DS1500 Y2K-Compliant Watchdog RTC With NV Control

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.
