First question asked First like given Welcome!

Hello,

We are using a S25FL128SAGNFI001 128Mbit flash memory and I notice that in our old design I am reviewing  that we directly connect the nWP and the nHOLD pins to Vcc=+3V3.

I understand from the datasheet that these pins are internally pulled high to Vcc.

My question is, would connecting them externally without any pull up to +3V3 cause any problem?

Thank you

Hi @Stas 

Please see our application note on layout guide at this link. Page 3 of the document recommends the use of suitable resistor, e.g., 4.7 k Ohm to10 k Ohm.

Hope this answers your question.

Regards.
