The 24C02 eeprom has room for twice the amount of data that a 24C01
does. Either the supplier sent you the wrong part, or the original
eeprom had lots of empty space so they replaced it with a cheaper
version of the chip (24C01). I have no idea which, but I'd lean towards
them sending you the wrong part.
