At that clock rate, the Quad I/O mode delivers a sustained read throughput that keeps an MCU's execute-in-place (XIP) prefetch fed without wait-state penalties — a real consideration when the bus is shared with other SPI peripherals. ## Package and footprint — 8-WSON with exposed pad The device comes in an 8-WSON (6x8 mm) exposed-pad package. The FL-S series remains in volume production, and the base product number S25FL256 is a current catalog line. This means no last-time-buy scramble — the BOM line can be committed without obsolescence contingency.","metaTitle":"S25FL256SAGNFI011 256Mbit NOR Flash – SPI Quad I/O, 133 MHz","metaDescription":"Infineon FL-S series 256Mbit NOR Flash, SPI Quad I/O interface, 133 MHz clock, 2.7V-3.6V supply, -40°C to 85°C, 8-WSON (6x8mm) package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"FL-S","Package":"Tube","Technology":"FLASH - NOR","Memory Size":"256Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"8-WDFN Exposed Pad","Product Status":"Active","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL256","Memory Organization":"32M x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-WSON (6x8)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.3100","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S25FL256SAGNFI011/alternatives.json"},"ai":{"faq":[{"question":"Is S25FL256SAGNFI011 active or end-of-life?","answer":"It is Active — no EOL notice, no last-time-buy date.
