8-lead packages
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.
For Ordering Information details, see page 12.
