Product 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).
