For new designs, ST's current STM8A or STM32A automotive families are the migration path — pin-compatible or software-portable options exist, but no single drop-in successor is listed on the official record.","metaTitle":"STM8AF5289TCX 8-bit MCU, 24 MHz, 64 KB Flash, AEC-Q100, NRND","metaDescription":"STMicroelectronics STM8AF5289TCX automotive 8-bit MCU: 24 MHz core, 64 KB Flash, 6 KB RAM, CAN/LIN/I2C/SPI, -40 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":"CANbus, I²C, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"52","Core Processor":"STM8A","Package / Case":"64-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 16x10b","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":"$3.5849","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a76a247b2d898b9b81fdf0b841467bbd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF5289TCX/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF5289TCX obsolete or end of life?","answer":"Existing production can still be supported, but the part is on a path toward end-of-life.
