The 16 KB Flash is field-reprogrammable; the 512-byte EEPROM is separate from Flash. Peripherals include I2C, LINbus, SPI, and UART/USART — the LIN interface is the typical choice for automotive body networks. The 7-channel 10-bit ADC handles analog inputs like temperature or position sensors. ## NRND status — what it means for procurement For a BOM line already qualified, the NRND flag isn't an immediate cut-off — but it does signal that a last-time-buy window or eventual EOL notice is on the horizon. For new designs, a pin-compatible alternative within the STM8A family should be evaluated. The NRND status applies to both tray and other packing options. ## 32-VFQFN package — layout and thermal notes The part comes in a 32-VFQFN exposed-pad package, supplier device package 32-VFQFPN 5x5 mm. Surface-mount only.","metaTitle":"STM8AF6246UCY STMicroelectronics 8-bit MCU, 16 MHz","metaDescription":"STM8AF6246UCY 8-bit automotive MCU, 16KB Flash, 2K RAM, 512B EEPROM, -40 to 125°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","Grade":"Automotive","Speed":"16MHz","Series":"STM8A","Package":"Tray","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","Qualification":"AEC-Q100","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 ~ 125°C (TA)","Supplier Device Package":"32-VFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4705","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/50583dbf408c178457ce0059a412707e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6246UCY/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6246UCY obsolete or NRND?","answer":"For new designs, a current-production STM8A variant should be selected."},{"question":"Is STM8AF6246UCY suitable for automotive applications?","answer":"Yes.
