Product details
Overview
STM8S207RBT6CTR 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), 128 KB Flash, 2 KB data EEPROM, and integrated CAN 2.0B interface. It delivers up to 20 MIPS and supports automotive-grade industrial control applications with robust I/Os, dual UARTs, SPI, I²C, and 10-bit ADC with 16 channels.
For engineers reviewing the STM8S207RBT6CTR datasheet, STM8S207RBT6CTR pinout, STM8S207RBT6CTR application, or STM8S207RBT6CTR equivalent, key selection considerations include its LQFP64 package, CAN bus integration, SWIM single-wire debug interface, 2.95–5.5 V operation, and support for active-halt/low-power modes in embedded real-time systems.
Technical Context
The STM8S207RBT6CTR implements an advanced STM8 core with 3-stage pipeline and extended instruction set, enabling deterministic execution at up to 24 MHz. Its clock system integrates user-trimmable 16 MHz RC, low-power 128 kHz RC, and external crystal/resonator support with clock security monitoring.
Peripheral architecture includes a beCAN 2.0B controller (1 Mbit/s), two UARTs (one with LIN 2.1 master/slave and automatic resynchronization), SPI (10 Mbit/s), I²C (400 Kbit/s), and three timers: TIM1 (advanced 16-bit with dead-time insertion), TIM2/TIM3 (general-purpose 16-bit), and TIM4 (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 |
|---|---|---|---|
| STM8S207CBT6 | LQFP48 package (7 × 7 mm), 48-pin count, reduced I/O count (38 GPIOs), same core/peripherals but no CAN interface. | Suitable for compact, cost-sensitive designs where CAN is not required and board space is constrained. | Select when CAN is unnecessary and smaller footprint or lower pin count simplifies routing and reduces PCB layer count. |
| STM8S208RBT6 | Same LQFP64 package and pinout, adds EEPROM hardware error correction (ECC), enhanced ADC linearity (±1 LSB INL), and higher Flash endurance (up to 30 kcycles). | Preferred for safety-critical or high-reliability applications requiring certified data integrity and extended program memory lifetime. | Choose when long-term field reliability, EEPROM ECC, or tighter ADC accuracy specifications are mandated by system certification requirements. |
Compared with STM8S207CBT6, the STM8S207RBT6CTR offers CAN integration and higher I/O count in LQFP64; versus STM8S208RBT6, it trades ECC and enhanced ADC for lower cost and broader legacy design compatibility.

FAQ
What is the maximum operating temperature range for STM8S207RBT6CTR?
The STM8S207RBT6CTR is specified for industrial temperature range: –40 °C to +85 °C. Electrical characteristics, including Flash write/erase endurance and ADC accuracy, are guaranteed across this range per datasheet Table 18 and Table 36. No extended temperature grade is offered for this part number.
Does STM8S207RBT6CTR support in-application programming (IAP) of Flash memory?
Yes, the device supports IAP via its built-in Flash programming interface. The bootloader can execute from RAM or protected Flash sectors, allowing firmware updates over UART, CAN, or SPI without external programmer. Full IAP routines and memory protection mechanisms are documented in RM0016 reference manual Section 3.4.
How many CAN message objects does the integrated beCAN controller support?
The beCAN controller supports 16 message objects (mailboxes) with programmable identifiers, masks, and data lengths. Each object can be configured for transmit or receive, with priority arbitration and automatic retransmission on error frames - sufficient for typical automotive body network nodes with ≤10 active signals.
Is the internal 16 MHz RC oscillator factory-calibrated, and what is its accuracy over temperature?
The internal 16 MHz RC oscillator is factory-trimmed to ±1% accuracy at 25 °C and 3.3 V. Over full temperature and voltage range (–40 °C to +85 °C, 2.95–5.5 V), typical variation is ±3.5%, as specified in datasheet Table 33. User trimming via CLK_HSICALR register allows further calibration to ±1% across temperature.
