Description

The digital window watchdog timer, ATA5021, is designed in Atmel

®’s state-of-the-art

0.8 µm SOI technology SMART-I.S.™1. In applications 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

watchdog timer within a defined time window.

A missing or a wrong trigger signal causes the watchdog timer to reset the microcon-

troller. The IC is tailored for microcontrollers, which can work in both full-power and

sleep mode. With an additional voltage monitoring (power-on reset and supply voltage

drop reset), the ATA5021 offers a complete monitoring solution for micro-systems in

automotive and industrial applications.
