Part Numbering System
The AVR microcontroller family has an uniform part numbering system for all members of the family. Figure A-1 shows the details of the part numbering system. Table A-1 explains the coding for the amount of EEPROM and SRAM data memory.
The CPU and peripheral resources of the first members of the AVR microcontroller family are listed in Table A-2.
