That is enough to support execute-in-place (XIP) from the Flash for many MCU and SoC designs, reducing the need for a separate RAM shadow. The 128 Mbit capacity (16 MB) holds a full firmware image plus configuration tables and a small file system. For designs that need more temperature headroom, the sibling S25FL128SAGMFV001 extends the operating range to 105°C. ## Supply rail and temperature compatibility If your application sees sustained junction temperatures above 85°C, the 105°C-rated variant (S25FL128SAGMFV001) is the better fit.","metaTitle":"S25FL128SAGMFIR11 128 Mbit NOR Flash, 133 MHz SPI, 16-SOIC","metaDescription":"S25FL128SAGMFIR11 from Infineon (Cypress) FL-S series: 128 Mbit NOR Flash, 133 MHz Quad-SPI, 2.7–3.6 V, -40 to 85 °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":"133 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":"16-SOIC","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.infineon.com/dgdl/Infineon-S25FL128S_S25FL256S_128_Mb_(16_MB)_256_Mb_(32_MB)_3.0V_SPI_Flash_Memory-DataSheet-v18_00-EN.pdf?fileId=8ac78c8c7d0d8da4017d0ecfb6a64a17","sourceUrl":null},"ai":{"faq":[{"question":"Does S25FL128SAGMFIR11 support 3.3 V operation?","answer":"Yes."},{"question":"What is the closest functional alternative to S25FL128SAGMFIR11?","answer":"If your design needs the wider temperature range, that variant is the direct upgrade."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL128SAGMFIR11","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL128SAGMFIR11 when reusing this data.
