CAT24AA04 Datasheet, PDF (1/10 Pages) ON Semiconductor – 4-Kb and 8-Kb I2C CMOS Serial EEPROM

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
