I have a question for the users of the ethernut development board and for those who have built it from scratch. Is the ATmega103 pin for pin compatible with the ATmega128? Can you do a direct replacement for the old 103 on the board schematic?

Thank You in advance

Hi,

The mega128 is pin for pin compatible with the mega103. The mega128 even comes from the factory with fuses set such that the mega128 operates in mega103 compatibility mode. Careful though, it also comes with fuses set to select an internal oscillator. The datasheet covers this subject very thoroughly (in my opinion).

Regards,
Steve
