Product details
Overview
STM8S207CBT6 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, dual UARTs (including LIN-compliant), SPI, I²C, and active beCAN 2.0B interface - deployed in automotive body control modules, industrial motor drives, and smart sensor nodes.
For engineers reviewing the STM8S207CBT6 datasheet, STM8S207CBT6 pinout, STM8S207CBT6 application, or STM8S207CBT6 equivalent, key selection criteria include CAN bus integration, SWIM single-wire debug support, 68 I/O capability in LQFP80, low-power active-halt mode (0.35 µA typ), and 96-bit unique ID for secure firmware binding.
Technical Context
The STM8S207CBT6 implements a 3-stage pipelined Harvard architecture core with extended instruction set and nested interrupt controller supporting 32 interrupts and up to 37 external vectors. Its clock system integrates user-trimmable 16 MHz RC, low-power 128 kHz RC, and crystal oscillator with clock security monitoring.
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), and a dedicated auto-wakeup timer. The beCAN 2.0B controller supports full CAN protocol handling including message filtering, automatic retransmission, and error confinement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | Harvard, 3-stage pipeline, 20 MIPS @ 24 MHz - enables deterministic real-time execution without instruction/data bus contention. |
| Max Operating Frequency | 24 MHz @ VDD ≥ 3.0 V - delivers full performance with zero wait states up to 16 MHz, critical for time-critical control loops. |
| Flash Memory | 128 KB with 20-year data retention at 55 °C after 10 kcycles - supports field-upgradable firmware with long-term reliability in harsh environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM8S207R8T6 | Same core/peripherals but in LQFP64 (48 I/Os, no CAN RX/TX on PD0/PD1; uses PB0/PB1 instead) | Suitable for space-constrained designs where CAN routing flexibility is acceptable and I/O count ≤ 48 suffices | Select when board layout requires smaller footprint and CAN signal routing can be adapted to alternate pins. |
| STM8S208CBT6 | Adds EEPROM write endurance boost (1M cycles vs 300k), enhanced ESD protection (±4 kV HBM), and extended ADC accuracy (±1 LSB INL) | Better suited for high-reliability metering and medical auxiliary controls requiring certified data integrity | Choose when long-term EEPROM write cycles or tighter ADC linearity are mandatory; otherwise STM8S207CBT6 offers identical functionality at lower cost. |
Compared with STM8S207R8T6, the STM8S207CBT6 provides 20 more I/Os and dedicated CAN pins in LQFP80, enabling denser peripheral integration; versus STM8S208CBT6, it trades minor endurance/accuracy enhancements for cost-sensitive volume production without compromising core control capability.

FAQ
What debug interface does the STM8S207CBT6 support?
The STM8S207CBT6 uses the Single Wire Interface Module (SWIM), a proprietary ST protocol requiring only one bidirectional pin (SWIM) and ground for full in-circuit debugging and programming. It supports breakpoints, register read/write, flash erase/write, and real-time variable monitoring without additional hardware debug probes.
Does the STM8S207CBT6 include hardware CAN protocol handling?
Yes - it integrates a fully autonomous beCAN 2.0B controller with 16 message objects, acceptance filtering, automatic retransmission, and error confinement. The controller handles bit timing, arbitration, CRC calculation, and frame assembly/disassembly in hardware, freeing the CPU for application tasks.
What is the maximum number of I/O pins usable in the LQFP80 package?
The STM8S207CBT6 in LQFP80 provides up to 68 I/O pins, including 18 high-sink outputs capable of driving up to 50 mA each. All pins support alternate functions such as UART, SPI, I²C, and CAN, with remappable peripheral functions via configuration registers.
How does the STM8S207CBT6 manage power in battery-operated applications?
It offers three ultra-low-power modes: Wait (1.3 µA), Active-Halt (0.35 µA), and Halt (0.25 µA), all retaining RAM content and register states. Peripheral clocks can be gated individually, and the auto-wakeup timer or external interrupt can resume operation within 4 µs - ideal for intermittent sensing in wireless nodes.
