DS1683S+

General Description
The DS1683 is an integrated elapsed-time recorder containing a factory-calibrated, low-temperature-coefficient RC time base that eliminates the need for an external crystal. Using EEPROM technology to maintain data in the absence of power, the DS1683 requires no backup power source.
The DS1683 detects and records the num ber of falling edge transitions on the EVENT pin as well as the total cumulative time that the EVENT pin is held high.Benefits and
Features Records the Total Time the EVENT Input Has Been Active High and Number of Events (Falling Edges of EVENT) That Have Occurred 32-Bit, Nonvolatile, Elapsed Time Counter (ETC) Monitors Event Duration with Quarter Seconds Resolution and Provides 34 Years of Total Time Accumulation Nonvolatile 16-Bit Event Counter Records the Number of Falling Edges Seen by the EVENT Pin Calibrated, Low-Temperature-Coefficient RC Time Base 16 Bytes of User EEPROM Password Protection Scheme (4 Bytes) I2C-Compatible Interface +2.5V to +5.5V Operating Voltage RangeApplications High-Temp, Rugged, Industrial Applications Where Vibration or Shock Could Damage a Quartz Crystal Any System Where Time-of-Use is Important to Track Power-on-Time Recorder
