256 Mbit SPI NOR flash in a 16-SOIC footprint
The S25FL256SDPMFV001 is a 256 Mbit SPI NOR flash from Infineon's FL-S series, organized as 32M x 8, in a 16-SOIC (0.295", 7.50 mm width) surface-mount package. It communicates over a SPI Quad I/O interface at clock frequencies up to 66 MHz, delivering read throughput that suits code-shadowing and data-logging in embedded systems.
Infineon lists this part as Active in its product lifecycle, meaning the manufacturer continues to produce and support it for new designs.
