STMicroelectronics STM8S207K8T6C

Overview

STM8S207K8T6C from STMicroelectronics is a high-performance 8-bit microcontroller featuring an advanced Harvard-architecture core, 64 KB Flash memory, 2 KB data EEPROM, 6 KB RAM, 10-bit ADC with 16 channels, two UARTs (one CAN-capable), SPI, I²C, and a 24 MHz max CPU frequency with zero wait states up to 16 MHz. It integrates a beCAN 2.0B controller and supports LIN 2.1 for automotive body electronics and industrial control nodes.

For engineers reviewing the STM8S207K8T6C datasheet, STM8S207K8T6C pinout, STM8S207K8T6C application, or STM8S207K8T6C equivalent, key selection considerations include its LQFP32 package with 25 I/Os, single-wire interface module (SWIM) debug support, 2.95–5.5 V operation, low-power modes (wait/active-halt/halt), and integrated 16 MHz RC oscillator with user trimming capability.

Technical Context

The STM8S207K8T6C implements a 3-stage pipelined STM8 core with extended instruction set and nested interrupt controller supporting 32 interrupts and up to 37 external IRQs on 6 vectors. Its clock system combines internal 16 MHz RC (trimmable), 128 kHz low-power RC, and external crystal/resonator inputs, backed by clock security monitoring.

Peripheral integration includes TIM1 (16-bit advanced timer with dead-time insertion and complementary outputs), TIM2/TIM3 (16-bit general-purpose timers), TIM4 (8-bit basic timer), auto-wakeup timer, window/independent watchdogs, and dual UARTs - one with LIN master/slave and automatic resynchronization, the other with synchronous clock output.

FAQ

What debug interface does STM8S207K8T6C support?

The STM8S207K8T6C uses the Single Wire Interface Module (SWIM), a proprietary ST protocol requiring only one dedicated pin (PC0) for full in-circuit programming and real-time debugging. It replaces traditional JTAG/SWD and supports flash erase, read, write, breakpoint setting, and register inspection without external debug probes beyond a basic SWIM adapter.

Does STM8S207K8T6C include a hardware CAN controller?

Yes - it integrates a fully compliant beCAN 2.0B controller supporting bit rates up to 1 Mbit/s, message filtering, three transmission mailboxes, two reception FIFOs, and automatic retransmission. It requires only an external CAN transceiver (e.g., TJA1042) to connect to the physical bus, with dedicated PB4 (CAN_RX) and PB5 (CAN_TX) pins.

What is the maximum operating temperature range for this device?

The STM8S207K8T6C is specified for industrial temperature range: –40 °C to +85 °C ambient. All electrical characteristics - including Flash write/erase endurance, ADC accuracy, and oscillator stability - are guaranteed across this range, with thermal derating applied above 70 °C for sustained high-current I/O operation.

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

Yes - the internal 16 MHz RC oscillator includes a 7-bit trimming register (CLK_ICKCR) allowing ±1% fine-tuning across process and voltage variations. Calibration is performed once during production or field programming using a known reference (e.g., external crystal or UART baud rate measurement), enabling accurate timing without external clock components.
