16bit DDR4 single chip use on I.MX8 MINI (MIMX8MM5CVTKZAA)

[Kumar1]

Hi Sir/Mam,

In my design I am using I.MX8 MINI(MIMX8MM5CVTKZAA (QuadLite)) which has 32bit DRAM interface. 1. Can I use one 16bit DDR4 chip in Mini 8 processor?

2. If I use 16bit single chip DDR4, what about other DDR pins in CPU (16 -31 bit), Can I leave float or need any pullup and pulldown on those pins(DQ16-DQ31/ DQS2-DQS3/DM2-DM3 ?

3. And also can you suggest on terminate resistors, I am using NXP EVK board(8MNANOD4-EVK-DF-SCH) as a reference in that terminate resistor are not placed, Not required ?

4. Or 32 bit DDR4 chip have to use ?
