<p>Device for monitoring the functioning of a microprocessor, comprising a cascade arrangement of two monostable flip-flops (1,2) which can both be retriggered, and whose pulse times (t1, t2) define a time window inside which must lie the period of the pulses coming from the microprocessor (3) to be monitored, and supplying as output (18) a reinitialisation pulse for the microprocessor if this is not the case, characterised in that the said device further comprises an initialisation circuit (6) arranged in order to supply a pulse to the initialisation inputs (8, 9) of the flip-flops (1, 2) when the device is switched on. <IMAGE></p> |
