Description
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.
