It uses a SPI interface with Quad I/O and QPI support, clocked at 133 MHz. ## Supply rail and temperature — what fits Operating temperature spans -40°C to 85°C (TA), the industrial range. That covers outdoor telecom cabinets, factory-floor controllers, and automotive cabin-zone modules, but not under-hood or engine-bay environments. The supply is 1.7 V to 2.0 V — a 1.8 V ±10% rail is the natural home. If your board already runs a 3.3 V SPI bus, you'll need a level shifter or a different part from the FL-S series (which runs at 2.7 V to 3.6 V). ## Package and mounting Housed in an 8-WDFN exposed-pad package, supplier device package 8-WSON (5x6 mm). Surface-mount only. ## Lifecycle and sourcing Listed as Active on the lifecycle record — no end-of-life notice, no last-time-buy window. ROHS3 compliant per. No official second source is recorded in the ledger, but the FL-S series sibling S25FL128SAGNFI011 is a pin-compatible 128 Mbit part that runs on a 2.7 V to 3.6 V supply — a drop-in if you can tolerate the higher voltage rail.","metaTitle":"S25FS128SAGNFI101 NOR Flash, 128 Mbit, SPI Quad I/O, 133 MHz","metaDescription":"Cypress S25FS128SAGNFI101 128 Mbit NOR Flash, SPI Quad I/O at 133 MHz, 1.7 V–2.0 V supply, -40°C to 85°C, 8-WSON.","metaKeywords":null},"attributes":{"series":"FS-S","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Series":"FS-S","Package":"Tube","Technology":"FLASH - NOR","Memory Size":"128Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"8-WDFN Exposed Pad","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O, QPI","Voltage - Supply":"1.7V ~ 2V","Memory Organization":"16M x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-WSON (5x6)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.08","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.08000","currency":"USD"},{"qty":10,"price":"$3.70100","currency":"USD"},{"qty":25,"price":"$3.62080","currency":"USD"},{"qty":50,"price":"$3.60140","currency":"USD"},{"qty":100,"price":"$3.22910","currency":"USD"},{"qty":250,"price":"$3.21732","currency":"USD"},{"qty":500,"price":"$3.09978","currency":"USD"},{"qty":1000,"price":"$2.94694","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d3dacfaf83e491952e2cb1c0f4a64c8b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is S25FS128SAGNFI101 obsolete or end-of-life?","answer":"No. The lifecycle record shows an Active status with no end-of-life notice.
