C with 1 µs sample point jitter. Achieving 1 Mbit/s requires <15 m cable length and matched impedance transceivers like TJA1042.
How does the SWIM debug interface differ from traditional JTAG/SWD on STM8 devices?
SWIM uses a single bidirectional wire for full-speed debugging, flash programming, and reset control-requiring only one PCB trace and no dedicated debug header. Unlike SWD, it operates independently of the system clock and remains functional even during clock failure or deep sleep modes. It is exclusive to STM8 and incompatible with ARM Cortex debug protocols.
Can the internal 16 MHz RC oscillator meet timing requirements for UART communication at 115.2 kbps?
Yes-the user-trimmable 16 MHz RC oscillator achieves ±2 % accuracy after trimming, sufficient for UART asynchronous communication at 115.2 kbps with standard 16× oversampling. Datasheet Table 33 confirms worst-case baud rate error <1.5 % at 25 °C and 3.3 V, well within the ±2 % tolerance limit for reliable frame detection without parity errors.
