TMS320DM8168: Maximum DDR density support

Rohith Ravi

Part Number: TMS320DM8168

Hi,

In our board currently the DDR3 density support/ we are using is 1GB by making use of the DDR0 controller connected to 4 x 8bit DDR3 chips, each with density of 256MB (256MB x 4 = 1GB). We would like to confirm if we can support 2GB density for DDR by replacing the 256MB chips with 512MB chips.

Also what are the changes that needs to be done in software for this DDR size increase.

Thanks & Regards,

Rohith M Ravi

Hi,

Reading the datasheet, it is able to support 2GB.

Please also note that we no longer provide direct support for this device on e2e forum. You may search the E2E forum for archived posts of previous discussions which may help address your questions. Please also feel free to reach out the 3rd parties listed for additional support.

Hi Charles,

Thank you for the support. But the highlighted section in datasheet seems to mention 2Gb (256MB) not 2GB. Is there any way to confirm if we can support 2GB total RAM with our present configuration?

I understand that there will be no direct support from TI for this product and so for future queries we will go to Third Parties listed.

Thanks & Regards,

Hi,

Sorry, I don't have much experience with this device. Reading the TRM, it does mention the maximum memory space will only be 1GB, not 2GB.
