Hm... crazy idea for a product like this that would be reprogrammable....

Answer to isolation for programming and to board space for connector....

Create a special bond-out chip for development (or reprogrammability of a=20
production chip) that has contacts on the top (for programming) as well as=
=20
the bottom (soldered in for the application).

Then a probe that fits right over the top of the chip would allow you to=20
reprogram without requiring any additional board space. Just hold the probe=
=20
on the chip, hit the program button, wait a few seconds, and you're all set=
!
