Hello Cypress community,

I want to use S25FL256SAGMFI003 SOIC-16, with 1.8V procsessor. I had a doubt about 1.8V working because I faced with this sentence "For a backward compatible SO16 footprint, the VIO supply is tied to VCC inside the package; thus, the IO will function at VCC level." in datasheet could you please help me to clarify the right meaning of this sentence and whether can i use this package with 1.8V or not?

Sincerely yours,

Siyavash

Hello,

  1. 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?
  2. 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
  3. “S25FL256SAGMFIR03” is the recommended OPN , which has the same feature, package, and also VIO supported that can work at 1.8V.

Thank you

Regards,

Bushra
