512 Mbit SPI NOR Flash — code storage with Quad I/O throughput
The S25FL512SDPMFV010: It communicates over a SPI bus with Quad I/O support, allowing four data lines for read operations that can quadruple throughput compared to standard single-bit SPI.
66 MHz clock and Quad I/O — what it means for read bandwidth
The 66 MHz clock frequency is the base SPI rate. With Quad I/O enabled, the effective read throughput reaches 264 Mbps (66 MHz × 4 data lines) in fast-read mode, which is sufficient for shadowing code to RAM or executing in place (XIP) from the Flash at moderate core speeds.
Housed in a 16-SOIC package with 0.295-inch body width and 7.50 mm width, the part uses a standard wide-body SOIC footprint common to many SPI NOR Flash devices. The surface-mount package is suitable for reflow assembly and is compatible with automated pick-and-place lines.
