GENERAL DESCRIPTION
The DS1678 real-time clock (RTC) event recorder
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
operating from either VCC or VBAT.
PIN CONFIGURATION
FEATURES
Real-Time Clock/Calendar in Binary-Coded
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
Event Counter Register Provides Data on the
Number of Events that Have Been Logged in
the Current Event-Logging Mission
