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 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 microcontroller. 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 Atmel ATA5021 offers a complete monitoring solution for micro-systems in automotive and industrial applications. |
