I'm working on a project involving the 12C509A which would benefit from the BOR watchdog algorithm mentioned below by Peter Peres.

I use these on a steam iron control, and the parts cost is near US$0.03 in volume. Pretty hard to beat. It's not a precise brownout circuit, but my tests have shown it to work reliably. --Lawrence ----- Original Message ----- From: "Peter L.
