DS1500  
Y2K Watchdog RTC with  
Nonvolatile Control  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS1500 is a full-function, year 2000-compliant  
real-time clock/calendar (RTC) with an alarm,  
watchdog timer, power-on reset, battery monitors,  
256 bytes of on-board nonvolatile (NV) SRAM, NV  
control for backing up an external SRAM, and a  
32.768kHz output. User access to all registers within  
the DS1500 is accomplished with a byte-wide  
interface, as shown in Figure 7. 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.
