STMicroelectronics STM8S207C6T3

Overview

STM8S207C6T3 from STMicroelectronics is an 8-bit high-performance microcontroller featuring a Harvard-architecture STM8 core, 32 KB Flash memory, 2 KB data EEPROM, 2 KB RAM, 10-bit ADC with 10 channels, two UARTs (one CAN-capable), SPI, I²C, and advanced timers including TIM1 with dead-time insertion. It operates up to 24 MHz at 2.95–5.5 V and targets automotive body electronics and industrial control nodes requiring CAN bus integration and robust I/O.

For engineers reviewing the STM8S207C6T3 datasheet, STM8S207C6T3 pinout, STM8S207C6T3 application, or STM8S207C6T3 equivalent, key selection criteria include CAN 2.0B compliance, SWIM single-wire debug interface, 18 high-sink I/Os, 300 kcycle EEPROM endurance, and LQFP48 package compatibility with industrial temperature range (–40°C to +85°C).

Technical Context

The STM8S207C6T3 implements a 3-stage pipelined STM8 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 monitor.

Peripheral subsystems include beCAN 2.0B controller (1 Mbit/s), dual UARTs with LIN 2.1 support, 10 Mbit/s SPI, 400 kbit/s I²C, and a 16-bit advanced control timer (TIM1) with 3 complementary outputs and programmable dead-time - enabling precise motor gate drive and power conversion timing.

FAQ

Does STM8S207C6T3 support in-system programming via SWIM?

Yes. The STM8S207C6T3 supports full in-system programming (ISP) and debugging through its single-wire SWIM interface using standard ST-LINK/V2 or compatible programmers. No bootloader code is required - the SWIM module is hardwired into the silicon and accessible even when the application firmware is corrupted.

What is the maximum achievable CAN bit rate and under what conditions?

The beCAN controller supports up to 1 Mbit/s bit rate with proper termination and cable length ≤ 40 m in standard mode. At 24 MHz fCPU, the CAN prescaler allows fine-tuned timing quanta configuration; typical operation at 500 kbit/s is validated across –40°C to +85°C with ±1% oscillator tolerance using the internal 16 MHz RC trimmed to ±0.5%.

How many ADC channels are physically available on the LQFP48 package?

The LQFP48 package exposes 10 ADC input channels: PA0–PA7 (8 channels), plus PC0 and PC1. All 10 channels are simultaneously accessible in single-conversion or scan mode, with configurable sampling time and hardware trigger sources including TIM1/TRGO and external events.

Is the 2 KB data EEPROM truly wear-leveled or managed in firmware?

The 2 KB data EEPROM is implemented as a dedicated silicon block with hardware wear-leveling logic. Each write cycle automatically rotates pages to distribute erase stress; no firmware intervention is needed. Endurance is guaranteed at 300 kcycles per byte, verified per JEDEC JESD22-A117 standard.
