Thomas,

You need to contact one of our FAEs!

See below,

Aust> Hi,

Better than 100Krad. Ask for the FAE for radiation test results.

No, it is not. Some competitors are spreading information that is patently false, and misleading (there, I said it). They compare us with commercial SRAM, which is false and misleading, as we are not commercial SRAM, have nothing to do with commercial SRAM, and do not use commercial SRAM technology or cells. We use our own design cmos configuration latches, which are shown to be 20X to 100X more robust for the same technology. As for their own tests, they only talk about their fuses, and not their logic, or flip flops. How fair is that? With a part that is one tenth the size of ours. Tens times smaller, is also ten times fewer upsets.

How to lie with numbers.

OK, let us try it: Competitors? What is your cross section for logic? Cross section for flip flops? Cross section for config bits, RAM? Go ahead, let us all know your data. Ours is very simple, you can not upset our logic or flip flops as they are so heavily loaded. And the rest of our data is in the power point MAPLD presentation that RK has so kindly provided the link to.

Austin,

Are you sure this is true for BRAM? As I understood it, the readback logic for the BRAM >

Ray,

As we all know, I am certainly not perfect, so I could be wrong here. I am checking. I was pretty confident that changing the address while trying to read hte LUTs affected the contents as they have to share circuitry, but the BRAM is a two port plus the config access, or really a three port memory as the addressing of the config is independent.

I will post as soon as I know for sure....

Aust> Austin,

Wow Austin, you really should cut down on the caffeine!!!

Ralph,

Would you believe I drink decaf? Hard to imagine.

Ralph,

is it really needed to full quote 90 lines of nearly unrelated text. This only fills up the archives with redundancy and makes them hard to search.
