Quad I/O at 66 MHz gives a theoretical read throughput near 33 MB/s, enough for execute-in-place (XIP) of boot code or small firmware kernels without shadowing to RAM. The QPI mode reduces the command overhead by operating the bus in a 4-bit-wide command cycle after the initial instruction, which helps when the host controller supports it. This makes it a safe choice for a production BOM that will run for several years. ## 16-SOIC footprint — board-level fit The wide body gives good clearance for routing the SPI bus lines under the part on a two-layer board. No exposed thermal pad — the 256 Mbit NOR Flash dissipates little power during reads, so thermal management is not a concern.","metaTitle":"S25FL256LDPMFN001 256Mbit NOR Flash, 66 MHz SPI","metaDescription":"Infineon S25FL256LDPMFN001 256Mbit NOR Flash memory, SPI Quad I/O interface at 66 MHz, 2.7-3.6V supply, -40 to 125°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-L","Package":"Tube","Technology":"FLASH - NOR","Memory Size":"256Mbit","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":"66 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O, QPI","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL256","Memory Organization":"32M x 8","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"16-SOIC","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.7500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fddab2140198b53f244f99aa103ac091.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is S25FL256LDPMFN001 compatible with standard SPI?","answer":"Yes, it supports standard SPI (single I/O) as well as Quad I/O and QPI modes. The device defaults to single SPI after power-up, so it works with any SPI master that can issue the standard Read command. Quad I/O and QPI are enabled by writing the appropriate configuration register bits."},{"question":"What is the equivalent or replacement for S25FL256LDPMFN001?","answer":"The S25FL256LDPMFN001 is an Infineon FL-L series part. Within the same series, density variants (128 Mbit, 512 Mbit) share the same 16-SOIC footprint and interface, so a pin-compatible density upgrade or downgrade is possible if the firmware image size allows."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL256LDPMFN001","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL256LDPMFN001 when reusing this data.
