  • Abstract
    This paper is devoted to the description of the evolution of different commercial microprocessor supervisory circuits under neutron radiation. After the irradiation, the tested devices showed some interesting changes: the increase of supply current and the duty cycles for watchdog timer. It was also observed that in some devices existed threshold voltage hysteresis and their trigger level was not in the usual TTL range of 0-5V.
