DS1682 Overview
The DS1682 is an integrated elapsed-time recorder containing a factory-calibrated, temperature-pensated RC time base that eliminates the need for an external crystal. Using EEPROM technology to maintain data in the absence of power, the DS1682 requires no backup power source. The DS1682 detects and records the number of events on the EVENT pin and the total cumulative event time since the DS1682 was last reset.
