It carries 128 KB of Flash program memory, 6 KB of RAM, and 2 KB of EEPROM — enough for moderate control firmware with field-update capability. The 52 general-purpose I/O lines and a 16-channel 10-bit ADC give it the peripheral count for sensor aggregation and actuator drive in a single chip. Supply voltage range is 2.95 V to 5.5 V. On-chip CAN and LIN interfaces make the STM8S208RBT3 a natural choice for automotive body modules — door controllers, seat adjusters, or HVAC blower nodes. The I²C, SPI, and UART ports handle sensor bridges and display panels. Brown-out detection and a watchdog timer are built in, so an external supervisor IC is optional for most applications. Package is 64-LQFP (10x10 mm), surface-mount only.","metaTitle":"ST STM8S208RBT3 8-bit MCU, 128KB Flash, 24MHz, -40 to 125°C","metaDescription":"STMicroelectronics STM8S208RBT3 8-bit MCU with 128KB Flash, 6KB RAM, 24MHz core, CAN/LIN, -40 to 125°C.
