That keeps the host controller's SPI peripheral from being the bottleneck in most embedded designs. The 66 MHz rating is the maximum clock; layout needs to keep trace lengths short and matched, especially if the SPI bus also drives a second device. The 256 Mbit density gives room for a bootloader, application image, and a small filesystem for configuration data. The FL-L series has broad distribution support, so supply continuity looks solid for the next several years. ## Package and mounting — 16-SOIC wide body","metaTitle":"S25FL256LDPMFI003 256Mbit NOR Flash, SPI Quad I/O, 66 MHz","metaDescription":"Cypress S25FL256LDPMFI003 256Mbit NOR Flash, SPI Quad I/O interface, 66 MHz clock, 2.7V-3.6V, -40°C to 85°C, 16-SOIC.
