There is another possibility here for security than just code
protection alone. I have seen some manufacturers disguise what
the chip actually is, either by sanding off the lettering or painting it,
encapsulating in epoxy etc.

The part is then X1, available from the manufacturer as the 'X1 part'.

Would make it harder to even figure what the part was before
attempting to crack it.
