ATMEGA8-16PC datasheet, cross reference, circuit and application notes in pdf format.
I have an atmega16-16PC and a atmega16-16PI. The only difference I found between them is that the PI is for industrial use (operating temperatures -40C--80C) and the PC for commercial use (operating frequency 0C--80C). I wasn't expecting to find any differences in terms of programming, but the program I wrote for the PC doesn't work on the PI.
