The QPI mode reduces command overhead by using the SPI bus for both address and data, which improves random-read efficiency. For a firmware-bringup engineer, the first-power checklist includes verifying the SPI mode (Mode 0 or Mode 3) matches the host controller and that the 1.7 V supply is within tolerance before enabling quad reads. For a BOM cost engineer, this avoids single-source risk flags and LTB surcharges.","metaTitle":"S25FS128SAGNFI003 128 Mbit SPI NOR Flash, 133 MHz, 1.7 V","metaDescription":"Cypress S25FS128SAGNFI003 128 Mbit SPI NOR Flash, 133 MHz Quad I/O, 1.7 V supply, -40°C to 85°C.
