Real-Time Event Recorder  
www.maxim-ic.com  
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 VCC or VBAT  
.

Event Counter Register Provides Data on the  
Number of Events that Have Been Logged in
