Product Summary

The X20C04P-25 is a 512 x 8 NOVRAM featuring a static RAM overlaid bit-for-bit with a nonvolatile electrically erasable PROM (E2PROM). The X20C04P-25 is fabricated with advanced CMOS floating gate technology to achieve low power and wide power-supply margin. The X20C04DM-20 features the JEDEC approved pinout for bytewide memories, compatible with industry standard RAMs, ROMs, EPROMs, and E2PROMs.

Parametrics

X20C04P-25 absolute maximum ratings: (1)Temperature under Bias: -65℃ to +135℃; (2)Storage temperature: -65℃ to +150℃; (3)Voltage on any pin with respect to VSS: -1V to +7V; (4)D.C. output current: 10mA; (5)Lead temperature (soldering, 10 seconds): 300℃.

Features

X20C04P-25 features: (1)High Reliability: endurance: 1,000,000 Nonvolatile Store Operations; retention: 100 Years Minimum; (2)Power-on Recall: E2PROM data automatically recalled into SRAM upon power-up; (3)Lock Out Inadvertent Store Operations; (4)Low Power CMOS: Standby: 250μA; (5)Infinite E2PROM Array Recall, and RAM Read and Write Cycles; (6) Compatible with X2004.
