The 8 ns access time is the initial latency before the first data word appears — fine for boot and cache-line fills, but the real bandwidth comes from the Quad I/O burst mode.
The 24-TBGA package (8x6 mm body) saves board area but demands X-ray inspection and a rework station — not a hand-solder part. Supply voltage is 2.7V to 3.6V, so it works on a 3.3V rail with margin for brownout.
The S25FL128SAGBHI400 is a later revision in the same FL-S family. Both are 128Mbit NOR Flash with Quad SPI in a 24-TBGA package. The BHI400 variant is the current active version; the BHI300 may be older stock. Verify pin compatibility and timing against your board's layout before substitution.
