ATmega16 Schematic Diagram

This schematic shows the ATmega16 circuit as it was built on the test board. The power supply is common and is shared by all of the MCU's on the board. The ATmega16 is using an external crystal. The circuit applies to the ATmega164 - ATmega1284, and ATmega32 as well. The ATmega16 is the 16k Flash version of the ATmega32, which has 32k Flash.
