It uses a Quad-SPI interface clocked at 133 MHz, organised as 32M x 8 bits. ## 133 MHz Quad-SPI — what it means for boot and code shadowing ## 8-WSON exposed pad — footprint and rework notes The FL-S series is a mature, widely used NOR flash family, and the 256 Mbit density is a common capacity point that tends to stay in production longer than the high-density or niche variants.","metaTitle":"S25FL256SAGNFI003 256 Mbit NOR Flash, 133 MHz Quad-SPI","metaDescription":"S25FL256SAGNFI003 256 Mbit FL-S NOR Flash, 133 MHz Quad-SPI, 2.7-3.6V, -40 to 85°C, 8-WSON.
