It runs at 16 MHz from an internal oscillator, with 8 KB of Flash program memory, 1K x 8 RAM, and 640 x 8 EEPROM — the EEPROM is useful for storing calibration constants and fault codes without external parts. The 150°C operating temperature rating places it in grade-0 territory, suitable for engine-bay or transmission control where standard 125°C parts won't survive. The 5x10-bit ADC handles sensor input from thermistors or potentiometers. ## NRND — plan the last-time buy or replacement now This means ST is winding down production; a last-time-buy window is in effect or imminent. New designs should target the successor or a pin-compatible alternative. For existing BOM lines, secure sufficient lifetime buy stock through independent distribution now — the window will close. The closest pin-compatible alternative within the STM8A family shares the same core, memory, and peripheral set but differs in packaging or temperature grade — verify the exact variant against your assembly and environmental requirements before substituting. ## 16 MHz core with LINbus — built for body and powertrain networks The 16 MHz clock drives the STM8A core with single-cycle instruction execution for many opcodes, delivering around 16 MIPS. That's enough for real-time control loops in wiper modules, HVAC actuators, seat controllers, or simple sensor fusion nodes. The LINbus interface connects directly to the vehicle's local interconnect network without an external transceiver — a BOM simplification for body-electronics modules. With 16 I/O lines in a 20-TSSOP package, board area is minimal. Brown-out detect and POR are integrated, so the reset circuit can be a simple RC network.","metaTitle":"STM8AF6223PDU 8-bit MCU, AEC-Q100, 16 MHz, 8 KB Flash, 150°C","metaDescription":"STM8AF6223PDU automotive 8-bit MCU, AEC-Q100 grade-0, 16 MHz core, 8 KB Flash, 640-byte EEPROM, LINbus, -40 to 150°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 ~ 150°C (TA)","Supplier Device Package":"20-TSSOP","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7bf7b21f4a1a887507e01c07ab726cf0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6223PDU/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6223PDU obsolete?","answer":"Production has not ceased, but the part is no longer recommended for new projects.
