CAT24C01/D

EEPROM Serial

2/4/8/16Kb I2C

CAT24C02, CAT24C04,

CAT24C08, CAT24C16

Description

The CAT24C02/04/08/16 are 2−Kb, 4−Kb, 8−Kb and 16−Kb

respectively I2C Serial EEPROM devices organized internally as

16/32/64 and 128 pages respectively of 16 bytes each. All devices

support both the Standard (100 kHz) as well as Fast (400 kHz) I2C

protocol.

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.

External address pins make it possible to address up to eight

CAT24C02, four CAT24C04, two CAT24C08 and one CAT24C16

device on the same bus.

Features

• More than 1,000,000 Program/Erase Cycles

• 100 Year Data Retention

• Industrial and Extended Temperature Range

• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS

Compliant
