Datasheet in PDF for the 24AA00, 24LC00 and 24C00 serial EEPROMs, the smallest parts of this I2C family with only 128 bits of storage. The letters distinguish voltage grades, and the document covers pins, bus protocol, write timing and electrical limits. Such tiny memories often store an identifier or a few settings, so the sheet helps confirm what the chip is and how to read it. Verify the package marking first, and record the original contents before writing, as the data may be unit specific.
