Precision and dependability are critical in the realm of electronics and industrial applications. Keeping track of time-related data, event counts, and total usage is frequently necessary to ensure the longevity and efficiency of various systems and equipment. This is where the DS1682S+T&R, an elapsed-time recorder, comes into play. In this detailed tutorial, we’ll look at the DS1682S+T&R’s characteristics, benefits, applications, and usage.

Understanding the DS1682S+T&R

The DS1682S+T&R is a built-in elapsed-time recorder that simplifies time tracking and event counting. Here are some of its key features:

● Integrated RC Time Base

The DS1682S+T&R has a temperature-compensated, factory-calibrated RC (Resistor-Capacitor) time basis. This removes the requirement for an external crystal, simplifying the design and lowering expenses.

● Nonvolatile Memory

Data integrity is critical, and the DS1682S+T&R solves this by employing EEPROM technology to keep data even when power is lost. There is no need for a backup power source, ensuring that essential information is always available.

● Event Detection and Recording

The number of events on the EVENT pin can be detected and recorded by this device. It also logs the overall cumulative event time from the last reset to zero.

● Alarm Functionality

The DS1682S+T&R has an ALARM pin that will notify users when the total time accumulated surpasses a user-programmed alarm value. You can even set the polarity of the alert pin to drive low or high impedance in response to an alert condition.

● Wide Range of Applications

The DS1682S+T&R’s adaptability makes it excellent for a wide range of applications, including high-temperature, tough industrial situations where vibrations or shocks could damage a quartz crystal.


Initialization and Setup

  • Provide a power supply within the desired voltage range (2.5V to 5.5V).
  • There is no need for an external crystal because it features an integrated temperature-compensated RC time base.

Event Monitoring

  • To monitor events and track active time, connect the event source to the EVENT pin.

Time Tracking:

  • A 32-bit nonvolatile counter is used to record elapsed time with quarter-second resolution.

Event Counting

  • It also uses a 17-bit nonvolatile event counter to count the overall number of occurrences.

Alarm Function

  • Configure the alarm output to send alerts when the cumulative time reaches a certain threshold.

Data Storage and Security

  • EEPROM user memory of 10 bytes for data storage.
  • For data security, a write disable method is included.


  • For data retrieval and programming, 2-wire serial communication is supported.


  • Time-of-use tracking, warranty monitoring, calibration, repair, and maintenance are all examples of applications.
