The 25 I/O lines in a 32-LQFP package give you room for a 7-channel 10-bit ADC, plus I²C, LINbus, SPI, and UART connectivity. That means it's still available for existing production runs, but the clock is ticking on last-time-buy windows. If you're qualifying a new BOM, this is not the part to commit to. The STM8A family has multiple density and package variants; a pin-compatible drop-in with more Flash or RAM would be the natural migration path. Check the STM8AF62xx or STM8AF52xx series for a like-for-like replacement with the same 32-LQFP footprint. For an existing design already using this MCU, the NRND status means you should secure a last-time-buy quantity for the remaining production run, or plan a firmware port to a newer STM8A or STM32G0 device before the supply dries up.","metaTitle":"STM8AF6246TASSSX STMicroelectronics 8-bit MCU, 16 MHz","metaDescription":"STMicroelectronics STM8AF6246TASSSX 8-bit MCU: 16 MHz core, 16 KB Flash, 2 KB RAM, 512 B EEPROM, 32-LQFP, -40°C to 85°C.","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":"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-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":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8272","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/50583dbf408c178457ce0059a412707e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6246TASSSX/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6246TASSSX suitable for new designs?","answer":"No. It is still available for existing production, but any new BOM should target a current STM8A or STM32G0 alternative."},{"question":"What is the replacement for STM8AF6246TASSSX?","answer":"ST has not published a specific successor order code for this NRND part.
