Maxwell makes an entire array of microelectronics components. These are generally meant for use in devices that are deployed into space environments.

Holy shit.
So this is to protect your orbital weapons platform from EMP blasts?

How much does this stuff cost?

I don't think they do regular consumer stuff, it looks like everything is special order. According to this page [1], you have to contact one of their business partners in order to arrange any purchases.

Or anything you feel like putting in space, that you worry might be near a nuclear explosion or other source of intense ionizing radiation at some point. Be prepared, as the boy scouts say. I assume that maxim goes double in space, considering how expensive it is to put things up there in the first place.

#8So, my mom is a former Maxwell employee who now does her own defense contracting, and makes this same type of part.
As I understand it, when there is a nuclear event, it generates x-rays followed by the EMP. The goal is to have warheads in flight to be able to continue to their target, so the strategy is to employ an NED. When an event is detected, the warhead shuts down its electronics for the duration of the EMP, and then powers back up.
With her NED, she uses an ASIC for detection. I might get some details wrong, but the ASIC has a physical array in it, and the x-rays flip bits in the array. When enough bits get flipped, one can infer a nuclear event. Because it is an ASIC it is really small, which has important advantages for space-born avionics.

Remember to declare ned_pin volatile. (Sorry to be pedantic, but I was getting physically uncomfortable about the possibility that it might not have been declared volatile.)

No kidding. I believe NASA had something like 3 dual-redundant flight computers on the Voyager probes.
