The 80 MHz clock is the ceiling for Quad I/O reads. At that speed, the SPI bus delivers roughly 40 MB/s, which keeps a Cortex-M4 or M7 fed without waiting on flash wait states. The Quad I/O interface also means only six signal pins (CS, CLK, IO0–IO3) are needed, saving board area versus a parallel NOR. The 2.7 V minimum supply means the flash stays alive through a 3.3 V rail that dips during brownout or cold-crank. ## Package and footprint — 8-WSON with exposed pad The 8-pin footprint is shared with other FL-S density options, so a layout for the 128 Mbit part can also accept 256 Mbit or 512 Mbit siblings without a board spin.","metaTitle":"S25FL128SDSNFI003 128Mbit NOR Flash, 80 MHz Quad-SPI","metaDescription":"S25FL128SDSNFI003 is a 128Mbit SPI NOR Flash from Cypress FL-S series. 80 MHz Quad I/O, 2.7-3.6V, -40 to 85°C, 8-WSON.
