It carries 16 KB of Flash program memory, 2K x 8 of RAM, and 512 x 8 of EEPROM — enough for moderate embedded control firmware with calibration or configuration data stored on-chip. That means ST still manufactures it for existing production, but they are not targeting it for new socket wins. For a new design, the safer call is to pick a current STM8A variant with compatible memory and pinout. The 7-channel 10-bit ADC handles analog inputs like temperature or position sensors without an external converter. Housed in a 32-LQFP (7x7 mm) with 25 I/O lines, this is a surface-mount package that reworks cleanly with hot air if the pad layout follows the recommended footprint.","metaTitle":"STM8AF6246TASSSY 8-bit MCU, 16 MHz, 16 KB Flash, 32-LQFP","metaDescription":"STMicroelectronics STM8AF6246TASSSY 8-bit MCU: 16 MHz core, 16 KB Flash, 2K RAM, 512 B EEPROM, 3V-5.5V, -40°C to 85°C, 32-LQFP.","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":"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","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)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8077","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/50583dbf408c178457ce0059a412707e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6246TASSSY/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6246TASSSY obsolete or NRND?","answer":"It is still available for existing production runs, but ST does not recommend it for new designs.
