AM387x Power Rail Question - unused DDR port

Paul Koenig
Prodigy 190 points

Hi,

  We’re using only one of the two DDR3 interfaces on this chip.  It isn’t clear to me from the datasheet if I can leave DVDD_DDR[1] un-powered since DDR[1] is unused.  Can you clarify? The datasheet shows core memory and core logic voltage requirements, but it's not clear whether the voltage is need if the port is not used.

Thanks,
Paul
