CAT24AA16

EEPROM Serial 16-Kb I2C

Description

The CAT24AA16 is a EEPROM Serial 16−Kb I2C 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
