Suggested update to Cmod A7 (v2)

6 posts in this topic

Hi all and Digilent representatives!

I am a "long" user of the Cmod A7 and am quite pleased with it, except for the choice of SRAM.
And on the side I have been playing with another RAM that is easy to use, delivers better performance (about 200 MB/s for the 3.3v version), and more space (8Mbyes) which would be a really nice update to the Cmod-A7.
The new "HyperRAM" (http://www.digikey.com/products/en/integrated-circuits-ics/memory/774?k=hyperram&k=&pkeyword=hyperram&pv142=133&FV=ffe00306%2C1c0011&mnonly=0&newproducts=0&ColumnSort=0&page=1&stock=1&quantity=0&ptm=0&fid=0&pageSize=25) is like a combination between DDR and SRAM, this blog post describes quite nicely (with later posts showing implementation): https://warmcat.com/embedded/hardware/hyperbus/2016/09/02/hyperram.html

What is Digilent's view/thoughts on the usage of HyperRAM instead of the (aging) SRAM?
A quick check seems to suggest that it is about half the price of the SRAM currently used as well. :)

I hope for a fruitful discussion. Best regards!

Hi again @jpeyron,

Have there been any thoughts / discussions internally yet?
I would very much like to know their view on pros / cons / worries.

Best regards, Emil

@Korken,

I'm not privy to any internal Digilent discussions, but I'm going to wager that those answers are not going to be shared/published.  As it is, you may notice that Digilent says nothing about new products they might market until after they are ready for market.  This is a business decision, and appears to be designed to help Digilent maintain a competitive edge.  I'll let them prove me wrong, but my guess is that you  won't hear much more from them.

Hi @Korken,

@D@n is correct. Dan has a good handle on our business process. That being said, I have not heard anything back about your suggestion to change the Cmod A7's SRAM.

cheers,

Jon

No problem, I understand that internal discussions sometimes cannot be shared.
