EVK's schematics use 256MB or 512MB DDR3.

I want to know 2GB(512MB x 4) and 1GB DDR3s version schematics.

Please show me.

Best regards.

Hello,

  You may use the EVK scheme as base. Possible modifications are as following :

1) DRAM_ADDR15 may be added ;

2) CS1 channel (DRAM_SDCKE1, DRAM_CS1_B, DRAM_ZQ1) may be implemented

  for separate chip ;

3) Data bus DRAM_DATA[0-15] may be split between separate chips, assuming

  control and address signals are the same for all chips.

 

You may send us Your design for review ( using Community or request Support|NXP )

Have a great day,
Yuri
