CAT24AA04, CAT24AA08
4-Kb and 8-Kb I2C CMOS
Serial EEPROM
Description
The CAT24AA04/24AA08 are 4Kb and 8Kb CMOS Serial
EEPROM devices internally organized as 512x8/1024x8 bits.
They feature a 16byte page write buffer and support 100 kHz,
400 kHz and 1 MHz I2C protocols.
In contrast to the CAT24C04/24C08, the CAT24AA04/24AA08
have no external address pins, and are therefore suitable in
applications that require a single CAT24AA04/08 on the I2C bus.
Features
Standard and Fast I2C Protocol Compatible
Supports 1 MHz Clock Frequency
1.7 V to 5.5 V Supply Voltage Range
16Byte Page Write Buffer
Hardware Write Protection for Entire Memory
Schmitt Triggers and Noise Suppression Filters on I2C Bus Inputs

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. The DC input voltage on any pin should not be lower than 0.5 V or higher than VCC + 0.5 V. During transitions, the voltage on any pin may
undershoot to no less than 1.5 V or overshoot to no more than VCC + 1.5 V, for periods of less than 20 ns.

4. When not driven, the WP pin is pulled down to GND internally. For improved noise immunity, the internal pulldown is relatively strong;
therefore the external driver must be able to supply the pulldown current when attempting to drive the input HIGH. To conserve power, as
the input level exceeds the trip point of the CMOS input buffer (~ 0.5 x VCC), the strong pulldown reverts to a weak current source.
