The 640-byte EEPROM block stores calibration constants and fault codes that must survive power cycles. A 5-channel 10-bit ADC is included for reading analog sensors such as temperature, position, or current-sense resistors. ## NRND status — plan the BOM transition This means STMicroelectronics is phasing out the part; it remains available for existing production runs but is not intended for new projects. Buyers should secure last-time-buy quantities for active builds or evaluate a pin-compatible replacement within the STM8A family for future designs.","metaTitle":"STM8AF6223PAU 8-bit MCU, 16 MHz, AEC-Q100, 20-TSSOP","metaDescription":"STM8AF6223PAU automotive 8-bit MCU with 16 MHz core, 8 KB Flash, 1 KB RAM, 640 B EEPROM, I²C/LIN/SPI/UART, AEC-Q100, -40 to 85°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":"Tube","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":"16","Core Processor":"STM8A","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Not For New Designs","Data Converters":"A/D 5x10b","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)","Supplier Device Package":"20-TSSOP","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7bf7b21f4a1a887507e01c07ab726cf0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6223PAU/alternatives.json"},"ai":{"faq":[{"question":"Does STM8AF6223PAU have I²C, LIN, and SPI interfaces?","answer":"Yes — the STM8AF6223PAU includes I²C, LINbus, SPI, and UART/USART connectivity, making it suitable for automotive body networks and sensor communication."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8AF6223PAU","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8AF6223PAU when reusing this data.
