U5020M Datasheet (TEMIC Semiconductors) - Digital Window Watchdog Timer

U5020M, Digital Window Watchdog Timer

The digital window watchdog timer, U5020M, is a CMOS integrated circuit.

In application where safety is critical, it is especially important to monitor the microcontroller.

Normal microcontroller operation is indicated by a cyclically transmitted trigger signal, which is received by a window watchdo
