Has anyone seen information on the PIC12C5XX products beyond what's in the Product Brief sheets? I'm interested in knowing more about the 4 MHz Internal RC oscillator option. Specifically, how stable is the frequency over the temperature ranges normally found in a home environment, say 10C-38C? I have an application that does some timing and as long as it were within a minute or two over a 10 hour period it would work out well and would benefit from not needing external oscillator circuitry.
