www.DataSheet4U.com CAT24AA01, CAT24AA02 1-Kb and 2-Kb I2C CMOS Serial EEPROM FEATURES „ Supports Standard and Fast I C Protocol „ 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 „ RoHS-compliant TSOT-23 5-lead and SOIC 8-lead packages For Ordering Information details, see page 12. 2 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.
