Hello,

I have schematic references for most of LPDDR3 and this MCU but RAM module that I want to use is 8Gb from Micron. And this particular module miss some pins. Its 1 x 8Gb Die module 32bit, ball/pad description attached. As you can see command and address inputs are together. Which means that RAS#, CAS#, WE# pins aren't present and also bank address input pins.

My question is do I connect these CA[9:0] pins on regular address pins on MCU and what to do with rest unused pins on it? (command pins on MCU)
