Communication interfaces cover I²C, SPI, UART/USART, IrDA, and LINbus, which means this part can talk to serial sensors, displays, and motor drives without an external protocol bridge. ## Lifecycle and sourcing The STM8S103F3M6 is listed as active in production. It is available through independent distribution and can be quoted to order against an RFQ.","metaTitle":"ST STM8S103F3M6 8-bit MCU, 16 MHz, 8 KB Flash, 20-SOIC","metaDescription":"STMicroelectronics STM8S103F3M6 8-bit MCU with 16 MHz core, 8 KB Flash, 1 KB RAM, 640 B EEPROM, 16 I/O, 5x10-bit ADC, wide supply 2.95-5.5 V, -40 to 85°C.
