With 25 I/O lines and peripherals including I²C, LINbus, SPI, and UART/USART, plus a 7-channel 10-bit ADC, this part handles mixed-signal control loops and serial bus bridging in a single 32-VFQFPN package. That means it's still available for existing production but should not be selected for a new BOM. The STM8A family has pin-compatible higher-density and later-revision siblings; an ST FAE can point to the current recommendation for a new project. For a production line already qualified on this part, the NRND status doesn't trigger an immediate EOL — but it signals that ST is winding down the variant. Keep an eye on PCNs and plan a migration window. ## Package and footprint — what the layout engineer sees","metaTitle":"STM8AF6246UDX 8-bit MCU, 16 MHz, AEC-Q100, NRND","metaDescription":"STMicroelectronics STM8AF6246UDX automotive 8-bit MCU: 16 MHz core, 16 KB Flash, 2 KB RAM, -40°C to 150°C, AEC-Q100.","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":"Tape & Reel (TR)","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":"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":"16KB (16K 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":"$1.9182","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/50583dbf408c178457ce0059a412707e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6246UDX/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6246UDX obsolete?","answer":"It is not fully obsolete — it remains available for existing production — but it should not be selected for new BOMs. We can source it for ongoing manufacturing needs."},{"question":"What is the replacement for STM8AF6246UDX?","answer":"ST does not list a single direct replacement order code in the public record for this NRND part.
