    For S25FL128S, how long can I send the instructions after the power up?



      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 ?



      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
