The device is organized as eight blocks of 256 x 8-bit memory with a 2-wire serial interface. Low voltage design permits operation down to 2.5 volts with standby and active currents of only 5 µA and 1 mA respectively. The 24LC164 also has a page-write capability for up to 16 bytes of data. The 24LC164 is available in the stan- dard 8-pin DIP and 8-lead surface mount SOIC pack- ages. The three select pins, A0, A1 and A2, function as chip select inputs and allow up to eight devices to share a common bus, for up to 128 Kbits total system EEPROM.
