ATA5021 - Digital Window Watchdog Timer

Description

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.

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.
  • Single wake-up input.
  • Reset output.
  • Enable output 9145I-AUTO-10/14 1.
