Champ,
AM62x DM and TRM both show AM62x DDRSS can support up to 8GB for DDR4.
Max addressable range
• 8GBytes with DDR4
• 4GBytes with LPDDR4
1.4.3 DDR 16-bit Subsystem (DDR16)
Integrated in MAIN domain: One instance of DDR 16-bit Subsystem (DDR16) (also referred to as DDRSS) is
used as an interface to external SDRAM devices which can be utilized for storing program or data. The DDRSS
provides the following main features:
• Support of LPDDR4 memory type (up to 1600Mbps)
• Support of DDR4 memory type (up to 1600Mbps)
• 16-bit memory bus interface with in-line ECC
• Up to 8 GB memory address range
However, is there one pcs x16 DDR4 chip support 8GB (single die or dual dies are both ok) currently?
Most of 4GB DDR4 chip in market are dual dies solution which means both CS will be used so only one dual dies DDR4 can be used.
Assuming to use 2 pcs 4GB DDR4 x8 chip, is there any 4GB single die DDR4 chip we have ever supported?
