Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.

This is a stress rating only and the functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The Xicor X24C45 is a serial 256 bit NOVRAM featuring a static RAM configured 16 x 16, overlaid bit-by-bit with a nonvolatile E²PROM array. The X24C45 is fabricated with Xicor's Advanced CMOS Floating Gate technology.

The X24C45 also includes the AUTOSTORE feature, a user selectable feature that automatically performs a store operation when V_CC falls below a preset threshold.
