Hi,

Is there an update to the sprabl2.zip files to support 4Gbit DDR3 running at 1600M?

I'm using 4, 16-bit wide, 4Gbit DDR3s to implement a 64-bit DDR3 interface on the TMS320C6678.

Thanks,

Noam

Hi Noam,

As per usage note 14 in the C6678 errata document, the DDR3 interface is limited to a maximum transfer rate of 1333 MT/s.

Regards, Bill

Since the recent release of document sprabl2 (KeyStone I DDR3 Initialization (Rev. E) ) it would appear that the embedded link to the calculation spread sheet is once again broken: www.ti.com/.../sprabl2

Could you let me know where to download it from?

Hi SimonPack,

We're working to get the link fixed. Until then, you can down load the spreadsheet from here.

Regards,

Bill

Thanks Bill, but unfortunately that link doesn't work either.

Cheers,

Simon

Hi Simon,
I'm sorry for the problem. I checked the link and it had some additional characters which were causing it to fail. Those have been removed. Try the link again and see if that helps.
Regards,
Bill
