You mean the SecureMicro and Soft Microcontroller devices? The SDI (Self
Destruct Input) just wipes the encryption key and interrupt vector RAMs if it
gets triggered. The idea is you have a few microswitches inside a device's
casing, all wired up to SDI. If one of the microswitches opens - bye bye
code - chip reprogram time.
The really fun bit is, once SDI gets tripped, you can't stop the RAM getting
wiped. Much fun :)
Later.
