DESCRIPTION

The Xicor X24C45 is a serial 256 bit NOVRAM featuring

a static RAM configured 16 x 16, overlaid bit-by-bit with

a nonvolatile E

with Xicor’s Advanced CMOS Floating Gate technology.

The Xicor NOVRAM design allows data to be transferred

between the two memory arrays by means of software

commands or external hardware inputs. A store opera-

tion (RAM data to E

The X24C45 also includes the AUTOSTORE feature, a

user selectable feature that automatically performs a

store operation when V

Xicor NOVRAMs are designed for unlimited write opera-

tions to RAM, either from the host or recalls from E

and a minimum 1,000,000 store operations. Inherent data

retention is specified to be greater than 100 years.
