CAT24C256

256 kb I²C CMOS Serial

EEPROM

Description

The CAT24C256 is a 256 kb Serial CMOS EEPROM, internally

organized as 32,768 words of 8 bits each.

http://onsemi.com

It features a 64−byte page write buffer and supports both the

Standard (100 kHz) as well as Fast (400 kHz) I C protocol.

Write operations can be inhibited by taking the WP pin High (this

protects the entire memory).

External address pins make it possible to address up to eight

CAT24C256 devices on the same bus.
