The Intersil X24C45 is a serial 256-bit NOVRAM featuringa staTIc RAM configured 16 x 16, overlaid bit-by-bitwith a nonvolaTIle EEPROM array. The X24C45 is fabricatedwith Intersil’s Advanced CMOS FloaTIng Gatetechnology.The Intersil NOVRAM design allows data to be transferredbetween the two memory arrays by means ofsoftware commands or external hardware inputs. Astore operaTIon (RAM data to EEPROM) is completedin 5ms or less and a recall operation (EEPROM data toRAM) is completed in 2μs or less.The X24C45 also includes the AUTOSTORE feature, auser selectable feature that automatically performs astore operation when VCC falls below a preset threshold.Intersil NOVRAMs are designed for unlimited writeoperations to RAM, either from the host or recalls fromEEPROM and a minimum 1,000,000 store operations.Inherent data retention is specified to be greater than100 years.
