GENERAL DESCRIPTION  
FEATURES  
.
Integrated NV SRAM, RTC, Crystal, Power-Fail  
Control Circuit, and Lithium Energy Source  
The DS1553 is a full-function, year-2000-  
compliant (Y2KC) real-time clock/calendar (RTC)  
with an RTC alarm, watchdog timer, power-on  
reset, battery monitor, and 8k x 8 nonvolatile static  
RAM. User access to all registers within the  
DS1553 is accomplished with a byte-wide  
interface as shown in Figure 1. The RTC registers  
contain century, year, month, date, day, hours,  
minutes, and seconds data in 24-hour BCD format.  
Corrections for day of month and leap year are  
made automatically.  
.
Clock Registers are Accessed Identically to the  
Static RAM; These Registers are Resident in the  
16 Top RAM Locations  
.
Totally Nonvolatile with Over 10 Years of  
Operation in the Absence of Power  
.
.
.
