The 66 MHz clock is the rated maximum; the actual throughput depends on the MCU's QSPI controller and the command overhead. For designs that need higher burst rates, the FL-S family includes 104 MHz variants, but the 66 MHz part is the cost-optimized choice for industrial temperature ranges. The FL-S series has broad second-source coverage across the 128 Mbit density, so if a pin-compatible alternate is needed for dual-sourcing, the S25FL128SDPMFI003 (same die, different package) is a direct cross. ## 8-WSON package — footprint and thermal","metaTitle":"S25FL128SDPNFI003 128 Mbit NOR Flash, Quad-SPI, 66 MHz","metaDescription":"Cypress S25FL128SDPNFI003 128 Mbit NOR Flash, SPI - Quad I/O, 66 MHz clock, 2.7V-3.6V, -40°C to 85°C, 8-WSON.","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":"Tape & Reel (TR)","Technology":"FLASH - NOR","Memory Size":"128Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"8-WDFN Exposed Pad","Product Status":"Active","Clock Frequency":"66 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~85°C(TA)","Supplier Device Package":"8-WSON (6x8)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3950","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S25FL128SDPNFI003/alternatives.json"},"ai":{"faq":[{"question":"Does S25FL128SDPNFI003 support quad SPI?","answer":"Yes, the S25FL128SDPNFI003 supports SPI - Quad I/O, which reads four bits per clock cycle at up to 66 MHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL128SDPNFI003","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL128SDPNFI003 when reusing this data.
