In practice, the controller overhead and command latency reduce that, but it still delivers fast code shadowing or XIP (eXecute-In-Place) performance for a 128 Mbit device. The QPI mode reduces the command overhead by using a single-wire command phase, which helps when the host controller supports it. If your design uses a single SPI (1-bit) interface, the part still works — you just leave the extra pins unconnected — but you lose the speed advantage. ## Package and thermal: 8-WSON with exposed pad That means no last-time-buy notice is in effect, and the part remains qualified for new designs. Infineon continues to manufacture the FL-L series, so the supply channel is stable through authorized and independent distributors.","metaTitle":"S25FL128LAGNFI011 128Mbit NOR Flash, SPI Quad I/O, 133 MHz","metaDescription":"Infineon/Cypress S25FL128LAGNFI011 128Mbit NOR Flash, SPI Quad I/O & QPI at 133 MHz, 2.7-3.6V, -40 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-L","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","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O, QPI","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 (5x6)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.8700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL128LAGNFI011","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL128LAGNFI011 when reusing this data.
