CAT24AA08WI-GT10

4-Kb and 8-Kb I2C CMOS Serial EEPROM

ON Semiconductor 

CAT24AA04, CAT24AA08

4-Kb and 8-Kb I2C CMOS

Serial EEPROM

Description

The CAT24AA04/24AA08 are 4−Kb and 8−Kb CMOS Serial

EEPROM devices internally organized as 512x8/1024x8 bits.

They feature a 16−byte 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

• 16−Byte Page Write Buffer

• Hardware Write Protection for Entire Memory

• Schmitt Triggers and Noise Suppression Filters on I2C Bus Inputs

(SCL and SDA)

• Low Power CMOS Technology

• 1,000,000 Program/Erase Cycles

• 100 Year Data Retention

• Industrial Temperature Range

• TSOT−23 5−lead and SOIC 8−lead Packages

• These Devices are Pb−Free, Halogen Free/BFR Free, and RoHS

Compliant
