DDR3L SDRAM interface with iMX6

mrudangshelat — Wed, 23 Mar 2016 04:42:20 GMT

Hi, I am using DDR3L SDRAM with 32 bit interface with iMX6 in my design. iMX6 has 64bit data capacity. If i am using only 32 bit channel 0, so do i need to keep NC channel1 or is there any specific connections/level i need to do in my design. Thanks, Mrudang

Hello,

Unused signals / pins of 64-bit memory I/F (in 32-bit or 16-bit mode) may be left float,
as stated in section 5 (DRAM interface requirements for migration) of app note AN4397

(Common Hardware Design for i.MX 6Dual/6Quad and i.MX 6Solo/6DualLite).

Have a great day,
Yuri

Hi Yuri,

Thanks for prompt support.

I have tried to open new request but due to some issue it's not accepting my User name and password.

Could you please provide me your email address or alternate contact details, so I can send you PDF file for review.

And I am also not able to attach PDF design file with this message.

Thanks & regards,

Mrudang
