Hi

I am using the flash chips of CYPRESS,S25FL128SAGNFI000, but I have a question that i don't understand..

Would you tell me after the flash chip powered up, how long can I send the instructions to the chip?

Is there some time should be waited ?

P.S.

at the chip simulation model, there is a massage , the chip will be powered up after 300us, but it is in the simulation model.

what about in the real board?

-- VCC (min) to CS# Low

tdevice_PU              : VitalDelayType := 300 us;  --tPU

Looking forward to your reply~thanks

Hi,

The flash device after a power up is ready by default for read operation, but there is this time interval tPU which is time from when Vcc min is applied to the device to the time when device is ready for a read operation. It is 300 us same as the value used in simulation model.
