DESCRIPTION

The CAT24C256 is a 256-Kb Serial CMOS EEPROM, internally organized as 32,768 words of 8 bits each.

It features a 64-byte page write buffer and supports both the Standard (100 kHz) as well as Fast (400 kHz) 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.
