The supplier device package is 16-SOIC, and mounting is surface-mount only. No exposed pad — thermal dissipation relies on the package body and PCB copper; for high-duty-cycle writes above 85°C ambient, a few thermal vias under the part help keep junction temperature within the 125°C limit.","metaTitle":"S25FL128SDSMFN001 128Mbit NOR Flash, SPI Quad I/O, 80 MHz","metaDescription":"Cypress S25FL128SDSMFN001 128Mbit NOR Flash, SPI Quad I/O interface at 80 MHz, 2.7V-3.6V, -40°C to 125°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~125°C(TA)","Supplier Device Package":"16-SOIC","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5119","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S25FL128SDSMFN001/alternatives.json"},"ai":{"faq":[{"question":"Is S25FL128SDSMFN001 obsolete or still active?","answer":"The part is listed as active by the manufacturer.

For a direct 128 Mbit replacement, parts from the Macronix MX25L or Winbond W25Q series in the same 16-SOIC package are functional equivalents — verify the status register and command set differences in the respective datasheets before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL128SDSMFN001","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL128SDSMFN001 when reusing this data.
