GENERAL DESCRIPTION
The DS1553 is a full-function, year-2000-compliant
(Y2KC) real-time clock/calendar (RTC) with an RTC
alarm, watchdog timer, power-on reset, battery
monitor, and 8k x 8 nonvolatile static RAM. User
access to all registers within the DS1553 is
accomplished with a bytewide interface as shown in
Figure 1. The RTC registers contain century, year,
month, date, day, hours, minutes, and seconds data in
24-hour BCD format. Corrections for day of month and
leap year are made automatically.
ORDERING INFORMATION
