GENERAL DESCRIPTION

FEATURES

The DS1678 real-time clock (RTC) event recorder ꢀ Real-Time Clock/Calendar in Binary-Coded

records the time and date of a nonperiodic,

asynchronous event each time the INT pin is

activated. The device records the seconds, minutes,

hours, date, day of the week, month, year, and

century when the first event occurs, and starts the 16-

bit elapsed time counter (ETC). Subsequent events

trigger the recording of the ETC into the event-log

memory. This allows for up to 1025 events to be

logged. Events can be logged while the device is

Decimal (BCD) Format Counts Seconds,

Minutes, Hours, Date, Month, Day of the

Week, and Year with Leap Year

Compensation and is Year 2000 Compliant

ꢀ

Logs Up to 1025 Consecutive Events in Read-

Only Battery-Backed Memory

User-Programmable Event Trigger can be

Triggered by the Falling Edge, Rising Edge,

or Rising and Falling Edges of the INT Pin

operating from either V_CCor V_BAT

ꢀ

Event Counter Register Provides Data on the

Number of Events that Have Been Logged in
