MPC8358 DDR2 ECC Registered

[Amit24]

Hi we have used  MPC8358 in our design a 5 year ago. Now, we are facing a problem shortage of DDR2 SDRAM ECC registered buffered.So Anyone cal able to tell me, Can we replace or design a new board with Standard SODIMM unbuffered DDR2  or with discrete chips.

Yes you can.
The MPC8360 reference manual says: The fully programmable DDR SDRAM controller supports most JEDEC standard ×8, ×16, or ×32 DDR2 and DDR memories available. In addition, unbuffered and registered DIMMs are supported. However, mixing different memory types or unbuffered and registered DIMMs in the same system is not supported. It also provides supported configurations

I provides some design resources, including schematics of board with DDR2 SODIMM
