1. Description
The digital window watchdog timer, ATA5021, is designed in Atmel
0.8 µm SOI technology SMART-I.S.
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.
