STMicroelectronics STM8S207C8T6TR

Overview

STM8S207C8T6TR from STMicroelectronics is an 8-bit high-performance microcontroller featuring a Harvard-architecture STM8 core, 24 MHz max CPU frequency, 64 KB Flash, 2 KB data EEPROM, 6 KB RAM, 10-bit ADC with 16 channels, two UARTs (one CAN-capable), SPI, I²C, and integrated CAN 2.0B controller - deployed in automotive body control modules and industrial motor drives.

For engineers reviewing the STM8S207C8T6TR datasheet, STM8S207C8T6TR pinout, STM8S207C8T6TR application, or STM8S207C8T6TR equivalent, key selection criteria include CAN interface integration, SWIM single-wire debug support, 24 MHz operation at 2.95–5.5 V supply, and LQFP48 package compatibility with legacy STM8S designs.

Technical Context

The STM8S207C8T6TR implements a 3-stage pipelined Harvard-architecture core with extended instruction set and up to 20 MIPS throughput. It integrates a clock security system with monitor, nested interrupt controller supporting 32 interrupts, and dual watchdog timers (window + independent).

Its peripheral suite includes an advanced 16-bit TIM1 timer with dead-time insertion and complementary outputs for motor control, two 16-bit general-purpose timers (TIM2/TIM3), and a beCAN 2.0B controller supporting 1 Mbit/s data rate with message filtering and automatic retransmission.

FAQ

Does STM8S207C8T6TR support in-system programming via SWIM?

Yes. The device supports full in-system programming and real-time debugging through the single-wire SWIM interface using ST-LINK/V2 or compatible programmers. No external bootloader is required - the SWIM module is hardwired to the core and active immediately after reset, enabling firmware updates without removing the MCU from the PCB.

What is the maximum operating temperature range for STM8S207C8T6TR?

The STM8S207C8T6TR is qualified for industrial temperature range: −40 °C to +85 °C. This rating is validated per JEDEC JESD22-A104 and applies to all electrical specifications in the datasheet, including CAN timing, ADC accuracy, and Flash write endurance under thermal stress.

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

Yes. The internal high-speed RC oscillator (HSI) is user-trimmable via the CLK_HSITRIMR register, allowing ±1% fine-tuning across voltage and temperature. Trim values are stored in option bytes and persist across resets, enabling calibration during production test without external crystal dependency.

Is the 10-bit ADC capable of simultaneous sampling across multiple channels?

No. The ADC2 module performs sequential sampling per channel in scan mode. While it supports hardware-triggered conversions and auto-incremented channel selection, true simultaneous sampling requires external analog multiplexers or dedicated dual ADC silicon not present in this device.
