The STM8AF6286UDX carries a Not Recommended for New Designs (NRND) status. That means ST is still manufacturing it for existing production, but the window for new design-ins is closing. If you are qualifying a fresh BOM, look at the current-production STM8A siblings in the same 32-VFQFPN footprint — ST typically keeps the peripheral set and pinout consistent across the series. For an active line already using this code, secure your last-time-buy quantities through independent distribution; we can quote and source to order against an RFQ. ## What the 150°C rating means for the assembly The -40°C to 150°C operating temperature range is the full automotive junction-temperature spec — not just cabin-grade 85°C. This part is rated for exhaust-adjacent or under-hood locations where ambient air can hit 125°C and self-heating pushes the die to 150°C. ## Peripheral set for LIN and local control The STM8AF6286UDX includes I²C, LINbus, SPI, and UART/USART connectivity — the LIN interface is what typically drives the choice for automotive sub-networks (door modules, seat controllers, HVAC flaps). Seven 10-bit ADC channels handle analog sensor reads, and the built-in PWM, brown-out reset, POR, and watchdog peripherals reduce external supervisor IC count. The 25 I/O lines in the 32-pin package leave room for local switch sensing and LED drive.","metaTitle":"STM8AF6286UDX 8-bit MCU, 24MHz, 64KB Flash, AEC-Q100","metaDescription":"STM8AF6286UDX automotive 8-bit MCU, 24MHz core, 64KB Flash, 6KB RAM, 2KB EEPROM, -40 to 150°C, 32-VFQFPN.","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-VFQFN Exposed Pad","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 ~ 150°C (TA)","Supplier Device Package":"32-VFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4468","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8f2b7fc85b40fcccfb0e2f211eabb8e1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6286UDX/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6286UDX obsolete or not for new designs?","answer":"ST continues to supply it for existing production, but new projects should target a current-production STM8A variant."},{"question":"What is the best replacement for STM8AF6286UDX?","answer":"ST does not publish a single direct successor for the NRND STM8AF6286UDX.
