Is it possible to kill a Atmega162V using the fuses?
At first I thought maybe I had inadvertently set the oscillator to external, but that doesn't seem to be the problem.
I somehow managed to kill a Atmega162V the other day.
I was using a AVRISP programmer, and it recognizes the MCU OK, but all attempts at programming the MCU fail.
I even tried hooking up a external crystal oscillator to no avail also.
I eventually removed the MCU and replaced it with a new Atmega161 and the Atmega161 is working fine no problems. I can set fuses and program it no problem.

So you are saying that you can read the signature of the "blown" chip repeatedly and reliably?

If so, you may have inadvertantly blown the lock bits. Try a chip erase.

If not, what do you mean by "recognizes"?

I've never met a pig I didn't like, as long as you have some salt and pepper.

Well, my mistake, I actually meant to say that at first it recognized the MCU, but after I inadvertent programmed the fuses before I set the clock fuse setting, the chip went away.
When I get a chance, I'll hook up a JTAG programmer and see if anything changes.
Otherwise, it's off to the parallel programmer for the chip. Hopefully that will fix it.
Thanks
