Hi, I have never used the PIC before so I have some basic questions. I noticed in online mail-order catalogs that there are several varieties of PIC16f84's. I was able to figure out the differences between some of these (mhz rating and packaging, etc.) but I need to know what the difference between the PIC16F84-04/P and PIC16F84-04I/P is. What's the difference between /P and I/P? thanks for your help, Pat Lu
