Abstract :
In this paper, we describe an architecture of a microcontroller called MAPS which answers the safety criterions of the signalling railway industries. MAPS has been designed by using, on the same chip and for the first time, thanks to the UBIST technique, a self-checking circuit and two fail safe interfaces.
