66 MHz clock — what it means for your read bandwidth
At 66 MHz, Quad I/O mode uses four data lines simultaneously.
Active lifecycle — no obsolescence pressure
There is no last-time-buy or NRND flag. For a BOM freeze, this part does not introduce supply risk from discontinuation. The FL-S series has a broad density range, so if you later need a smaller or larger part, the same interface and package options exist within the family.
Because it is an active, non-obsolete part, lead times are generally manageable through the standard supply chain.
