The min/max internall oscillator frequency is important to me because i
don't want to use external clock (one more circuit). I have read that power
consumption is proportional to the working frequency, and because my
application (some kind of simple thermal management) doesnot need so much
speed (4 MHz) i thought of decreasing the clock freq. . That's why i wanted
to know the internal osc. freq. limits

I know i can decrease power consumption with puting the PIC to Sleep mode
(when i don't need it without decreasing the working freq.), maybe it's the
same thing, i just thought if the above thought was possible.

As far as PIC16F88, sorry i didnot finish reading the manual (my mistake),
but i did so for PIC12F675 and because i thought the internal osc options
might be the same, i just asked! Anyway thank you for the help!!
