... DEVICE/PAGE ADDRESSES (A2, A1, A0): The A2, A1, and A0 pins are device address inputs that are hardwired (directly to GND or to Vcc) for compatibility with other Atmel AT24Cxx devices. When the pins are hardwired, as many as eight 2K devices may be addressed on a single bus system. (Device addressing is discussed in detail under “Device Addressing,” ...

... Memory organization Atmel AT34C02C, 2K Serial EEPROM: The 2K is internally organized with 16 pages of 16 bytes each. Random word addressing requires a 8-bit data word address. 4. Device operation CLOCK and DATA TRANSITIONS: The SDA pin is normally pulled high with an external device. Data on the SDA pin may change only during SCL low time periods (see a start or stop condition as defined below ...

... The device address word consists of a mandatory one-zero sequence for the first four most-significant bits (1010) for normal read and write operations and 0110 for writing to the write protect register. The next three bits are the A2, A1, and A0 device address bits for the Atmel AT34C02C EEPROM. These three bits must compare to their corresponding hard-wired input pins. ...
