CAT24AA01_15 Datasheet, PDF (1/10 Pages) ON Semiconductor – 1-Kb and 2-Kb I2C CMOS Serial EEPROM

CAT24AA01, CAT24AA02
1-Kb and 2-Kb I²C CMOS
Serial EEPROM
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 the Standard
(100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) 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.
Features
• Supports Standard, Fast and Fast−Plus I²C 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
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
