No I2C-address is mentioned in the whole datasheet; all the timing diagrams put the memory offset to the place where one would expect the I2C-address; the pins usually named A0-A2 are not connected... Maybe it once made the chip one cent cheaper, I dunno, but I wouldn't be that surprised :) Doesn't really matter for at24, luckily. Kind regards, Wolfram -- Dipl.-Ing.
