Product details
Overview
STM8S207RBT6TR from STMicroelectronics is an 8-bit high-performance microcontroller featuring a Harvard-architecture STM8 core, 24 MHz max CPU frequency, 128 KB Flash, 2 KB data EEPROM, 10-bit ADC with 16 channels, two UARTs (one CAN-capable), SPI, I²C, and integrated CAN 2.0B controller. It targets automotive body electronics, industrial control panels, and smart sensor nodes requiring robust timing, mixed-signal integration, and LIN/CAN bus connectivity.
For engineers reviewing the STM8S207RBT6TR datasheet, STM8S207RBT6TR pinout, STM8S207RBT6TR application, or STM8S207RBT6TR equivalent, key selection factors include its LQFP64 package with 54 GPIOs, dual UART support with LIN 2.1 master/slave capability, beCAN 2.0B compliance at 1 Mbit/s, 16-bit advanced timer with dead-time insertion, and SWIM single-wire debug interface for space-constrained embedded designs.
Technical Context
The STM8S207RBT6TR implements a 3-stage pipelined Harvard-architecture core delivering up to 20 MIPS at 24 MHz with zero wait states below 16 MHz. Its clock system integrates user-trimmable 16 MHz RC, low-power 128 kHz RC, and external crystal/resonator support, all monitored by a clock security system.
Interrupt handling uses a nested controller supporting 32 vectors and up to 37 external interrupts across six priority levels. Peripheral subsystems include TIM1 (16-bit advanced timer with 3 complementary outputs and dead-time control), TIM2/TIM3 (16-bit general-purpose timers), TIM4 (8-bit basic timer), and auto-wakeup timer - all individually clock-gatable for dynamic power management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM8S207CBT6 | LQFP48 package (32 GPIOs, no CAN); identical core, memory, and peripherals except missing beCAN controller and 6 I/Os. | Suitable for cost-sensitive non-automotive applications where CAN is unnecessary and board space is constrained. | Select when CAN bus is not required and smaller footprint reduces assembly cost - but verify I/O count sufficiency for target design. |
| STM32F042F6P6 | 32-bit ARM Cortex-M0 core, 48 MHz, 32 KB Flash, no integrated EEPROM, USB 2.0 FS, no CAN; higher performance but different toolchain and memory architecture. | Better suited for USB-connected devices or applications needing >20 MIPS throughput, but requires external EEPROM for parameter storage. | Choose for new designs prioritizing future scalability and USB integration - avoid if legacy STM8 codebase reuse or EEPROM persistence is mandatory. |
Compared with STM8S207CBT6, the STM8S207RBT6TR adds CAN 2.0B and 22 additional I/Os in LQFP64; versus STM32F042F6P6, it retains EEPROM, lower power in deep sleep, and simpler migration path from legacy STM8 platforms - critical for automotive Tier-2 suppliers maintaining long-lifecycle programs.

FAQ
Does STM8S207RBT6TR support hardware CRC calculation?
No, the STM8S207RBT6TR does not include a dedicated hardware CRC peripheral. CRC computation must be implemented in firmware using standard polynomial algorithms (e.g., CRC-8 or CRC-16). The device provides sufficient CPU performance (20 MIPS) and RAM (6 KB) to execute CRC routines efficiently within real-time constraints for CAN or bootloader applications.
What is the maximum operating temperature range for STM8S207RBT6TR?
The STM8S207RBT6TR is specified for industrial temperature range: –40 °C to +85 °C. This is confirmed in Section 10.3 ("Operating conditions") of the datasheet (DocID14733 Rev 13), with thermal derating applied above 85 °C ambient. It is not qualified for extended automotive (–40 °C to +125 °C) operation.
Can the internal 16 MHz RC oscillator be used for CAN communication?
No - the internal 16 MHz RC oscillator has ±1% typical accuracy at 25 °C, which exceeds the ±0.5% tolerance required for reliable CAN 2.0B operation at 1 Mbit/s. The datasheet explicitly recommends using the HSE crystal oscillator or external clock source for CAN timing; the RC oscillator is suitable only for non-timing-critical peripherals like UART or SPI at lower baud rates.
Is SWIM debug compatible with ST-LINK/V2 programmers?
Yes, ST-LINK/V2 and later versions (including ST-LINK/V2-1 and ST-LINK/V3) fully support SWIM protocol for programming and debugging STM8S207RBT6TR. No adapter or level shifter is needed - direct connection to SWIM pin (PD3), NRST, VDD, and GND suffices. ST's STM8CubeProgrammer software provides GUI and command-line interfaces for flash programming and option byte configuration.
