CAT24C256

EEPROM Serial 256-Kb I

Description

The CAT24C256 is a EEPROM Serial 256−Kb I

C, internally

organized as 32,768 words of 8 bits each.

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

(100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) 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.

On−Chip ECC (Error Correction Code) makes the device suitable

for high reliability applications.*
