The 16-SOIC is a common footprint for serial NOR Flash, so it usually drops onto an existing land pattern without a board spin.","metaTitle":"S25FL128SDSMFBG01 128Mbit NOR Flash, 80 MHz Quad-SPI","metaDescription":"Cypress S25FL128SDSMFBG01 128Mbit FLASH - NOR memory, 80 MHz SPI - Quad I/O, 2.7V-3.6V, -40°C to 105°C, 16-SOIC.","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":"80 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","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5eba24dbf0c8192a229847180607e238.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S25FL128SDSMFBG01/alternatives.json"},"ai":{"faq":[{"question":"What is the exact replacement for S25FL128SDSMFBG01 if it becomes obsolete?","answer":"If obsolescence is announced, the FL-S series includes other 128 Mbit Quad-SPI parts in the same 16-SOIC footprint, but a direct pin-compatible replacement would need to be confirmed from a future Cypress/Infineon cross-reference. For now, the active status means no replacement is required."},{"question":"Does S25FL128SDSMFBG01 require any specific programming algorithm or voltage?","answer":"No special programming voltage is needed — the same 3.3 V rail that powers the MCU also powers the Flash. The programming algorithm follows the standard NOR Flash command set for the FL-S family; any programmer that supports Cypress FL-S series Quad-SPI parts will handle it."},{"question":"Is S25FL128SDSMFBG01 a direct replacement for S25FL128SDSMFB001 in a 3.3V SPI design?","answer":"The suffix difference (MFBG01 vs MFB001) typically indicates a minor revision or packaging variant, but the electrical and footprint compatibility should be verified against the respective datasheets. In most 3.3 V SPI designs they are interchangeable."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL128SDSMFBG01","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL128SDSMFBG01 when reusing this data.
