Dear

Product / Family = CY8C4045AZI-S413

Datasheet URL
http://www.cypress.com/file/230631/download

I want to know the theoretical time of Flash AC Specifications roughly.

Question1:
About SID175 of Electrical Specifications:
The datasheet says, SID175 "Row erase time" Max is 16msec.
I think it is the worst value(have a lot of margin).
In fact, I think required time is more short.
Could you tell me the time of SID175 roughly?

Question2:
About SID176 of Electrical Specifications:
The datasheet says, SID176 "Row program time after erase" Max is 4msec.
I think it is the worst value(have a lot of margin).
In fact, I think required time is more short.
Could you tell me the time of SID176 roughly?

Hi Hiroki san,

The typical time may be around 5ms total(write and erase), but it will vary from device to device. The guarantee is it will be less than the max  spec specified. If you want to check the time for your device, you can toggle a pin and before and after row write command and get the approximate timing.

Best Regards,
VSRS
