The 2.76 MB PDF documents pinouts for each package, fuse bits, clock sources, ISP programming, peripherals and electrical characteristics. It is useful when tracing a controller on a board, checking supply and reset lines, or replacing a chip with a larger family member. Confirm the exact suffix and package on the part before programming.
