funcard datasheet
Hello to all!
I try to implement a smart card operating system for the Funcard 163 which contains a ATMega 163 and a 24C256 external EEPROM. Due to have enough memory for a smart card filesystem I want to use the external EEPROM, but I have difficulties accessing the EEPROM. Can anyone tell me which Pins of the ATMega are used to interface the EEPROM? Also a view hints about the timing of the EEPROM would be usefull.
Thanks in advance to everybody who helps me!
greetings
