-National claims they have some sort of anti-reverse engineering protection with their die ID scheme. Who knows if it does anything useful.+ 
 +National, Xilinx, and many other vendors have unique per-chip serial numbers stored in some sort of OTP memory on the chip. The user's firmware presumably uses this in a licensing scheme. Might make for a halfway decent anti-cloning system (until the check is found and nopped out) but is useless for preventing RE.
