CAT24AA16
16-Kb I2C CMOS Serial
EEPROM
Description
The CAT24AA16 is a 16−Kb CMOS Serial EEPROM device
internally organized as 2048x8 bits.
The device features a 16−byte page write buffer and supports
100 kHz, 400 kHz and 1 MHz I2C protocols.
Data is written by providing a starting address, then loading 1 to 16
contiguous bytes into a Page Write Buffer, and then writing all data to
non−volatile memory in one internal write cycle. Data is read by
providing a starting address and then shifting out data serially while
automatically incrementing the internal address count.
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
• This Device is Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
