For a 256 Mbit part, this matters most during firmware shadowing from Flash to RAM at power-up and during over-the-air update windows where the bus is busy. The SPI interface keeps the pin count low — only six signals for the Quad I/O — which simplifies the PCB routing and frees GPIOs on the MCU. ## Active lifecycle and supply continuity The FL-S series is a mature, widely deployed NOR Flash family with a long market history, which supports multi-year supply planning. ## Package and footprint — 16-SOIC wide-body The surface-mount SOIC footprint is standard for reflow assembly and hand-solder rework, and the wide-body variant gives better clearance for routing under the package.","metaTitle":"S25FL256SDPMFIG11 256 Mbit SPI NOR Flash, 66 MHz","metaDescription":"Infineon S25FL256SDPMFIG11 256 Mbit SPI NOR Flash in 16-SOIC. 66 MHz clock, Quad I/O, 2.7V-3.6V, -40°C to 85°C.","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":"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","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL256","Memory Organization":"32M 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":"$3.9508","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum clock frequency of S25FL256SDPMFIG11?","answer":"The maximum clock frequency is 66 MHz.
