The 24CW32X provide 32 Kbits of Serial EEPROM utilizing an I2C (2-wire) serial interface. It is organized as 4096 bytes of 8 bits each (4 Kbytes). The 24CW Series is optimized for use in consumer and industrial applica- tions, where reliable and dependable nonvolatile mem- ory storage is essential. The 24CW Series allows up to eight devices to share a common I2C (2-wire) bus and is capable of operation across a broad voltage range (1.6V to 5.5V).
The 24CW Series contains a pair of programmable Configuration registers which allow certain device behaviors to be modified. These registers are the Write Protection Register and the Hardware Address Register.
