I'm looking for a rad-tolerant, non-volatile (preferably programmable at once) FPGA or CPLD, for a new project (a satellite instrument).
After searching the Web, I've found out that Actel manufactures micro antifuse FPGAs. These would be fine, but I would like to know if are there any other alternatives besides Actel FPGAs.
The device should have around 2500 user gates or more.
Reliability is a concern to us, and availability of a similar or equivalent, in System Programmable (ISP), part would be a plus.
Any single chip solution (preferably non-reprogrammable, to avoid unintentional program changes, due to radiation) would be fine, including CPLDs.
P.S: ASICs (Field Gate Arrays) would be OK, provided it cost less than US$10,000.00 and takes less than a month or two to be fabricated. In case we opt for an ASIC, only around 3-5 units would be produced.
If you are willing to help, you can e-mail me directly: maaf _att_ dea.inpe.br (replace the _att_ by an @)
Best Regards, Marcio
