That is enough to feed an execute-in-place (XIP) firmware image from the flash without a shadow copy to RAM, provided the host controller supports Quad I/O. For designs still using standard SPI (single data line), the same 80 MHz clock yields 80 Mbps — a factor-of-four difference that matters when sizing the boot time budget. ## AEC-Q100 qualification and the 105°C ceiling The 105°C maximum operating temperature covers under-hood and cabin-mounted electronics in passenger vehicles, as well as industrial equipment with ambient temperatures up to 85°C plus self-heating. The 2.7 V minimum supply ensures compatibility with 3.3 V rails that may dip during cold crank or battery discharge events. For a production BOM, this removes the obsolescence risk that haunts older NOR Flash densities.","metaTitle":"S25FL256SDSMFBG10 Infineon 256Mbit NOR Flash, 80MHz Quad I/O","metaDescription":"Infineon S25FL256SDSMFBG10 SPI NOR Flash, 256Mbit, 80MHz Quad I/O, 2.7–3.6V, AEC-Q100, −40°C to 105°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"S25FL256SDSMFBG10","Series":"Automotive, AEC-Q100, FL-S","Package":"Tray","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)","Clock Frequency":"80 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 ~ 105°C (TA)","Supplier Device Package":"16-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.1353","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is S25FL256SDSMFBG10 pin compatible with S25FL256SAGMFI000?","answer":"Yes, both parts share the same 16-SOIC footprint and are pin-compatible within the S25FL256 family."},{"question":"Does S25FL256SDSMFBG10 support 80 MHz SPI operation?","answer":"Yes, the device is rated for an 80 MHz clock frequency in Quad I/O SPI mode.
