At 66 MHz, the Quad I/O interface delivers about 33 MB/s in continuous read. That is enough to feed a Cortex-M or low-end application processor without stalling on instruction fetch, as long as the flash controller on the SoC supports Quad I/O and the layout keeps the SPI traces short. If the design needs faster throughput — for example, a higher-resolution display frame buffer or a faster CPU — the 133 MHz siblings in the FL-S family (S25FL128SAGMFV010, S25FL128SAGBHIA10) are worth a look, though they may trade off package or temperature range. ## Package and footprint — 8-WSON with exposed pad The part comes in an 8-WDFN Exposed Pad, supplier package designation 8-WSON (6x8 mm). ## Active lifecycle — no near-term end-of-life pressure For designs that need a second source, the FL-S family includes several 128 Mbit variants with the same base number (S25FL128) — the S25FL128SDSNFI000 (80 MHz, same package) and the S25FL128SAGMFV010 (133 MHz, -40 to 105°C, different package) — but none is a drop-in pin-compatible alternate without checking the footprint and temperature grade.","metaTitle":"S25FL128SDPNFI000 128 Mbit SPI NOR Flash, 66 MHz, Quad I/O","metaDescription":"S25FL128SDPNFI000 FL-S series 128 Mbit NOR Flash, SPI Quad I/O interface, 66 MHz clock, 2.7-3.6 V, -40°C to 85°C, 8-WSON.","metaKeywords":null},"attributes":{"series":"FL-S","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"FL-S","Package":"Tray","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":"$4.4900","priceTiers":[{"qty":1,"price":"$4.49000","currency":"USD"},{"qty":10,"price":"$4.07100","currency":"USD"},{"qty":25,"price":"$3.98320","currency":"USD"},{"qty":40,"price":"$3.96150","currency":"USD"},{"qty":80,"price":"$3.55200","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S25FL128SDPNFI000/alternatives.json"},"ai":{"faq":[{"question":"What is the memory size and interface of S25FL128SDPNFI000?","answer":"The S25FL128SDPNFI000 is a 128 Mbit NOR Flash, organised as 16M x 8 bits."},{"question":"What is the replacement or equivalent for S25FL128SDPNFI000?","answer":"There is no official replacement, since the part is still active. Within the same FL-S family, the S25FL128SDSNFI000 is a close functional equivalent — same 128 Mbit density, same 8-WSON package, but with an 80 MHz clock instead of 66 MHz. The S25FL128SAGMFV010 offers 133 MHz and an extended -40 to 105°C range but comes in a different package.
