The 32-LQFP package brings out 28 I/O lines, plus I²C, LINbus, SPI, and UART/USART connectivity for mixed-protocol bus designs. ## Memory and peripheral budget for control loops With 8 KB Flash and 1 KB RAM, firmware must be lean—typical for LIN slave nodes, window-lift controllers, or seat-position sensors. The 640-byte EEPROM supports parameter storage (calibration, trim, VIN lookup) without external memory. ## Supply range and temperature coverage Brown-out detect, POR, and watchdog peripherals are integrated for robust reset handling in noisy automotive environments.","metaTitle":"STM8AF6226TASSSY 8-bit MCU, AEC-Q100, 16 MHz, 8 KB Flash","metaDescription":"STMicroelectronics STM8AF6226TASSSY automotive 8-bit MCU, AEC-Q100 qualified, 16 MHz core, 8 KB Flash, 1 KB RAM, 640 B EEPROM, 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":"Automotive, AEC-Q100, STM8A","Package":"Tray","RAM Size":"1K x 8","Core Size":"8-Bit","EEPROM Size":"640 x 8","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"28","Core Processor":"STM8A","Package / Case":"32-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 7x10b SAR","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"8KB (8K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7872","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6226TASSSY/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6226TASSSY obsolete?","answer":"It is not fully discontinued, but ST advises against using it in new designs.
