FEATURES  
DESCRIPTION  
Fast Access Time: 35ns, 45ns, 55ns  
High Reliability  
The Xicor X20C05 is a 512 x 8 NOVRAM featuring a  
high-speed static RAM overlaid bit-for-bit with a non-  
volatile electrically erasable PROM (E2PROM). The  
X20C05 is fabricated with advanced CMOS floating  
gate technology to achieve high speed with low power  
and wide power-supply margin. The X20C05 features  
the JEDEC approved pinout for byte-wide memories,  
compatible with industry standard RAMs, ROMs,  
EPROMs, and E2PROMs.  
Endurance: 1,000,000 Nonvolatile Store  
Operations  
Retention: 100 Years Minimum  
Power-on Recall  
—E2PROM Data Automatically Recalled Into  
SRAM Upon Power-up  
AUTOSTORE™ NOVRAM  
User Enabled Option  
The NOVRAM design allows data to be easily trans-  
ferred from RAM to E2PROM (store) and E2PROM to  
RAM(recall). Thestoreoperationiscompletedin5msor  
less and the recall operation is completed in 5µs or less.  
Automatically Stores SRAM Data Into the  
E2PROM Array When VCC Low Threshold is  
Detected  
Open Drain AUTOSTORE Status Output Pin  
Software Data Protection  
Xicor NOVRAMS are designed for unlimited write  
operations to RAM, either from the host or recalls from  
E2PROM, andaminimum1,000,000storeoperationsto  
the E2PROM. Data retention is specified to be greater  
than 100 years.  
Locks Out Inadvertent Store Operations
