Key Features
- 32KB Flash and 1KB integrated EEPROM at 24 MHz clock with 52 I/O lines in a LQFP-64 package, providing ample code storage and GPIO for complex control applications
- On-chip CAN 2.0B controller plus SPI, I2C, and 3 UART interfaces enabling multi-protocol communication without external interface ICs
- 10-bit ADC with up to 16 channels and hardware boundary scan (JTAG) support for in-system debugging and production test of sensor-intensive applications
Applications
The STM8S208R6T6 is well-suited for home appliance control, industrial motor drives, and building automation systems that require a cost-effective 8-bit MCU with integrated CAN connectivity and a rich peripheral set in a compact LQFP-64 footprint. Its 24 MHz CPU delivers sufficient processing throughput for real-time control loops, sensor data acquisition via the 10-bit ADC, and multi-node CAN bus communication. The integrated 1KB EEPROM also simplifies design by eliminating external non-volatile memory for configuration storage in appliances and HVAC controllers.

Frequently Asked Questions
What are the Flash, RAM, and clock speed specifications of the STM8S208R6T6?
The STM8S208R6T6 provides 32KB of Flash program memory, 2KB of RAM, and 1KB of integrated EEPROM, operating at a maximum CPU clock frequency of 24 MHz. These resources support moderately complex 8-bit firmware for control, communication, and measurement tasks without requiring external memory components.
Which communication interfaces are integrated in the STM8S208R6T6, and how do they simplify multi-node system designs?
The STM8S208R6T6 integrates a CAN 2.0B controller, SPI, I2C, and 3 independent UART interfaces, allowing the MCU to communicate simultaneously with CAN bus nodes, SPI sensors, I2C peripherals, and 3 serial devices without any external bridge ICs. This reduces BOM cost and board space in multi-node industrial and automotive applications compared to MCUs that require external CAN transceivers or UART expanders.
For a home appliance control design operating from 3 V to 5.5 V, how does STM8S208R6T6 in LQFP-64 compare to an STM8S105 in LQFP-32?
The STM8S208R6T6 in LQFP-64 provides 52 I/O lines and 32KB Flash versus the STM8S105's 32 I/O lines and 32KB Flash in a smaller LQFP-32 footprint. When the application requires CAN connectivity and more than 32 GPIO pins, the STM8S208R6T6 is the correct choice; for designs with fewer than 32 I/O requirements and no CAN bus, the STM8S105 offers a smaller and lower-cost package alternative.
Does the STM8S208R6T6 support in-circuit debugging, and what tools are compatible with its SWIM and JTAG interfaces?
Yes, the STM8S208R6T6 supports both SWIM (Single Wire Interface Module) for in-circuit debugging and programming and boundary scan via its JTAG interface. The SWIM interface is compatible with ST-LINK/V2 and ST-LINK/V3 debug probes available from STMicroelectronics and third-party suppliers, enabling breakpoint debugging, single-step execution, and firmware download through a single-wire connection at up to 24 MHz system clock.
