Wow, we still use external power supervisor because we need with reset signal for some of ICs placed on PCB (CPLD, output registers, etc). From other side we do still not trust their improvement at 100%.

At least the ED2 reset pin could be used as an output.

About other coments over the tests in few months:
I know that i'm using the device in a very short time, in a nice (not noisy) enviroment. Then i don't want to say "Keep away all your reset circuits. We have found the wheel, the key for all the problems!!"
I only want to tell my experience with ONE device in a new development.

Félix.
