Product Overview
Product Description
The CAT24C256 is a 256-kb Serial CMOS EEPROM, internally organized as 512 pages of 64 bytes each, for a total of 32,768 bytes 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) I2C 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.
