You may have thought I was talking about the part, when I was actually stating what I'd like to have in a SOT23-6 micro. Different thing. Jon

You can obviously connect the ISP header to your target instead. Just have to make sure you have the 5V.

And the lack of a bandgap -- no, Vcc won't do. But I appreciate very much your other replies -- particularly on the BOR, which I will look at with your comments in mind. Since the flash cannot be written and therefore no eeprom emulation and no eeprom, you are right that's another issue. But... I think I can live with the problem if that were the only one. Jon

But for gosh sake that darned thing sucks power -- page 146, curve on the page's bottom. Cripes. Jon
