[EDIT]
thanks for the info
i have a hex to load in the chip but i don't have its source code , can i add to it extra code to do this :
at each startup read timer 0 , if its value superior to a specified amount of time then clear vector ram or external ram ,one is enough
i want to do this , because i will send my microcontroller to some people ,so to prevent abuse i want it to last only 3 months then destroy itself
i'm ready to change to any secure microcontroller to do this ,the original is DS5000FP
