W25/NX25 Serial Flash Memories
For your convenience, the table below includes NexFlash part numbers and their
corresponding Winbond part numbers. Winbond will continue to support ordering
of the existing NexFlash part numbers beginning with the "NX" prefix.
However, we recommend that you
use the new "W" part numbers for all new projects.
