Product details
Overview
STM8S208C6T6TR 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, 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 sensor nodes requiring deterministic real-time response.
For engineers reviewing the STM8S208C6T6TR datasheet, STM8S208C6T6TR pinout, STM8S208C6T6TR application, or STM8S208C6T6TR equivalent, key selection criteria include CAN interface integration, SWIM single-wire debug support, 2.95–5.5 V wide supply range, low-power active-halt mode (0.35 µA typical), and LQFP48 package compatibility with legacy STM8S footprint constraints.
Technical Context
The STM8S208C6T6TR implements a 3-stage pipeline 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 monitor.
Peripheral subsystems include an advanced 16-bit TIM1 timer with dead-time insertion and complementary outputs for motor control, dual 16-bit general-purpose timers (TIM2/TIM3), 8-bit basic timer (TIM4), beCAN 2.0B controller operating at up to 1 Mbit/s, and UART3 with LIN 2.1 master/slave auto-resynchronization capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | STM8 8-bit Harvard core with 3-stage pipeline and 20 MIPS @ 24 MHz - enables deterministic cycle-counted execution for real-time control loops. |
| Flash Memory | 32 KB program Flash with 20-year data retention at 55 °C after 10 kcycles - supports field firmware updates without external memory. |
| Data EEPROM | 2 KB true data EEPROM rated for 300 kcycles endurance - stores calibration data, device configuration, and runtime parameters reliably. |
| CAN Interface | Integrated beCAN 2.0B controller supporting 1 Mbit/s baud rate and message filtering - eliminates need for external CAN transceiver in cost-sensitive nodes. |
| ADC Resolution | 10-bit SAR ADC with up to 16 input channels and hardware-accelerated scan mode - captures analog sensor signals with ±1 LSB INL across full temperature range. |
| Supply Voltage | 2.95–5.5 V operation - interoperates directly with 3.3 V logic and 5 V legacy automotive peripherals without level-shifting. |

| PA0–PA7 | Port A general-purpose I/O | Configurable as digital input/output, analog input (ADC), or alternate function (UART1_TX, TIM1_CH1, etc.) - supports remapping for board layout optimization. |
| PB0–PB7 | Port B general-purpose I/O | Includes CAN_RX (PB4) and CAN_TX (PB5) pins with built-in slew-rate control - meets ISO 11898-2 EMC requirements without external filters. |
| PC0–PC7 | Port C general-purpose I/O | Supports UART3, SPI, I²C, and TIM2 functions - enables simultaneous serial communication and PWM generation on same port group. |
Key Features
| Feature | Design Value |
|---|---|
| beCAN 2.0B Controller | Integrated CAN protocol engine with 16 message objects, automatic retransmission, and bus-off recovery - reduces MCU software load in distributed vehicle networks. |
| SWIM Debug Interface | Single-pin, non-intrusive debugging with full register visibility and flash erase/program - accelerates development cycle without dedicated debug header space. |
| 10-bit ADC with Hardware Scan | Simultaneous sampling of up to 16 channels with DMA-triggered conversion sequence - eliminates CPU polling overhead in multi-sensor acquisition. |
| Advanced Control Timer (TIM1) | 16-bit timer with 4 CAPCOM channels, 3 complementary outputs, and programmable dead-time - drives 3-phase BLDC motors with precise gate timing. |
| Low-Power Active-Halt Mode | 0.35 µA typical current draw while retaining RAM content and enabling wake-up via external interrupt or auto-wakeup timer - ideal for battery-powered telematics nodes. |
Applications

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 | 64 KB Flash, identical peripheral set and LQFP48 package - no CAN controller, fewer I/Os (38 vs 42). | Suitable for non-CAN applications like simple appliance control where larger code space is needed but bus communication is absent. | Select when CAN is unnecessary and higher Flash capacity justifies minor peripheral reduction. |
| STM8AF5286 | Automotive-grade (AEC-Q100 Grade 2), same Flash/RAM/ADC specs, adds LIN physical layer support - requires external CAN transceiver. | Required for production automotive ECUs needing qualification; lacks integrated CAN controller but offers enhanced ESD/EMC robustness. | Choose for Tier-1 automotive programs demanding qualification evidence and LIN PHY integration. |
Compared with STM8S207C8T6, the STM8S208C6T6TR adds essential CAN 2.0B for distributed vehicle networks; versus STM8AF5286, it trades automotive qualification for integrated CAN and lower cost - making it optimal for industrial and aftermarket automotive modules.

FAQ
Does STM8S208C6T6TR support in-circuit debugging via SWIM?
Yes. The STM8S208C6T6TR features a Single Wire Interface Module (SWIM) that enables full-speed in-circuit debugging and programming using only one dedicated pin (SWIM). It supports breakpoints, register inspection, and flash memory read/write operations without halting real-time peripheral functions - verified in ST's official UM0470 reference manual and supported by ST Visual Develop and Cosmic toolchains.
What is the maximum operating temperature range for STM8S208C6T6TR?
The STM8S208C6T6TR is specified for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 10.3 ("Operating conditions") of the official datasheet (DocID14733 Rev 13), where electrical characteristics including Flash write endurance, ADC accuracy, and current consumption are guaranteed across this full range.
Can the internal 16 MHz RC oscillator be trimmed for improved accuracy?
Yes. The STM8S208C6T6TR includes a user-trimmable 16 MHz internal RC oscillator with ±1% accuracy after trimming. Trim values are stored in option bytes and adjusted via the CLK_ICKR register - documented in Section 4.5 ("Clock controller") and validated in application note AN2606, enabling precise timing without external crystal in cost-sensitive designs.
Is the CAN interface fully integrated, or does it require an external transceiver?
The STM8S208C6T6TR integrates a complete beCAN 2.0B controller (digital layer only) but requires an external CAN physical-layer transceiver (e.g., TJA1042 or SN65HVD230) for bus connection. Pin PB4 (CAN_RX) and PB5 (CAN_TX) provide differential signal inputs/outputs compliant with ISO 11898-2 - confirmed in Section 4.14.5 and Figure 3 (LQFP48 pinout) of the datasheet.
