Dear supporters,


I have questions about read operation timing that described in the datasheet.

[Q1]In fig11.5 in the datasheet, should CE# and OE# be ramped up at the same time?
If case CE# and OE# cannot be started up at the same time, could you tell me a sequence and time that should be followed?

[Q2]The table 11.7.1 S29GL-P Read Operations in the datasheet, Is the tDF the time from the signal that come up later for either CE or OE?

Hi,

[A1] No it is. Both signals do not need to ramp up at the same time. For CE# going HIGH or OE# going HIGH first, there is no sequence defined. The host controller can do both.

 

[Q2] table 11.7.1 S29GL-P Read Operations in the datasheet, Is the tDF the time from the signal that comes up later for either CE or OE?
[A2] tDF is the time after the signal going HIGH first from CE# or OE#.

 

Thanks,
Ronak
