32k X 8 Autostore Nvsram With Real-time Clock

The Simtek STK1744 DIP module houses 256Kb of nonvolatile static RAM, a Real-Time Clock (RTC) with crystal and a high-value capacitor to support sys- tems that require high reliability and ease of manu- facturing. READ and WRITE access to all RTC functions and the memory is the same as a conven- tional x 8 SRAM The highest eight addresses of the RAM support Clock Registers for centuries, years, months, dates, days, hours, minutes and seconds. Independent data resides in the integral Nonvolatile Elements at all times. Automatic RECALL on power up transfers the Nonvolatile Elements data to the SRAM while an Automatic STORE on power down transfers SRAM data to the Nonvolatile Elements. A software RECALL and STORE are also possible on user command. nvTime allows unlimited READ and WRITE accesses to SRAM unlimited RECALLs and 106 STOREs. By Unkown
