This should be a FAQ: I am intentionally "shouting": DON'T OVERCLOCK PICS Bob Ammerman RAm Systems (contract development of high performance, high function, low-level software) ----- Original Message ----- From: Ander To: Sent: Wednesday, March 21, 2001 12:26 PM Subject: [PIC]: 20 MHz clock in a 4 MHz pic Hi. I've allways used 4 MHz pics for my personal proyects, and I've put 1= 4 and 20 MHz clocks on them and they work fine. Now I'm going to use a 16f873 p= ic with a 20 MHz clock in my work. Can I use 4 MHz models or do I have to use 20 = MHz modes? I never had problems with it at home, but my proyects have not bee= n working for days with out stop, so I don't know if they will break after a few da= ys.
