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.
Radiation + CoolRunner2 CPLD?

(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.
