- “For a backward compatible SO16 footprint, the VIO supply is tied to VCC inside the package; thus, the IO will function at VCC level.” – I don’t see this statement in the latest FL256S datasheet (Rev. *P). Which revision datasheet are you using?
- The OPN you mentioned “S25FL256SAGMFI003” does not support VIO, thus it can only work at Vcc voltage range, i.e., 2.7V to 3.6V
- “S25FL256SAGMFIR03” is the recommended OPN , which has the same feature, package, and also VIO supported that can work at 1.8V.
your answer was so useful thank you.
