256 Mbit NOR Flash for firmware and data logging
The Infineon S25FL256SAGMFV010 is a 256 Mbit FL-S series NOR Flash organized as 32M x 8 bits, using the SPI Quad I/O interface for read and program operations at up to 133 MHz clock frequency. This density suits firmware images, boot loaders, and data logs in embedded systems where the processor executes code directly from the Flash (XIP) or shadows it to RAM on startup.
Active lifecycle for production builds
The base product number S25FL256 covers the full FL-S family, so PCNs and datasheet revisions for this density apply across the series.
16-SOIC package and board integration
Housed in a 16-SOIC (0.295", 7.50 mm width) surface-mount package, the device occupies a standard footprint compatible with common SOIC-16 land patterns. The supplier device package is 16-SOIC, and the part ships in tray packaging. For PCB layout, the 16-SOIC package requires no exposed thermal pad; decoupling capacitance of 0.1 µF close to each supply pin is typical for the 133 MHz SPI bus.
Sourcing for volume and BOM qualification
The FL-S series is a single-source line from Infineon — no direct pin-compatible second source exists from another manufacturer. For BOM risk mitigation, qualifying the S25FL256SAGMFV010 alongside a functionally equivalent NOR Flash from a different vendor (same package, same SPI Quad I/O, similar timing) is recommended for high-volume builds.
