Dear Sir or Madam,
There is written the following in S25FL128S datasheet item 2.11: "For a backward compatible SO16 footprint, the VIO supply is tied to VCC inside the package; thus, the IO will function at VCC level."
Does it mean that VIO and VCC are shorted inside S25FL128SAGMFIR01 or not ?
Can I connect 2.5V to VIO and 3.3V to VCC of S25FL128SAGMFIR01 in my board or not ?
Thanks in advance for your clarification...
This note is for SO16 which do not have the VIO option.
The S25FL128SAGMFIR01 part you have has VIO (letter "R" in the OPN), so you can use VIO at 2.5V.
