Memory chip

2-Kbit(256 x 8bit), I2C interface, working voltage: 1.7V 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.

The CAT24C08 is an EEPROM serial 8-Kb I2C device internally organized as 64 pages of 16 bytes each. The device supports standard (100 kHz) protocol as well as fast (400 kHz) I2C protocol. Data is written by providing a start address, then loading 1 to 16 consecutive bytes into the page write cache, and then writing all the data to non-volatile memory in an internal write cycle. The way to read data is: provide the start address, then move out the data in order, and automatically increment the internal address count at the same time. External address pins enable addressing of up to two CAT24C08 devices on the same bus.
