128 Mbit SPI NOR Flash with Quad I/O
The S25FL128SAGMFV000 is a 128 Mbit (16M x 8) NOR Flash memory from Infineon's FL-S series, using the SPI - Quad I/O interface. It clocks at 133 MHz, and with Quad I/O the effective read throughput can reach 532 MHz equivalent (4-bit wide), which matters for fast code shadowing or firmware execute-in-place (XIP) from the flash.
The 1.27 mm pitch is layout-friendly on a two-layer board — no micro-via fanout required. The supplier device package is also 16-SOIC, so the footprint is consistent across the FL-S series for this density. Supplied in a Tray — typical for prototype or low-volume builds. For high-volume reels, confirm the packing option with the order code suffix.
