    Works fine for me and millions of other folks, both the original 16F877 & 16F877A. What's the problem you're referring to?

    I also started with the 16F84 and moved on to the 877 with no problems except maybe because of my own ignorance. I had some shorts which blew my chip and running 20Mhz on a broadboard or Veroboard was a bit unreliable at times, maybe because of oscillator lockup.

    AFIAK there might be some errata or minor bugs in older chips which you could find on Microchip's site.

    Pic16F877 and Pic16F877A are very reliable and there is no problem with these if someone knows to use it properly. There are 2 Comparators in 877A, not in 877 and if not used, those should be turned off. I have not faced any problem with either 877 or 877A till today.
