For new BOM lines or a design respin, a pin-compatible alternative within the STM8A family should be evaluated. For existing production, secure your last-time-buy quantities through independent distribution while the part remains available — we can quote and source to order against an RFQ, confirming current availability and pricing at quote time. ## AEC-Q100 and the 150°C operating ceiling The 150°C upper limit exceeds the typical 125°C automotive grade, enabling deployment in engine-bay, exhaust-adjacent, or brake-system zones where ambient heat is extreme. ## Interface mix and memory for body-electronics firmware The connectivity set — I²C, LINbus, SPI, and UART/USART — covers the standard automotive sub-system buses. LIN is the de facto protocol for door modules, seat controllers, and HVAC flap actuators; I²C and SPI handle local sensor and memory expansion. The 64 KB Flash and 2 KB EEPROM provide separate storage for program code and calibration/configuration data, which avoids wearing out the Flash with frequent parameter writes. The 6 KB RAM is adequate for moderate data buffering in LIN gateway or sensor-fusion roles, but a design with heavy CAN message queuing or large lookup tables will need to budget the RAM carefully.","metaTitle":"STM8AF6286UDY 8-bit MCU, 64KB Flash, 24MHz, AEC-Q100, NRND","metaDescription":"STMicroelectronics STM8AF6286UDY automotive 8-bit MCU: 64KB Flash, 6K RAM, 2K EEPROM, 24MHz, 25 I/O, LIN/I²C/SPI, -40 to 150°C, AEC-Q100.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"24MHz","Series":"Automotive, AEC-Q100, STM8A","Package":"Tray","RAM Size":"6K x 8","Core Size":"8-Bit","EEPROM Size":"2K 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","Core Processor":"STM8A","Package / Case":"32-VFQFN Exposed Pad","Product Status":"Not For New Designs","Data Converters":"A/D 7x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 150°C (TA)","Supplier Device Package":"32-VFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4468","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8f2b7fc85b40fcccfb0e2f211eabb8e1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6286UDY/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6286UDY AEC-Q100 qualified?","answer":"Yes, the STM8AF6286UDY is part of the Automotive, AEC-Q100 qualified STM8A series.
