That clock rate, combined with the Quad I/O mode, delivers a sustained read throughput that keeps a Cortex-M or RISC-V core fed for execute-in-place (XIP) code shadowing without wait-state bottlenecks. ## Quad I/O read performance – what the 133 MHz clock buys At 133 MHz in Quad I/O mode, the S25FL256SAGBHIB03 can deliver around 66 MB/s sustained read throughput (133 MHz × 4 bits per cycle). That is enough to support real-time audio buffers, display frame buffers, or OTA staging without external DRAM. The SPI bus also keeps pin count low — only six signals (CLK, CS, IO0–IO3) — which simplifies layout on dense PCBs. The FL-S series has broad second-source overlap with other Quad-SPI NOR parts, but the active status means you are not forced to exercise that option yet. ## 24-BGA footprint – layout notes Housed in a 24-ball BGA measuring 6 mm x 8 mm (ball pitch 0.8 mm), this package fits on a two-layer board if the escape routing uses via-in-pad or dogbone fanout. The 0.8 mm pitch is manageable with standard PCB fabrication tolerances. Decoupling: a 100 nF ceramic within 2 mm of each supply ball pair, plus a 4.7 µF bulk cap near the BGA cluster, keeps the supply clean during page-program bursts.","metaTitle":"S25FL256SAGBHIB03 256 Mbit NOR Flash, 133 MHz Quad-SPI","metaDescription":"Cypress S25FL256SAGBHIB03 256 Mbit NOR Flash, SPI - Quad I/O, 133 MHz clock, 2.7V-3.6V supply, -40°C to 85°C, 24-BGA.
