General Description

The DS1501/DS1511 are full-function, year 2000compliant 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.
