The CAT24C128 is a 128-Kb Serial CMOS EEPROM, internally organized as 16,384 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).
