General Description
The DS1682 is an integrated elapsed-time recorder con-
taining a factory-calibrated, temperature-compensated
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 num-
ber of events on the EVENT pin and the total cumulative
event time since the DS1682 was last reset to 0. The
ALARM pin alerts the user when the total time accu-
mulated equals the user-programmed alarm value. The
polarity of the open-drain ALARM pin can be programmed
to either drive low or to become high impedance upon an
alarm condition. The DS1682 is ideal for applications that
monitor the total amount of time that a device has been
in operation and/or the number of uses since inception of
service, repair, or the last calibration.
Applications
● High-Temp, Rugged, Industrial Applications Where
Vibration or Shock Could Damage a Quartz Crystal
● Any System Where Time-of-Use is Important
(Warranty Tracking)
Benefits and Features
● Records the Total Time That the Event Input Has
Been Active and the Number of Events That Have
Occurred
● 32-Bit, Nonvolatile, Elapsed Time Counter (ETC)
Monitors Event Duration with Quarter-Second
Resolution and Provides 34 Years of Total Time
Accumulation
● Programmable Elapsed Time ALARM Output
● Nonvolatile, 17-Bit Event Counter Records the Total
Number of Times an Event has Occurred
● Calibrated, Temperature-Compensated RC Time
Base Accurate to 2% Typical
● 10 Bytes of EEPROM User Memory
● Write Disable Function to Prevent the Memory from
Being Changed or Erased
● 2-Wire Serial Communication
● Wide 2.5V to 5.5V Power-Supply Range
● Useful in Time-of-Use Warranty, Calibration, Repair,
and Maintenance Applications
