1-Kb, 2-Kb, 4-Kb, 8-Kb and

16-Kb I2C CMOS Serial

EEPROM

Description

The CAT24C01/02/04/08/16 are 1−Kb, 2−Kb, 4−Kb, 8−Kb and

16−Kb respectively CMOS Serial EEPROM devices organized

internally as 8/16/32/64 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

CAT24C01 or CAT24C02, four CAT24C04, two CAT24C08 and one

CAT24C16 device on the same bus.

Features

• Supports Standard and Fast I2C Protocol

(SCL and SDA)

• Low power CMOS Technology

• 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
