Some time ago i made a built a project that i saw in a website, it was a
frequency meter (pic16f876). I did try with an F and a LF part and with =
a LF
part i could only measure ~25Mhz max and with a F i could measure =
~50MHz,
Later i check the datasheet and i found that the timer (that the pic =
used to
make the measurement) could only read max at 25ns (LF part) and 10ns (F
part). And there are some other timings that the LF part is slower.

Assunto: [PIC:] 18F452 / 18LF452

My supplier states a lead time on 18F452's is a few weeks, but 18LF452's =
are
in stock. As far as I can see from the datasheet an 18LF is the same or
better compared to an 18F. It this correct? Is this generally true for =
all
PICs?
