... DEVICE/PAGE ADDRESSES (A2, A1, A0): The AT24C04B uses the A2 and A1 inputs for hard wire addressing and a toal of four 4K devices may be addressed on a single bus system. The A0 pin connect and can be connected to ground (device addressing is discussed in detail under the Device Addressing section). ...

... EEPROM in 8-bit words. The EEPROM sends a zero to acknowledge that it has received each word. This happens during the ninth clock cycle. STANDBY MODE: The AT24C04B/08B features a low-power standby mode which is enabled: (a) upon power-up and (b) after the receipt of the STOP bit and the completion of any internal operations ...
