GENERAL DESCRIPTION

FEATURES

Integrated NV SRAM, RTC, Crystal, Power-Fail

Control Circuit, and Lithium Energy Source

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 byte-wide

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.

Clock Registers are Accessed Identically to the

Static RAM; These Registers are Resident in the

16 Top RAM Locations

Totally Nonvolatile with Over 10 Years of

Operation in the Absence of Power

Precision Power-On Reset

Programmable Watchdog Timer and RTC Alarm

BCD-Coded Year, Month, Date, Day, Hours,

Minutes, and Seconds with Automatic Leap Year

Compensation Valid Up to the Year 2100

Battery Voltage Level Indicator Flag

Power-Fail Write Protection Allows for 10%

Pin Configurations appear at end of data sheet.
