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.

Cꢀ BCD-Coded Century, Year, Month, Date, Day,

Hours, Minutes, and Seconds with Automatic

Leap-Year Compensation Valid Up to the Year

2100

Cꢀ Programmable Watchdog Timer and RTC Alarm
