DS1501/DS1511  
Y2K-Compliant Watchdog  
Real-Time Clocks  
GENERAL DESCRIPTION  
FEATURES  
.
BCD-Coded Century, Year, Month, Date, Day,  
Hours, Minutes, and Seconds with Automatic  
Leap-Year Compensation Valid Up to the Year  
2100  
The DS1501/DS1511 are full-function, year 2000-  
compliant real-time clock/calendars (RTCs) with an  
RTC alarm, watchdog timer, power-on reset, battery  
monitors, 256 bytes NV SRAM, and a 32.768kHz  
output. User access to all registers within the  
DS1501/DS1511 is accomplished with a byte-wide  
interface, as shown in Figure 8. The RTC registers  
contain century, year, month, date, day, hours,  
minutes, and seconds data in 24-hour binary-coded  
decimal (BCD) format. Corrections for day of month  
and leap year are made automatically.
