Product details
Overview
STM8S207CBT6TR 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 - deployed in automotive body control modules and industrial sensor nodes requiring deterministic real-time response.
For engineers reviewing the STM8S207CBT6TR datasheet, STM8S207CBT6TR pinout, STM8S207CBT6TR application, or STM8S207CBT6TR equivalent, key selection criteria include CAN bus integration, SWIM single-wire debug support, 128 KB Flash endurance (10 kcycles, 20-year retention), 68 I/O count in LQFP80, and dual low-power modes (active-halt/halt) with individual peripheral clock gating.
Technical Context
The STM8S207CBT6TR 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 across 6 vectors. Its clock system integrates user-trimmable 16 MHz RC, 128 kHz low-power RC, and crystal oscillator with clock security monitor.
Peripheral subsystems include an advanced 16-bit TIM1 timer with dead-time insertion and complementary outputs for motor control, two general-purpose 16-bit timers (TIM2/TIM3), an 8-bit basic timer (TIM4), beCAN 2.0B controller operating at up to 1 Mbit/s, and UARTs supporting LIN 2.1 master/slave with automatic resynchronization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | STM8 8-bit Harvard core with 3-stage pipeline and extended instruction set - enables deterministic 20 MIPS @ 24 MHz without wait states below 16 MHz. |
| Max Operating Frequency | 24 MHz fCPU - supports real-time control loops with sub-μs interrupt latency and zero-wait-state execution up to 16 MHz. |
| Memory Configuration | 128 KB Flash (20-year data retention @ 55 °C after 10 kcycles), 2 KB true data EEPROM (300 kcycle endurance), 6 KB RAM - enables field firmware updates and nonvolatile parameter storage. |
| Analog Peripherals | 10-bit ADC with up to 16 input channels and internal reference - suitable for precision sensor signal acquisition in automotive and industrial environments. |
| Communication Interfaces | beCAN 2.0B (1 Mbit/s), 2x UART (LIN 2.1 compliant), SPI (10 Mbit/s), I²C (400 Kbit/s) - provides native vehicle network connectivity and multi-protocol sensor/actuator interfacing. |
| Power Management | 2.95–5.5 V supply range; wait/active-halt/halt low-power modes; individual peripheral clock gating - achieves µA-level standby current while retaining RAM and register state. |

| PD0/PD1 | CAN transceiver interface | Direct connection to external CAN PHY (e.g., TJA1042); PD0 = TX, PD1 = RX - enables full CAN 2.0B protocol stack implementation without external level-shifting. |
Key Features
| Feature | Design Value |
|---|---|
| beCAN 2.0B controller | Integrated CAN bus controller supporting 1 Mbit/s bit rate, message filtering, and FIFO buffering - eliminates external CAN controller IC and reduces system latency. |
| SWIM debug interface | Single-pin, non-intrusive in-circuit debugging and flash programming - enables production programming and field firmware updates without dedicated debug headers. |
| Advanced TIM1 timer | 16-bit timer with 4 CAPCOM channels, 3 complementary outputs, and programmable dead-time insertion - supports 3-phase motor control and digital power supply PWM generation. |
| True data EEPROM | 2 KB on-chip EEPROM with 300 kcycle endurance and 20-year data retention - replaces external serial EEPROM, simplifying design and improving reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM8S208CBT6 | Same package and pinout; adds 2x additional UARTs and enhanced ADC trigger flexibility - no CAN controller. | Better suited for multi-serial gateway designs without CAN requirements; lacks vehicle network capability. | Select when CAN is unnecessary and extra UARTs simplify RS-485/RS-232 bridging. |
| STM32F042F6P6 | 32-bit ARM Cortex-M0 core; 48 MHz max, 32 KB Flash, no integrated EEPROM, USB 2.0 FS, but no CAN. | Higher compute throughput for algorithmic tasks; requires external EEPROM for nonvolatile storage; no native CAN support. | Choose for USB-connected devices needing richer firmware features, accepting added BOM complexity for EEPROM and CAN PHY. |
Compared with STM8S208CBT6, STM8S207CBT6TR trades UART count for CAN 2.0B - critical for automotive networks. Versus STM32F042F6P6, it offers lower power, integrated EEPROM, and CAN at the expense of 32-bit performance and USB - making it optimal for cost-sensitive, CAN-dependent embedded control.

FAQ
What is the maximum operating temperature range for STM8S207CBT6TR?
The STM8S207CBT6TR is qualified for industrial temperature range: –40 °C to +85 °C. This rating is validated per ST's qualification standard AEC-Q100 stress tests for humidity, thermal cycling, and high-temperature operating life - ensuring reliability in under-hood automotive and factory-floor industrial environments.
Does STM8S207CBT6TR support in-system programming via SWIM?
Yes. The STM8S207CBT6TR supports full in-system programming and debugging through its Single Wire Interface Module (SWIM) using only one dedicated pin (SWIM). It enables flash memory erase/write, option byte configuration, and real-time variable inspection without halting CPU execution - compatible with ST-LINK/V2 and third-party SWIM programmers.
How many CAN message objects does the integrated beCAN controller support?
The beCAN controller in STM8S207CBT6TR supports 16 message objects (mailboxes) with configurable acceptance filters and priority arbitration. Each object can be configured for transmit, receive, or self-test mode - sufficient for implementing ECUs with up to 8 unique CAN identifiers and concurrent Tx/Rx operations in automotive body networks.
Is the 2 KB data EEPROM truly independent of Flash memory?
Yes. The 2 KB data EEPROM is physically separate from the 128 KB program Flash, with dedicated control logic, erase/write circuitry, and endurance rating (300 kcycles vs. 10 kcycles for Flash). It supports byte-wise write and page-wise erase, retains data for 20 years at 55 °C, and operates independently during Flash programming - enabling safe runtime parameter storage.
