MAX10 supported DDR3 topology

Hello, I am working on my first implementation of DDR3 memory with MAX10 FPGA. My initial direction was to follow MAX10 FPGA Development Kit with 10M50DAF484C8G on board. The main difference is - I ...

    Hello,


    Yes you can.

    The ECC bit is only set to 8-bit. So you cannot use 4-bit as ECC.

Hello Adzim,

Thank you for your reply. Does it mean that if I do not plan to use ECC I can use only 16-bit DDR3? The Table 3 "Supported Maximum External Memory Interface Width in Intel MAX 10 Device Packages" shows that device I am using (F484 package) can work with DDR3 "with or without" ECC.

I know that not using ECC sounds weird, but I in fact I need 12 bits out of this 16-bit message, so I have 4 bits left for error correction.
