The Quad I/O interface uses four data lines for both address and data, so the effective throughput is roughly four times that of a single-bit SPI at the same clock rate. This matters when the design executes firmware directly from the Flash (XIP) or loads large lookup tables at boot. ## Package and footprint: 16-SOIC wide body","metaTitle":"S25FL128SAGMFVR03 128Mbit NOR Flash, 133 MHz Quad I/O","metaDescription":"Cypress S25FL128SAGMFVR03 128Mbit NOR Flash with 133 MHz Quad I/O SPI, 2.7V-3.6V, -40°C to 105°C, 16-SOIC.
