X20C04 512 x 8 Bit Nonvolatile Static RAM • High reliability 1,000,000 nonvolatile store operations 100 years minimum • Power-on recall data automatically recalled into SRAM upon power-up • Lock out inadvertent store operations • Low power CMOS 250µA • EEPROM array recall, and RAM read and write cycles • Compatible with X2004 The Xicor X20C04 is a 512 x 8 NOVRAM featuring a t static RAM overlaid bit-for-bit with a nonvolatile electri- cally erasable PROM EEPROM . The X20C04 is fabricated with advanced CMOS gate technology c to achieve low power and wide power-supply margin. The X20C04 features the JEDEC approved pinout for byte-wide memories, compatible with industry stan- u dard RAMs, ROMs, EPROMs, and EEPROMs. The NOVRAM design allows data to be easily transferred d from RAM to EEPROM store and EEPROM to RAM recall . The store operation is completed in 5ms or less and the recall operation is completed in 5µs or less. o Xicor NOVRAMS are designed for unlimited write r operations to RAM, either from the host or recalls from EEPROM, and a minimum 1,000,000 store operations Pto the EEPROM.
