Description
The GSC24BC family provides 1K, 2K, 4K, 8K and 16K of serial electrically erasable and programmable
read-only memory (EEPROM). The wide Vdd range allows for low-voltage operation down to 1.8V. The device,
fabricated using traditional CMOS EEPROM technology, is optimized for many industrial and commercial
applications where low-voltage and low-power operation is essential. The device is accessed via a 2-wire serial
interface.

... Device/Page Addresses (A2, A1, A0): The A2, A1, and A0 pins are used to address multiple devices on a single bus system and should be hard-wired. The GSC24BC01 and GSC24BC02 use the A2, A1 and A0 pins to provide the capability for addressing up to eight 1K/2K devices on a single bus system (please see the Device Addressing section for further details) & ...
