Does anyone know the temperature and freq stability of the internal 11 osc?
Thanks,
Rob

It's not specified, AFAIK, so it could be anything. If you need a stable internal oscillator you will have to use the Tiny12, or a crystal with the Tiny11.

I'm thinking the 11 osc. is just designed to make the chip work in no critical apps. but I'd still like to see data on it.
The 12 is a lot more expensive chip and we can run an 11 with a ceramic resonator cheaper. Problem is we lose the input ports we want.

There's a graph in the back of the data sheet which describes variation
with voltage and (some samples of) temperature. I think these are
described as "typical" so YMMV.
