I would like to know the internal pull-up resistor on RESET# and WP# for the S25FS512S and S70FS01GS (1.8V) family.

Previous your answer of KBA218745, I know it was made "pull-up leakage "  circuit for FL-S (3V) family.

Is it same for the internal circuit of FS-S family?

If yes,

What is the leakage current in the pull-up leakage circuit of S25FS512S and S70FS01GS (1.8v) family?

Thank you & Regards,

Hello Masaya,

In addition to my previous response, the input leakage current is ~2uA, (-40C to 85C), as detailed on page 24

within the S25FS512S datasheet.  Therefore the internal "pull-up circuitry" is ~1Mohm.

Thank you and regards,

Albert

Hello  Masaya,

Yes, the "pull-up leaker" circuit also exists within the S25FS512S.  However, in order to calculate the approximate

pull-up circuit resistance specifically for the S25FS512S, please do keep in mind that the maximum VCC is 2.0V.

Thank you and regards,

Albert
