TDA4VM: LPDDR4 Byte swapping

John H. Gardner

Part Number: TDA4VM

Question from customer regarding LPDDR4:

Is byte lane swapping is possible for better routing?


They examined TRM, it indicated that it is possible but didn't see the details.  They also review the SDRAM layout guidelines, which stated that it is only possible in case of DDR3/LPDDR3 and DDR4 but NOT allowed/possible for LPDDR4.
