Product Summary

The DS1678S+ is a real-time clock (RTC) event recorder records the time and date of a nonperiodic, asynchronous event each time the INT pin is activated. The DS1678S+ 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.
