It uses a Quad I/O SPI interface running at up to 108 MHz, giving read throughput that keeps up with code-shadowing and data-logging tasks in automotive and industrial controllers. AEC-Q100 qualification means it was screened for the reliability margins an automotive ECU or ADAS module expects. That means the manufacturer no longer accepts production orders; the only channel for this part is surplus inventory or broker stock. If you have an active design using this exact code, you need a last-time-buy plan or a validated replacement. The base product number S25FL164 suggests a family-level replacement path — check the S25FL164 series for a current-production variant that matches the 8-WSON footprint and Quad-SPI interface. ## What the 108 MHz Quad-SPI means for the design That is enough to support execute-in-place (XIP) for many MCUs without stalling the core on cache misses. The 3 ms page write time is typical for NOR — budget accordingly for firmware updates if the application writes more than a few pages per update cycle. The 8-WSON package (5x6 mm) with exposed pad helps thermal dissipation during sustained write operations, though the 64 Mbit density rarely pushes thermal limits in normal use.","metaTitle":"S25FL164K0XNFA010 NOR Flash, 64Mbit, SPI Quad I/O, 108 MHz","metaDescription":"Cypress S25FL164K0XNFA010 64Mbit NOR Flash, SPI Quad I/O, 108 MHz clock, AEC-Q100 automotive grade.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"Automotive, AEC-Q100, FL1-K","Package":"Tray","Technology":"FLASH - NOR","Memory Size":"64Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"8-WDFN Exposed Pad","Product Status":"Obsolete","Clock Frequency":"108 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL164","Memory Organization":"8M x 8","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-WSON (5x6)","Write Cycle Time - Word, Page":"3ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7d9913df32b66d1dec79117d154aa352.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for S25FL164K0XNFA010?","answer":"Cypress has not published a single direct successor order code for this exact variant.
