Atmel have had FPGA devices for a very long time, they also have military specification FPGAs that are probably sat in lots of hardware that would need a constant flow of replacement modules for repair.

I seem to remember that they had some early 8051 and possibly even AVR devices that had some programmable logic blocks on board too.

This reminded me of a cool video I watched the other day, so I made a new post about it - https://news.ycombinator.com/item?id=9486128
