I usually don't use POR, because it is a problem for the test of digital circuit. You need to be able to synchronise your data with the tester.

Hi all,

I need the power on reset circuit, not the application notes or the block diagrams.

A circuit can be a very low current source, a capacitor and a shmitt trigger. After reset, turn of the current source and lock your state.
