2-Mbit(256K x 8bit), SPI interface, working voltage: 2.3V to 3.6V

The CAT24M01 is an EEPROM serial 1-Mb I2C internally organized as 131,072 words of 8 bits each. It has a 256-byte page write cache and supports standard (100 kHz), fast (400 kHz) and ultra-fast (1 MHz) I2C protocols. Write operations can be disabled by pulling the WP pin high (this protects the entire memory). External address pins make it possible to place up to four CAT24M01 devices on the same bus. On-chip ECC (Error Correction Code) makes the device suitable for high-reliability applications.
