nvTime™  
32K x 8 AutoStore™ nvSRAM  
with Real-Time Clock  
PRELIMINARY  
DESCRIPTION  
FEATURES  
• Data Integrity of Simtek nvSRAM Combined  
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.  
with Full-Featured Real-Time Clock  
• Stand-Alone Nonvolatile Memory and Time-  
Keeping SolutionNo Other Parts Required  
• No Batteries to Fail  
• Fast 25ns, 35ns and 45ns Access Times  
• Software- and AutoStore™-Controlled  
Nonvolatile Cycles  
• Year 2000 Compliant with Leap Year  
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  
Compensation  
• 24-Hour BCD Format  
• 100-Year Data Retention over Full Industrial  
Temperature Range  
• Full 30-Day RTC Operation on Each Power  
Loss  
• Single 5V ± 10% Power Supply
