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.
