DESCRIPTION
The CAT24AA01/24AA02 are 1-Kb and 2-Kb CMOS Serial EEPROM devices internally organized as 128x8/256x8 bits. They feature a 16-byte page write buffer and support both the Standard (100kHz) and the Fast (400kHz) I2C protocols. In contrast to the CAT24C01/24C02, the CAT24AA01/24AA02 have no external address pins, and are therefore suitable in applications that require a single CAT24AA01/02 on the I2C bus.
