Part Number: SN74CB3T16212
We want to select parallel NOR flash connection (48 connections) between two processors at power ON time only.
Our NOR flash access time would be 90ns.
We are planning to use SN74CB3T16212 4 or 5 ICs in our application to cover 48 connections.
Is it support parallel NOR flash interface?
What is the maximum data rate supported?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Fan.Wang:
All signal will be on 1.8V IO standard bidirectional and I think SN74CB3T16212 support 1.8V IO as mentioned in the datasheet.
1. All are 1.8V NOR & CPU & FPGA.
2. Max Data rate would be per pin would be 20-25MHz? How much fastest data rate it support?
Connections are shown below:-
In reply to RAHUL SHARMA52:
Actually, in my system there is no 5V supply if I use SN74CBT16232 then I have to generate 5V.
Another thing lets see if I generate 5V also in my system.
Please confirm whether this IC requires clock input also for the selection or S0 & S1 inputs are sufficient because i dont want to use clock input.
What is the maximum data rate supported by this?
and second thing if I use five SN74CB3T16212 IC then what are the limitation except cost & board size?
