In a new design I am using the ATmega128 micro. My flash.HEX code is near 30KB, I am also not using more than 20 bytes of internal EEPROM and not more than 1050 bytes of SRAM.
In order to reduce my final product price I would like to switch from the ATmega128 to the ATmega64.
Does anybode has the experience to inform on which things I have to take care? (PINS, Features, Errata, anything else). I am using the IAR Embedded Workbench C Compiler.
The ATmega128 and ATmega64 seem to be similar devices (PIN to PIN, features) except the memories length, althought they are incuded in different areas/datasheet/series, that's why I am asking you.
