HI,

We are designing an custom board based on i.MX8DXPlus/ i.MX8QXPlus where i wanted to check the compatibility of LPDDR4 part#.

1) i.MX8QxPlus MEK board uses LPDDR4 part# MT53B768M32D4DT-062 AIT:B,

which as configuration as: No of channel 2 with 2 Chip select per channel.

2) We are using LPDDR4 part#IS46LQ32256A-062BLA3 from Mfg# ISSI,

which as configuration as: No of channel 2 with 1 Chip select per channel. Also below are the address table for ISSI part#.

Will it be an issue considering ISSI has single chipselect per channel? Below is the LPDDR4 schematic page attached for your reference.

Let us know your feedback for the same.

Hi Bimal

memories with 1 chip select per channel (single rank) are also supported 

and you can use attached schematic.

Best regards
