This is a fit for body electronics, sensor fusion nodes, and actuator control in passenger vehicles and commercial vehicles. For a production BOM already qualified on this MCU, the immediate concern is securing enough supply to cover the remaining build window — the part is not yet EOL, so last-time-buy windows have not been triggered. For any new design, the sensible move is to evaluate a current-production STM8A or STM8L alternative before committing the layout. No official successor part number has been published by ST at this time. ## AEC-Q100 and the 125°C ceiling The 125°C upper limit covers under-hood and engine-bay environments where the ambient temperature inside the ECU can exceed 105°C. The AEC-Q100 flow includes extended reliability testing — HTOL, ESD, latch-up, and temperature cycling — that a non-automotive part does not see. If the application is not automotive, a commercial STM8S part at a lower price tier would do the same job. But if the BOM requires an AEC-Q100 traceable component, this is the right class of device.","metaTitle":"STM8AF6288TCY 8-bit MCU, 24 MHz, 64 KB Flash, AEC-Q100, NRND","metaDescription":"STMicroelectronics STM8AF6288TCY 8-bit MCU, 24 MHz core, 64 KB Flash, 6K RAM, 2K EEPROM, AEC-Q100, -40°C to 125°C.","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":"38","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":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.4500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a76a247b2d898b9b81fdf0b841467bbd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6288TCY/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM8AF6288TCY and STM8AF6288?","answer":"The order codes differ by the package suffix — the 'TCY' variant is a 48-LQFP tray package.
