Thanks for the great explanation

As far as the PIC goes, I have the following

18F14K50
16C745
12F675dsPIC 33FJ120P
16F84
16F676
24FJ64GA002
16F81930F2010
16HV785
If any of these pop out as ones you know would be suitable, please let me know, otherwise I will go searching.

It is not critical that I use the 16F690, its just that it is installed on the LPC demo board.

My project is (what I thought in the start would be simple - now I know otherwise) to save a sinewave in an EEprom and get a value and send it out to the DAC. Then a switch to change the speed of the loop to give 50 or 60 hertz.

Thanks
