DS1678 Overview
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 16bit elapsed time counter (ETC). Subsequent events trigger the recording of the ETC into the event-log memory.
