Radiation + CoolRunner2 CPLD?

Started by Bob October 4, 2005
Hi I know that the CoolRunner2 CPLD TQ144, XC2C256-7TQ144I is not
designed to be radiation tollerent, but...

I would be interested if anyone reading this has ever radiated a CPLD
or know of some CPLD radiation data on the web.
I have google searched but found very little.
Most ics like 74hc04 parts can take about 10,000 or more rads of total
dose (Co60).
I hope to do some total dose testing this month.
Also as it has a reprogramable memory, it will be suseptible to SEU.
I wont be able to test for that.

(Not Real) 'Bob',

If you want an answer to this, why haven't you already contacted our 
Xilinx Aerospace/Defense Field Applications Engineers?

We have plenty of data that we are willing to share with (Real) 'customers'.

If you need a contact, I can send their name to you once you email me 
your (Real) 'Bob' email address (and real affiliation).

It is Xilinx' interest to be sure that any aerospace/defense application 
(as well as any other) of our products uses all of the best information 
that we can provide.

Sorry I don't use (real) info on newsgroups to keep spam to a minimum.
I will email you with my (real) contact info.
However I have tried before and was told that there was no info on the
CoolRunner 2 as it is not intended for radiation and there are other
parts that are designed for radiation. However that was last year.
I have also searched on the NASA and ERRIC web sites and was
unsuccessful in finding data.

(Real) Bob,

Thanks for sending to me directly.

There is an aerospace/defense FAE who will contact you shortly to 
provide you with what you need (if we have what you need).

I know we had Coolrunner II in the LANSCE facility in May of this year, 
as it was my group that set it up, and was there for the testing.
