GENERAL DESCRIPTION
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.
