AM3517 Layout NAND Flash

Hi all,

does anybody know some links about Layout Guidlines of NAND Flash Memories?
Do I have to pay attention on length mismatch or impedance control (50 Ohm)?

Thanks!

Konrad

    Hi Konard,

     

    According to me - You don't need to pay much attention for NAND Flash signal routing as , it is not high speed interface. It is better if you can match 50 Ohm impedance but if it is not possible then you can route those signal with 5 or 6 mil trace - or whatever you are using in your design.  Regarding Length I would say if  Nand data and control signals are matched with +/-20% tolerance it is fine. In my design I used to route this signal with 50 OHM and doesn't bother about length match as most of the time it is in +/-20% tolerance.

     

    Thanks,
