Real-time clocks are electronic circuits that provide us with accurate time and date information. The DS1386-32-120+ is a real-time clock module which provides the time and date information in digital form, making it ideal for applications that require synchronization with a time source.

Overview

The DS1386-32-120+ is a low-cost real-time clock module from Dallas Semiconductor Corporation. It is designed for providing date and time information for small embedded systems, such as those found in consumer electronics, robotic applications, and in telecommunication networks. This device features leakage-proof battery backup, which makes it immune to brownout events.

Application Fields

The DS1386-32-120+ is ideal for applications that require synchronization with a time source. One of the most common applications is in industrial automation, where the real-time clock is used to synchronize the steps of various machines. It can also be used in medical devices, where patient records can be timestamped to ensure accuracy and proper record keeping.

The DS1386-32-120+ is also well-suited to automotive diagnostic systems, where it can be used to provide partial or full synchronization between devices. It is also useful in security systems, where it can be used to trigger alarms at specific times, or to monitor access times. Additionally, it can be integrated into systems used for tracking vehicle locations, such as those used for fleet management systems.

Working Principle

The DS1386-32-120+ real-time clock modules use an oscillator to generate an accurate clock signal. This signal is used to drive a set of counters, which in turn provide the time and date information. The frequency at which the oscillator operates is maintained by a pair of timing capacitors, which create a frequency-dependent voltage. This voltage is then regulated by a temperature-compensated bandgap reference circuit, which helps ensure accuracy.

The DS1386-32-120+ uses an integrated battery backup system to maintain the time information. In the event of a blackout or other power interruptions, the system will keep running on the battery until the power is restored. This makes the system highly reliable and perfect for applications that require an always-on clock.

Conclusion

The DS1386-32-120+ is a low-cost, accurate, and reliable real-time clock module. It is designed for use in small embedded systems, and can be used in applications that require synchronization with a time source. It features an integrated battery backup system, which ensures that time information is retained even during a power failure. By taking advantage of the DS1386-32-120+, you can ensure that your systems have the most up-to-date time and date information available.
