Then when you want to write to the part use an address byte of 0xA0 and when you want to read use an address byte of 0xA1.

So for example you keep A0: In figure 4 they refer to the address as an 8-bit quantity:. Post as a guest Name.

Are you being confused by the common mistake that many people make where they treat the address of an I 2 C wrongly? You do not write 24c40 addresses; you hardwire them. It will answer to address that was set up before powering up.
