I also though It was 24c02 but when I opened it I realized It is 24c01. Look at the pictures.

I can't see any other 24cXX, could It be integrated into another chip?

This is IC4 on PC board. But It isn't an eeprom, It is an hex buffer/converter (I think).

Sorry mate, the circuit diagram doesn't follow usual protocol and has quite a few chips marked IC4.
