    25FL064 CS# at powerup

      Hi,

       

      we did a little (big?) mistake in the conception around the serial flash:

      on the last serie of cards (hundreds) we forgot to put a pullup resistor on the CS# (ChipSelect#) signal coming from an FPGA.

      The Vcc of the Flash rises about 40 ms before the CS# rises, which is contrary to what the datasheet requires (they should rise together with CLK and Data In too)

       

       

       

      Still the cards seem to work fine, but i wonder if there is a risk of corruption or anything alike?

       

      Thanks for your help,

       

      best regards,

       

      Jeremy
