Clocked at 66 MHz, the Quad I/O mode delivers a practical read bandwidth around 33 MB/s — enough for fast boot code or firmware shadowing to RAM. The supply range of 2.7V to 3.6V lets it run on a 3.3V rail with margin for ripple.
Package and footprint — 24-ball BGA
The part comes in a 24-ball TBGA (8x6 mm body), surface-mount only. The BGA footprint saves board area compared to an SOIC-16, but needs a reflow profile and post-solder X-ray inspection to verify ball wetting. The 24-BGA (8x6) supplier device package is the same mechanical outline used across the FL-S family, so a layout that fits the S25FL512SAGBHI variant will also accept this part.
