Read some of the threads on this topic, but didn't see any real data....
I'm using a ATtiny88 and just trying to understand the internal-oscillator variation that I'll see over temperature.
So if I OSCAL it at room temp (to +/- 1%), what kind of variation am I likely to see when I deploy it as a Xmas light controller outdoors at -10F ?
The spec has "TBD" data.... anybody have real data or an applicable Atmel spec?
I can design for the variation, but need to know what it will be....
