For a new design, this part is not the starting point. ## AEC-Q100 grade and the 125°C ceiling That 125°C upper limit is the junction temperature for under-hood and engine-bay deployments — think engine control modules, transmission controllers, and body-domain nodes that sit near the exhaust or the radiator. The 3V to 5.5V supply range means it can run directly off a nominal 5V automotive rail or a 3.3V regulated supply without an extra level shifter. ## 24 MHz core, 64 KB Flash, 6 KB RAM — what fits The 2 KB of EEPROM (2K x 8) is useful for storing calibration tables and fault codes without wearing the Flash. The 7-channel 10-bit ADC covers basic analog inputs — throttle position, temperature, pressure — without an external converter. The connectivity block covers I²C, LINbus, SPI, and UART/USART, which covers the common in-vehicle serial buses. The 25 I/O lines in the 32-LQFP package (7x7 mm body) leave enough headroom for a small keypad, a few LED indicators, and the bus transceiver interface.","metaTitle":"STM8AF6286TCX 8-bit MCU, 24 MHz, 64 KB Flash, AEC-Q100, NRND","metaDescription":"STM8AF6286TCX 8-bit automotive MCU, 24 MHz core, 64 KB Flash, 6 KB RAM, AEC-Q100 qualified, -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":"Tape & Reel (TR)","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-LQFP","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 ~ 125°C (TA)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5139","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a76a247b2d898b9b81fdf0b841467bbd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6286TCX/alternatives.json"},"ai":{"faq":[{"question":"What is the recommended replacement for the STM8AF6286TCX?","answer":"For a new design, evaluate the current STM8A or STM32A automotive MCU families from STMicroelectronics for a pin-compatible or functionally equivalent alternative.
