For an existing production BOM, securing enough lifetime-buy stock through the independent channel is the practical path. ## Memory complement: embedded EEPROM saves a separate part The 2 KB EEPROM on the STM8AF62A8TDY is a genuine differentiator for automotive body electronics. Calibration tables, VIN fragments, fault counters, and trim values live in EEPROM without an external serial memory chip — saving a footprint and one supply rail. The 128 KB Flash holds mid-complexity firmware for a LIN node or a local actuator controller; 6 KB RAM handles a modest stack and a few frame buffers. The 24 MHz clock is the upper speed bin in the STM8A family, so timing margin for 20 kbaud LIN messages and PWM generation at a few kilohertz is comfortable. The 39 I/O are spread around all four sides, so a fan-out via pattern under the body is not required — the outer-row traces escape directly. No exposed thermal pad, so junction-to-ambient thermal management relies on copper pour and airflow rather than a pad via stitch. ## Sourcing posture — quoted to order","metaTitle":"STM8AF62A8TDY 8-bit MCU, 128KB Flash, AEC-Q100, 24 MHz","metaDescription":"STMicroelectronics STM8AF62A8TDY automotive 8-bit MCU. 128KB Flash, 6KB RAM, 2KB EEPROM, 24 MHz, -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":"39","Core Processor":"STM8A","Package / Case":"48-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 10x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~150°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.8100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a76a247b2d898b9b81fdf0b841467bbd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF62A8TDY/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF62A8TDY obsolete or NRND?","answer":"It is not yet marked obsolete, but ST has signalled it will not support new designs with this part.
