If you have an active BOM line using this MCU, now is the time to secure lifetime-buy quantities or evaluate a pin-compatible migration path within the STM8A family. ## 32-VFQFPN — footprint and rework notes The package is a 32-lead VFQFN with exposed pad, 5x5 mm body (supplier device package 32-VFQFPN).","metaTitle":"STM8AF6226UAY 8-bit MCU, 16 MHz, 8 KB Flash, AEC-Q100, NRND","metaDescription":"STMicroelectronics STM8AF6226UAY 8-bit automotive MCU, 16 MHz core, 8 KB Flash, 1 KB RAM, 640 B EEPROM, AEC-Q100, -40°C to 85°C, 32-VFQFPN.","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-VFQFN Exposed Pad","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)","Supplier Device Package":"32-VFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2896","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7bf7b21f4a1a887507e01c07ab726cf0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6226UAY/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AF6226UAY obsolete?","answer":"It is not fully discontinued, but ST is phasing it out — new designs should avoid it, and existing BOM lines should secure last-time-buy inventory or qualify a replacement."},{"question":"What is the best replacement or alternative for STM8AF6226UAY?","answer":"A migration within the STM8A family — same core, same AEC-Q100 qualification — is the logical path, but pin compatibility and peripheral set must be verified against the specific application requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8AF6226UAY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8AF6226UAY when reusing this data.
