I searched the FAQ's and didn't find an answer so here goes. We have an application that's
currently using an NE556 and several transistors and resistors for timing and logic that we'd
like to replace with a 12F629 using the 4MHz internal clock. We have experience with the
12F629 but the external power to an LM7805 in this application is cycled on and off every 1.2 seconds.

We need to generate a pulse within 50 milli-seconds of power-up; 50 milli-seconds seems like a long time.
Looking at the datasheet, the Oscillation Start-up Timer Period is 25 micro-seconds using the 4MHz
internal clock which looks fine; the Power-up Timer Period is 132 milli-seconds which is a problem. Does the
Power-up Timer Period apply here - i.e. does it take 132 milli-seconds to stabilize?

Thanks,

Craig
