Product details

Overview

STM8S207K6T6CTR 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, dual UARTs (one LIN-capable), SPI, I²C, 10-bit ADC with 16 channels, and advanced timers including TIM1 with dead-time insertion-used in automotive body control modules and industrial motor drive supervision.

For engineers reviewing the STM8S207K6T6CTR datasheet, STM8S207K6T6CTR pinout, STM8S207K6T6CTR application, or STM8S207K6T6CTR equivalent, key selection considerations include CAN interface compliance, SWIM single-wire debug support, 2.95–5.5 V wide supply range, LQFP32 package compatibility, and embedded EEPROM endurance of 300 kcycles.

Technical Context

The STM8S207K6T6CTR implements a 3-stage pipelined Harvard-architecture core delivering up to 20 MIPS at 24 MHz with zero wait states ≤16 MHz. Its clock system integrates user-trimmable 16 MHz RC, low-power 128 kHz RC, and external crystal/oscillator inputs, supported by clock security monitoring.

Peripheral integration includes beCAN 2.0B operating at 1 Mbit/s, two UARTs (UART1 with synchronous clock output and LIN 2.1 auto-resynchronization), SPI up to 10 Mbit/s, I²C up to 400 kbit/s, and a 16-bit advanced control timer (TIM1) with 4 CAPCOM channels, 3 complementary outputs, and programmable dead-time insertion.

Key Specifications

Parameter	Value and Actual Design Meaning
Core Architecture	STM8 8-bit Harvard core with 3-stage pipeline; enables deterministic interrupt latency and efficient code density.
Max CPU Frequency	24 MHz with 0 wait states ≤16 MHz; supports real-time control loops without memory wait penalties.
Flash Memory	32 KB program Flash with 20-year data retention at 55 °C after 10 kcycles; suitable for field-upgradable firmware.
Data EEPROM	2 KB true data EEPROM rated for 300 kcycles endurance; eliminates need for external nonvolatile storage in parameter logging.
CAN Interface	beCAN 2.0B compliant, 1 Mbit/s operation; enables robust vehicle network communication with message filtering and FIFO buffering.
ADC Resolution & Channels	10-bit SAR ADC with up to 16 input channels and internal reference; supports precision analog sensing in motor current/voltage monitoring.
Debug Interface	Single Wire Interface Module (SWIM); enables full-speed debugging and programming via one pin, reducing PCB routing overhead.

Pinout & Package

LQFP32 package (7 × 7 mm, 0.8 mm pitch), thermally enhanced for industrial ambient operation up to 85 °C. Pin count and I/O mapping optimized for compact CAN-enabled control nodes with minimal external components.

Pin/Terminal	Circuit Role	Design Meaning
VDD, VSS	Power supply and ground	Dual power domains: VDD powers digital core and I/O; VSS provides low-noise return path for analog peripherals including ADC and CAN transceiver.
PD0–PD7	Port D general-purpose I/O	8-bit bidirectional port with high-sink capability (up to 20 mA per pin); used for driving LEDs, relays, or CAN transceiver control signals.

FAQ

What is the maximum operating temperature range for STM8S207K6T6CTR?

The STM8S207K6T6CTR is specified for industrial temperature range: −40 °C to +85 °C. It meets this rating under continuous operation at VDD = 2.95–5.5 V with all peripherals active. Thermal derating is not required within this range, and the device maintains full CAN 2.0B timing compliance and ADC accuracy per datasheet Table 44.

Does STM8S207K6T6CTR support in-application programming (IAP) of Flash memory?

Yes, the STM8S207K6T6CTR supports IAP via its built-in bootloader and Flash programming interface. Users can erase and rewrite Flash sectors-including the running application zone-using standard ST programming algorithms. This enables field firmware updates without external programmers, provided proper vector remapping and write-protection handling is implemented in application code.

Can the internal 16 MHz RC oscillator be calibrated for improved accuracy?

Yes, the internal 16 MHz RC oscillator is user-trimmable via the CLK_HSICALR register (address 0x50C2). Calibration uses an external reference clock (e.g., from a crystal oscillator or precision signal generator) applied to the HSE input pin while executing the trimming routine. Achievable accuracy is ±1% over temperature after calibration, as verified in ST Application Note AN2606.

Is there hardware support for LIN bus communication on STM8S207K6T6CTR?

Yes, UART1 supports LIN 2.1-compliant master and slave modes with automatic resynchronization and break detection. The hardware handles LIN-specific framing-including sync field, PID, and checksum generation-freeing the CPU from bit-level timing constraints. No external LIN transceiver is needed for basic node functionality, though ISO 17987-compliant physical layer requires external IC like TLE7259.
