The SPI interface keeps pin count to six or eight signals versus the 40+ needed for a parallel NOR. Cypress lists the S25FL128SAGMFB001 as Active. For dual-sourcing resilience, the FL-S family includes multiple density and package variants that share the same SPI command set, so a firmware port across siblings is straightforward. If you need a reel or tube quantity, the package code (MFB001) identifies the tube variant; the tape-and-reel suffix differs, so confirm the packing format when you request a quote.","metaTitle":"S25FL128SAGMFB001 128 Mbit NOR Flash, 133 MHz Quad SPI","metaDescription":"Cypress S25FL128SAGMFB001 128 Mbit SPI NOR Flash in 16-SOIC. 133 MHz Quad I/O, 2.7-3.6 V supply, -40 to 105°C.","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":"128Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","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":"S25FL128","Memory Organization":"16M x 8","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"16-SOIC","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.7549","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5eba24dbf0c8192a229847180607e238.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How does S25FL128SAGMFB001 compare to S25FL128SAGMFI001?","answer":"The S25FL128SAGMFB001 and S25FL128SAGMFI001 share the same 128 Mbit density, 133 MHz Quad-SPI interface, 2.7-3.6 V supply, and 16-SOIC package.
