Description

The N24C256X 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 the Standard

(100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I2C protocol.

The device also features a 128−bit factory−set read−only Unique ID

and Software Write Protection of the entire array. The Unique ID may

be used to identify the manufacturer and the device.
