Hi, Is there a single chip LPDDR4 4GByte RAM chip that is compatible with the iMX8M-Mini processor?
The i.MX 8M Mini supports x32/16 bit DRAM interfaces. LPDDR4 is essentially dual channeled; using single channel means half of memory is lost. About the LDDR4 configure you can see the script here:
i.MX8 MSCALE SERIES DDR Tool Release (V2.10)
Hi, Thanks for the info. I'm trying to decide which memory to use to design the iMX8M-Mini with 4GBytes RAM. I can only find x32 4GB parts that are QDP(quad die package) which the iMX8M-Mini doesn't support. The largest DDP (dual die package) LPDDR4 i can find is 2GB. What RAM configuration would you suggest i use to get 4GB RAM please?
Did you checked MT53D1024M32xxx? It has the same datasheet with DDR4 used in the reference design. I guess i.mx8 mini has control pins for 4 GByte DDR4 which are shown as NC(not connected) in 2 GB DDR4 schematic page and connected.
Hi, The iMX8M-Mini doesn't support QDP (Quad-Die, Dual-Channel, Dual-Rank Package) and the only 4GByte parts including the one you have mentioned are QDP. In that same datasheet the 2Gbyte part is DDP (Dual-Die, Dual-Channel, Single-Rank Package). I think we are going to go with a single chip 2Gbyte part design and hope a DDP 4Gbyte part is available in the future. Thanks for your input.
