It communicates over a SPI - Quad I/O bus at up to 133 MHz, which in quad-output mode delivers roughly 66 MB/s sustained read throughput — enough to keep a Cortex-M7 or a mid-range FPGA configuration controller fed without wait-state bottlenecks. ## Package and footprint — 16-SOIC wide-body, Tape & Reel Housed in a 16-SOIC (0.295\", 7.50 mm width) surface-mount package, this part uses the industry-standard wide-body SOIC footprint common to 256 Mbit and 512 Mbit serial NORs.","metaTitle":"S25FL256SAGMFIR03 256Mbit NOR Flash, 133 MHz Quad SPI","metaDescription":"S25FL256SAGMFIR03 256Mbit NOR Flash from Infineon's FL-S series. 133 MHz Quad SPI, 2.7V-3.6V, -40°C to 85°C, 16-SOIC.
