This combination targets body-control modules, sensor nodes, and actuator drivers that must survive under-hood thermal profiles. ## NRND — plan a replacement now This means STMicroelectronics has flagged it for eventual discontinuation; new production programs should not select it. Buyers should evaluate the wider STM8A family or migrate to a newer automotive MCU series for long-term supply. ## 16 MHz core and memory — what fits The 16 MHz core speed is adequate for real-time control loops in automotive body electronics — LIN message handling, PWM generation for lamp or motor drivers, and sensor polling at sub-millisecond intervals. The 16 KB Flash and 2 KB RAM limit firmware to moderate-complexity applications; a LIN slave node with a few analog inputs and a PWM output fits comfortably. The 512-byte EEPROM is useful for calibration parameters and fault codes that must survive power cycles. ## AEC-Q100 and 150°C — the deployment envelope The 150°C maximum operating temperature places it in the Grade 0 tier, suitable for under-hood and engine-compartment environments where ambient temperatures exceed the 125°C limit of standard automotive parts.","metaTitle":"STM8AF6248TDY 8-bit MCU, 16 MHz, AEC-Q100, 48-LQFP","metaDescription":"STMicroelectronics STM8AF6248TDY automotive 8-bit MCU: 16 MHz core, 16 KB Flash, 2 KB RAM, 512 B EEPROM, AEC-Q100, -40 to 150°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"16MHz","Series":"Automotive, AEC-Q100, STM8A","Package":"Tray","RAM Size":"2K x 8","Core Size":"8-Bit","EEPROM Size":"512 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":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 150°C (TA)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2592","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/50583dbf408c178457ce0059a412707e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6248TDY/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6248TDY obsolete?","answer":"It is not yet discontinued, but STMicroelectronics has flagged it for phase-out.
