Hello Oak,

Have you worked with PICs before? If not, then you might want to start with a 16F to get your feet wet then work your way up.

If you search our forum here you will find several examples of clock programs. Some will even work with an 8 pin 12F series. Keep in mind that the size of the PIC will be determined by what will be connected to the PIC. I used an external clock chip on projects I build because I can't risk losing the time and I also need to control daylight saving time automatically. I provide backup power with a coin battery so if the main power is lost, my clock is still running.

I strongly suggest that if you are new to PICs to spend some time reading thru the various posts here and study up.

There are alot of great people on this forum and even some good guru's that will help you out. Just remember they won't do something for you if you haven't shown some effort.

Have a nice day!
