hi,
using a watch dog timer could we shutdown a microcontroller ?
currently iam using a pic24fj128 microcontorller.
pls reply
 

shutdown you mean sleep?
if yes some mcu have a function when a wdg timer overflow have option like.

In Atmel Mega series mega48 you can do when a WDG timer overflow you can do reset, interrupt, interrupt then reset.

So for your problem you put the interupt option and in interrupt you put the mcu to sleep.

hi
sleep mode i already did.
i wanted to know whether we can shutdown or not .
if not possible using wdt , is there any other method ?
 

What do mean by shutdown?
The Pic24F has a DEEP SLEEP MODE which is as good as turning it off.
You could use an output pin to switch off the power supply.
 

if we are goning to sleep mode the controller will run in a low power state ie, the oscillator will switch to lprc .
actually i don't want to run in a low power state . i want to off the controller . using any other methods could i do that ?
