My customer has designed his system around mobile DDR and is unsure what voltage these pins need to be tied to. I didn’t see any mobile memory app notes and it’s not really clear how to handle the DDR power domain.
More specifically, they started with a 2.5v system, then changed designers, then migrated to 1.8v system.
Can you supply additional guidance?
The following pins supposed to be connected to 2.5v or 1.8v?
