Hi,

 

I have a board with a vr4131 processer and sdram K4S561632C-L75 with  CL=3, refresh period : 64ms (8K Cycle). how to calculate refresh interval to set the sdram control unit register, BCURFCNTREG by using the formula.

 

Refresh interval = BRF(13:0) × VTClock

 

 

 

If you have some idea, please help me

 

Thanks in advance

 

 

 

Regards,

 

Lucky
