The 25 I/O lines are enough for a typical LIN node with a few local sensors and a relay driver. It is a current-production part, safe for new-design qualification and available through independent distribution.","metaTitle":"STM8AF6266IUCY Automotive 8-Bit MCU, 16 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM8AF6266IUCY automotive-grade 8-bit MCU: 16 MHz core, 32 KB Flash, 2 KB RAM, 1 KB EEPROM, AEC-Q100 qualified, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Grade":"Automotive","Speed":"16MHz","Series":"STM8A","Package":"Tray","RAM Size":"2K x 8","Core Size":"8-Bit","EEPROM Size":"1K x 8","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I2C, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"25","Qualification":"AEC-Q100","Core Processor":"STM8A","Package / Case":"32-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 7x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/50583dbf408c178457ce0059a412707e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6266IUCY/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6266IUCY AEC-Q100 qualified?","answer":"Yes, the STM8AF6266IUCY carries AEC-Q100 qualification, making it suitable for automotive applications requiring the standard stress and reliability screening."},{"question":"Are there equivalents to STM8AF6266IUCY?","answer":"Within the STM8A family, pin-compatible variants differ by Flash and RAM density.
