The STM8AF6286TAX is officially obsolete per STMicroelectronics. That means no further factory orders are accepted — no last-time-buy window, no new production. If you have this part on a current BOM, you are looking at surplus or broker channels for remaining inventory. The 32-LQFP footprint and the STM8A core architecture are shared across the STM8AF series, so a pin-compatible drop-in is the first place to check. ## 24 MHz and the memory envelope — sizing the firmware At 24 MHz this is a workhorse 8-bit core, not a speed demon. The 64 KB Flash and 6 KB RAM suit a single control loop with moderate data tables — think LIN-based actuator control, sensor aggregation, or a simple HMI panel. The 2 KB EEPROM is handy for storing calibration offsets or fault codes without wearing the Flash.","metaTitle":"ST STM8AF6286TAX 8-bit MCU, 24MHz, 64KB Flash, 32-LQFP","metaDescription":"STMicroelectronics STM8AF6286TAX 8-bit MCU, 24MHz core, 64KB Flash, 6KB RAM, 2KB EEPROM, -40 to 85°C, 32-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"24MHz","Series":"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":"Obsolete","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 ~ 85°C (TA)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a76a247b2d898b9b81fdf0b841467bbd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6286TAX/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STM8AF6286TAX?","answer":"However, pin-compatible STM8AF62xx variants with the same 32-LQFP package and similar memory maps are the natural cross-shop candidates.
