With Quad I/O, the effective data rate reaches about 33 MB/s in fast-read mode. This is adequate for most microcontroller code shadowing and FPGA configuration loads, but if your design needs faster boot or higher throughput, the FL-S series also offers 133 MHz variants such as the S25FL128SAGNFI011. The trade-off is a slightly higher cost and tighter timing margin on the PCB. ## Active lifecycle — no EOL risk for new designs The FL-S series is a mature, widely deployed family with long-term supply commitment from Infineon. ## Package and footprint — 8-WSON with exposed pad The pad is electrically connected to the die substrate, typically tied to ground. The small footprint (6 mm x 8 mm) saves board space compared to SOIC-8 alternatives. The part is surface-mount only.","metaTitle":"S25FL128SDPNFI001 NOR Flash, 128 Mbit, SPI Quad I/O, 66 MHz","metaDescription":"S25FL128SDPNFI001 from Infineon (Cypress) FL-S series: 128 Mbit SPI Quad I/O NOR Flash, 66 MHz clock, 2.7-3.6 V, -40 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":"Tube","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":"$3.0800","priceTiers":[{"qty":1,"price":"$4.49000","currency":"USD"},{"qty":10,"price":"$4.07100","currency":"USD"},{"qty":25,"price":"$3.98320","currency":"USD"},{"qty":50,"price":"$3.96160","currency":"USD"},{"qty":100,"price":"$3.55200","currency":"USD"},{"qty":250,"price":"$3.53908","currency":"USD"},{"qty":500,"price":"$3.40974","currency":"USD"},{"qty":1000,"price":"$3.24163","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S25FL128SDPNFI001/alternatives.json"},"ai":{"faq":[{"question":"Is S25FL128SDPNFI001 compatible with SPI Quad I/O?","answer":"Yes, the memory interface is SPI - Quad I/O, supporting standard SPI, Dual I/O, and Quad I/O read commands for higher throughput."},{"question":"What is the closest functional second-source for S25FL128SDPNFI001?","answer":"The S25FL128SAGNFI011 is a pin-compatible 128 Mbit NOR Flash in the same FL-S series with the same package and temperature grade, but it runs at 133 MHz instead of 66 MHz.
