The Infineon S25FL064LABBHN023 is a 64 Mbit FL-L series NOR Flash organized as 8M x 8 bits. It communicates over SPI Quad I/O and QPI at up to 108 MHz.
The package keeps board footprint small.
The lifecycle stage for S25FL064LABBHN023 is marked as end-of-life hot (EOL hot), meaning the manufacturer has announced discontinuation and a last-time-buy window is active or imminent. For a BOM line that depends on this exact density and package, the procurement path is a last-time-buy commitment or surplus channel sourcing.
Integration note
Quad I/O mode uses four data lines (IO0–IO3) plus clock and chip-select. The 108 MHz clock rate calls for controlled-impedance traces on the data lines at full speed.
