Product details
Overview
STM8S207K6T6C from STMicroelectronics is an 8-bit high-performance microcontroller featuring a Harvard-architecture STM8 core, 24 MHz max CPU frequency, 32 KB Flash, 2 KB data EEPROM, 2 KB RAM, integrated CAN 2.0B controller, 10-bit ADC with 16 channels, and dual UARTs - deployed in automotive body control modules for LIN/CAN gateway functions.
For engineers reviewing the STM8S207K6T6C datasheet, STM8S207K6T6C pinout, STM8S207K6T6C application, or STM8S207K6T6C equivalent, key selection criteria include CAN/LIN coexistence, SWIM debug interface compatibility, LQFP32 package footprint constraints, and industrial temperature-grade (-40°C to +85°C) operation under 2.95–5.5 V supply.
Technical Context
The STM8S207K6T6C 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, low-power 128 kHz RC, and crystal oscillator with clock security monitoring.
Peripheral integration includes beCAN 2.0B (1 Mbit/s), two UARTs (one with LIN 2.1 master/slave support), SPI (10 Mbit/s), I²C (400 kbit/s), 16-bit advanced timer TIM1 with dead-time insertion, and dual 16-bit general-purpose timers - all individually clock-gatable via CLK_PCKENR registers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM8S207C8T6 | LQFP48 package, 64 KB Flash, same peripherals and clock architecture - larger footprint and higher memory capacity. | Preferred where additional Flash/RAM is needed for complex bootloader or OTA update logic; not pin-compatible with LQFP32. | Select when board layout allows 48-pin package and >32 KB code size is required; verify PCB pad layout and thermal dissipation. |
| STM8AF5269TAY | Automotive-grade (AEC-Q100 Grade 2), same LQFP32 package, identical peripheral set but qualified for -40°C to +125°C operation. | Required for under-hood automotive applications; includes enhanced ESD/EMC robustness and extended qualification testing. | Choose for safety-critical or engine-compartment deployments; expect higher unit cost and longer lead times than industrial-grade STM8S207K6T6C. |
Compared with STM8S207C8T6, the STM8S207K6T6C saves board area and BOM cost in space-constrained designs; versus STM8AF5269TAY, it offers lower cost and faster availability for non-automotive-qualified industrial use cases.

FAQ
Does STM8S207K6T6C support hardware CRC calculation?
No, the STM8S207K6T6C 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 (2 KB) to execute efficient software CRC with minimal latency impact on real-time tasks.
What is the maximum allowed crystal frequency for the HSE oscillator?
The HSE oscillator supports external crystal frequencies from 1 to 24 MHz, with recommended operation between 4 and 16 MHz for optimal stability and startup time. At 24 MHz, the device achieves its maximum 24 MHz CPU frequency with zero wait states, provided VDD ≥ 4.5 V per electrical characteristics Table 18.
Can UART3 be used simultaneously with CAN on STM8S207K6T6C?
Yes, UART3 and CAN operate independently and can be used concurrently. They share no common clock sources or DMA channels in the LQFP32 configuration; UART3 uses PC4/PC5 pins while CAN uses PC3/PC4 - requiring careful pin remapping to avoid conflict on PC4 (default CAN_RX overlaps UART3_TX).
Is the internal 128 kHz RC oscillator accurate enough for RTC applications?
No - the internal 128 kHz RC oscillator has ±40% initial tolerance and significant temperature/voltage drift, making it unsuitable for real-time clock (RTC) functions requiring timekeeping accuracy. For RTC, an external 32.768 kHz crystal connected to OSC32_IN/OSC32_OUT pins is required; the STM8S207K6T6C does not integrate a dedicated RTC peripheral.
