It communicates over a standard SPI bus with Quad I/O support, pushing the read clock to 133 MHz — which translates to roughly 66 MB/s theoretical throughput in quad-output mode, enough to feed a Cortex-M or entry-level application processor without stalling the instruction bus. ## Quad I/O at 133 MHz — why the interface speed matters Quad-SPI is the main event here. A standard SPI bus at 133 MHz delivers 133 Mbps; with four data lines active in quad-output mode, the same clock yields 532 Mbps raw. For a 256 Mbit part that means a full-chip read in under half a second — relevant for fast boot times and OTA update windows. The FL-S series also supports continuous read (XIP) so the MCU can execute code directly from the Flash without copying to RAM first, as long as the memory controller handles the quad-address wraparound. ## Package and footprint — 16-SOIC wide body Housed in a 16-SOIC wide-body package (0.295-inch body width, 7.50 mm), the part is a surface-mount device that reflows on standard lead-free profiles. The 16-SOIC footprint is common across the FL-S family, so a board laid out for one density option can often take a drop-in replacement at a different capacity — useful for mid-life capacity upgrades without a PCB spin.","metaTitle":"Infineon S25FL256SAGMFIG00 256Mbit NOR Flash","metaDescription":"Infineon S25FL256SAGMFIG00 FL-S series 256Mbit NOR Flash, SPI/Quad I/O interface, 133 MHz clock, 16-SOIC, -40 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":"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)","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":"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":"$3.7567","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 S25FL256SAGMFIG00 support quad SPI?","answer":"Yes, the memory interface is SPI with Quad I/O support.
