At this speed, the MCU can execute most single-cycle instructions, giving it enough headroom for tasks like PWM generation at automotive-relevant frequencies, LINbus message handling, and 10-bit ADC conversions at 7 channels without stalling the control loop. The 32 KB Flash (32K x 8) holds the application firmware. For a typical automotive body-control function — door module, seat adjuster, or HVAC actuator — this is adequate for the main loop, interrupt handlers, and a modest bootloader. The 2K x 8 RAM supports a few hundred bytes of stack and global variables; the 1K x 8 EEPROM stores calibration constants and fault codes without needing external non-volatile memory. The EEPROM endurance is rated for the STM8A family's standard 100k write cycles, sufficient for wear-leveled parameter storage over a vehicle's lifetime. ## NRND — planning for the last-time buy This means STMicroelectronics will continue to manufacture the part for existing production programs, but new designs should target a replacement. Procurement teams should secure sufficient inventory through the LTB or qualify a pin-compatible second source within the STM8A family. ## Peripherals and connectivity for automotive networks The 25 I/O lines, brown-out detect/reset, POR, PWM, and watchdog timer (WDT) are standard for body-control applications. The 7-channel 10-bit ADC handles analog sensor inputs — temperature, position, or voltage monitoring — without an external converter.","metaTitle":"STM8AF6266ITCY 8-bit MCU, 16 MHz, 32 KB Flash, AEC-Q100","metaDescription":"STMicroelectronics STM8AF6266ITCY 8-bit MCU, 16 MHz core, 32 KB Flash, 2K x 8 RAM, AEC-Q100 qualified, -40°C 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":"Tray","RAM Size":"2K 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":"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":"32KB (32K 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":"$2.2258","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/50583dbf408c178457ce0059a412707e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6266ITCY/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STM8AF6266ITCY?","answer":"An official replacement part number is not listed in the available records.
