AT25SF081 SPI Flash waveform timing verification
I am again looking at Figure 11-1 Read Manufacturer and Device ID Signal for the Flash device in the title.
I have created this diagram to describe my plan for implementing this operation:
As can be seen in the diagram, my FPGA will provide the system with a 12MHz clock.
On the SI side:
- tCLKL >
5ns
- tCLKH >
5ns
- tCSLS >
5ns
- tDS >
2ns
- tDH >
2ns
Should be satisfied as essentially all of the values CLKL, CLKH, CSLS, DSDH in my diagram above evaluate to around 42ns
.
On the SO side:
Should be satisfied, as I am trying to initiate a sample from the SO line exactly at a falling edge.
I.e. V = 0ns
, DIS = 0ns
Have I made a mistake here?
