DESCRIPTION
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.
