T4240 256MB x16 NOR

Hi,

 

We need to connect 256MB x16 NOR Flash to T4240 IFC.

IC - S70GL02GS

 

Here is my configuration

ADM MODE 0, CSOR0[ADM_SHFT]=4

 

IFC_A[20:30]    ->    A[10:0] 

IFC_AD[0:15]  -> latch -> A[26:11]

IFC_AD[0:15]    <->    DQ[15:0]

 

Is it OK?

 

Flash VIO = 1.8V

Flash VCC = 3.3V    

 

 

We have four S70GL02GS devices on IFC.

Do we need a buffer on IFC_AD[0:15]?

 

 

Regards,

Suresh
