That matters when your MCU or SoC boots from external flash: a 256 Mbit image loads in under a second, compared to several seconds over a standard SPI link. The Quad I/O interface uses four I/O pins for data, so check that your host controller has a Quad SPI peripheral — many Cortex-M and RISC-V parts do. The 80 MHz clock also means the PCB trace length and signal integrity matter; keep the SPI lines short and avoid vias if possible. No need to stockpile a last-time-buy yet — but as always, keep an eye on PCNs from Infineon.","metaTitle":"Infineon S25FL256SDSMFBG01 NOR Flash, 256 Mbit, 80 MHz","metaDescription":"Infineon S25FL256SDSMFBG01 256 Mbit NOR Flash, 80 MHz SPI Quad I/O, 2.7V-3.6V, -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":{"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":"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","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.5755","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5eba24dbf0c8192a229847180607e238.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S25FL256SDSMFBG01/alternatives.json"},"ai":{"faq":[{"question":"Does S25FL256SDSMFBG01 support Quad SPI and DTR mode?","answer":"The S25FL256SDSMFBG01 supports SPI Quad I/O, which uses four I/O lines for data transfer.
