PRELIMINARY  
DS1747/DS1747P  
Y2KC Nonvolatile Timekeeping RAM  
www.dalsemi.com  
FEATURES  
PIN ASSIGNMENT  
Integrated NV SRAM, real time clock,  
crystal, power-fail control circuit and lithium  
energy source  
Clock registers are accessed identical to the  
static RAM. These registers are resident in the  
eight top RAM locations.  
Century byte register; ie., Y2K compliant  
Totally nonvolatile with over 10 years of  
operation in the absence of power  
BCD coded century, year, month, date, day,  
hours, minutes, and seconds with automatic  
leap year compensation valid up to the year  
2100
