Device Resetting Time
K9F2808U0B-Y
only
1. If tCS is set less than 10ns, tWP must be minimum 35ns, otherwise, tWP may be minimum 25ns.
NOTE :
NOTE :
1. If reset command(FFh) is written at Ready state, the device goes into Busy for maximum 5us.
2. To break the sequential read cycle, CE must be held high for longer time than tCEH.
3. The time to Ready depends on the value of the pull-up resistor tied R/B pin.
Parameter
Last RE High to Busy
(at sequential read)
CE High to Ready(in case of inter-
ception by CE at read)
CE High Hold Time(at the last
serial read)
Parameter
