That means it remains available for existing production runs, but new projects should not select it. ## Automotive-grade 8-bit core with 24 MHz throughput The STM8AF6269TCX is an 8-bit MCU from ST's automotive STM8A family, qualified to AEC-Q100. The 24 MHz core speed is enough for real-time body-control loops — window lift, wiper control, seat adjustment — where deterministic interrupt response matters more than raw MIPS. The 52 I/O pins in a 64-LQFP package give enough headroom for multiplexed switch inputs and LED drive outputs without an external expander. The internal oscillator trims to within 1% accuracy across temperature, saving a crystal on cost-sensitive boards. ## 32 KB Flash, 6 KB RAM, 1 KB EEPROM — memory sizing for body electronics The 32 KB program Flash is adequate for a LIN-node application with a bootloader, calibration tables, and the main control loop. 6 KB RAM supports moderate data buffering for UART or SPI transactions. The 1 KB EEPROM emulated in Flash (or dedicated, depending on the variant) stores calibration constants and fault codes without external serial memory. ## Peripherals and connectivity for automotive networks On-chip LINbus and I²C cover the two most common automotive body-network protocols. The 16-channel 10-bit ADC reads analog sensors — throttle position, temperature, potentiometer feedback — without an external converter. Brown-out reset and POR are integrated, so the MCU starts reliably on a rising supply rail.","metaTitle":"STM8AF6269TCX 8-bit MCU, 24 MHz, AEC-Q100, 32 KB Flash","metaDescription":"STM8AF6269TCX automotive 8-bit MCU: 24 MHz core, 32 KB Flash, 6 KB RAM, 1 KB 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","Speed":"24MHz","Series":"Automotive, AEC-Q100, STM8A","Package":"Tape & Reel (TR)","RAM Size":"6K x 8","Core Size":"8-Bit","EEPROM Size":"1K x 8","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"52","Core Processor":"STM8A","Package / Case":"64-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1625","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a76a247b2d898b9b81fdf0b841467bbd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6269TCX/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6269TCX obsolete or NRND?","answer":"Yes, ST lists it as Not Recommended for New Design (NRND).
