The DS17285 is a real-time clock module particularly suited for industrial, telecommunications and data-processing applications. This integrated circuit contains a 32768 kHz crystal oscillator, a control/timing unit, and a number of counters for managing time and date. The external crystal provides an accuracy of ±3 minutes a year, but the accuracy can be increased by external temperature compensation. The combination of two versions of this clock, i.e. the DS17285SN-5+ and the DS17285SN-6+, offers great flexibility in managing and monitoring time and date.

The DS17285SN-5+ is the simplest version of the DS17285 family and provides one-second accuracy and up to eight alarms capabilities. The DS17285SN-5+ is designed to provide real-time clock capabilities with minimum parts count. This version is suitable for many applications such as industrial, telecommunications, data processing and automotive applications.

In terms of applications, the DS17285SN-5+ real-time clock module is mainly used to monitor time and date. It can be used to synchronize multiple systems in order to ensure quick response to triggers or events such as alarms or events in an industrial environment. It is also suitable for applications such as synchronizing communication systems for reliable data transmission and protecting critical data stored in memory against integrity problems.

In addition to that, the DS17285SN-5+ can be used to control power down and up functions. This clock module can also be used for keeping system clocks up-to-date in the event of a power outage or system reset. Moreover, the clock module can be used in embedded systems, offering maximum reliability and accuracy for the management of time and date.

The DS17285SN-5+ real-time clock module works on the basis of a 32768 kHz quartz crystal oscillator and a control/timing circuit. This oscillator provides a frequency accurate to within ±3 minutes a year, but it can be improved using an external temperature compensation circuit. The control/timing circuit then manages the accuracy of the time and date signals and ensures they are maintained even when there is an unexpected reset.

By combining the external crystal and the control/timing unit, the DS17285SN-5+ real-time clock module provides up to eight alarm capabilities which can be set to trigger at any time. This alarm can be used to trigger specific functions such as a power down, system reset or data refresh.

The DS17285SN-5+ is an advanced real-time clock module capable of accurately monitoring time and date with minimum parts count and without external temperature compensation. It is suitable for use in industrial, telecommunications, data processing and automotive applications, and offers flexibility and reliability in managing and monitoring time and date.
