Value of Internal Pull-Up Resistor on RESET#, HOLD#, and WP# for the S25FL-S and S25FL-L Series - KBA218745

Question: 

Does the S25FL-S and S25FL-L family series have an internal pull-up resistor on RESET#, HOLD# and WP# pins? If yes, what is the value of the pull up resistor? 

Answer: 

Yes, there is a “pull-up” circuit on RESET#, HOLD# and WP# pins for the S25FL-S and S25FL-L Series, but it is not implemented as a single resistor so a resistance value cannot be quoted. Cypress design uses a “pull-up leaker” circuit, which is a chain of transistors with a peak ~2-µA leakage current during normal operation. Search the datasheet for “leakage current” to confirm this value.
