    Yes I did, however for my project I must have a internal oscillator due to size constraints... Ok, so basicly I am the idiot and I should take a hammer to my head instead of the chip... I don't know why I assumed it had a internal oscillator other than the fact that I have never used mid-range MCU's. Only 16pin and smaller PIC's.

    Know of a 28pin PIC with a accurate internal oscillator off the top of your head?

    Parametric search at Microchip.com
    13 hits on a 16F PIC in a 28 pin package with an internal oscillator block...
    My personal favorite for a 28 pin PIC at the moment wouldn't be a 16F though. It would be a PIC18F2685 (96K of code space) or a PIC18F2550 (USB included)...
    All sorts of options here...

    Another thing...just to verify it all, get it to at least work, you can use the R/C oscillator. Just hang a resistor and a capacitor off the OSC1 pin and see what happens.
    Sure, it's not accurate, but it'll at least verify that your hardware is good.

    I just switched to a 16F690 that I had a PDIP version of as well as a SOIC version. It's a few pins short of what I need but it's fine for testing the final product and the most important thing is, it has a internal oscillator :-)

    I really can't believe I overlooked that and wasted my time and everyone else in here. lol

    I am etching the new prototype board out now after I tested the code working on my development board. Hopefully all goes well!

    Thanks again for your help everyone!
