I want to design a board for iMX7D (MCIMX7D7DVM10SD) processor. I want to use total 2GB Mobile LPDDR3 SDRAM. I want to use LPDDR3 from Micron (MT52L256M32D1PF or MT52L512M32D2PF or MT52L1G32D4PG).
There are 3 different configurations for DRAM (1 Gig x 32, 512 Meg x 32, 256 Meg x 32) and I didn't understand well.
Does the configuration 512 Meg x 32 mean that 2GB of total memory on one chip with 2 die? Can I use this chip and have 2GigaByte of memory?
I also don't understand how I connect memory chip and processor:
The memory chip has no BA (Bank Addres), CAS (Column Address Strobe), RAS (Row Address Strobe), WE (write enable), RESET balls. Shall I leave those balls of processors just floating?
The memory chip has only 10 address lines. Would other balls (DRAM_ADDR11 to DRAM_ADDR15) of processor be floating?
The memory chip has only one ODT input. The processor has two ODTs. Shall I connect only ODT0 of processor to chip?
