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 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.
Pin Configurations appear at end of data sheet.
FEATURES
§ Integrated NV SRAM, RTC, Crystal, Power-Fail
Control Circuit, and Lithium Energy Source
§ 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%
VCC Power-Supply Tolerance
§ Lithium Energy Source is Electrically
Disconnected to Retain Freshness Until Power is
Applied for the First Time
