For ongoing production, secure your volume requirements early; once the LTB window closes, the only channel will be independent distribution, where date-code provenance and pricing vary lot to lot. ## Memory and peripheral sizing 16 KB of Flash and 2 KB of RAM. A typical LIN slave node or window-lift controller fits; a full CANopen stack with multiple PDO mappings will likely overflow.","metaTitle":"ST STM8AF6246TCSSSX 8-bit MCU, 16 MHz, AEC-Q100, 32-LQFP","metaDescription":"STM8AF6246TCSSSX automotive 8-bit MCU with 16KB Flash, 2KB RAM, 16 MHz core, AEC-Q100 qualified, -40 to 125°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":"Automotive, AEC-Q100, STM8A","Package":"Tape & Reel (TR); Cut Tape (CT)","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~125°C(TA)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.7900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/50583dbf408c178457ce0059a412707e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6246TCSSSX/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6246TCSSSX obsolete or nearing end of life?","answer":"It is not yet fully obsolete, but STMicroelectronics has signaled that it will not support new designs with this part.
