AM3505 with LPDDR

Ayumi Namiki

Other Parts Discussed in Thread: AM3505, AM3703

Hi,

I would like to know how to treat the following pins of AM3505 when using LPDDR.

- SDRC_DQS0N / SDRC_DQS1N / SDRC_DQS2N / SDRC_DQS3N

- SDRC_ODT

Need PD/PU externally, or NC is OK?

Regards,

Ayumi

Hello Ayumi,

for the DQSxN lines it would be best to pull those down if unused to keep them from floating.

for the ODT like you can leave that as NC as this is an output.
