ATA5021 - Digital Window Watchdog Timer

The digital window watchdog timer, Atmel® ATA5021, is designed in Atmel’s state-of-the-art 0.8µm 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.

ATA5021 Features

* Low current consumption: IVDD < 25µA

* RC oscillator

* Internal reset during power-up and supply voltage drops (POR)

* “Short” trigger window for active mode

* “Long” trigger window for sleep mode

* Cyclical wake-up of the microcontroller in sleep mode

* Trigger input
