The DS1284QN is a real-time clock (RTC) integrated circuit with a battery backup that is specifically designed for use in microprocessor based systems.It is a small package solution that provides all of the functions associated with a traditional RTC in a limited number of components. The DS1284QN can be used in various applications, from medical instruments to consumer and industrial equipment.It provides a variety of features which make it a great choice for timekeeping applications. These features include battery backup, easy interface to a microprocessor system, accurate time keeping and year/month/day input, and integrated circuitry to help manage power consumption.The DS1284QN has an integrated crystal oscillator and an integrated battery backup circuit. The built-in crystal oscillator produces a high accuracy and high resolution clock that is calibrated using an external quartz crystal.The battery backup circuit ensures that the RTC’s memory registers and oscillator remain powered even when the main power supply is disconnected. The integrated circuitry also provides power and time management features such as power up event control, time stamping and time-out monitoring.The DS1284QN has an 8-bit microcontroller interface which allows it to be easily integrated into a system. This interface makes it possible to upload and download data and program the RTC without the need for additional components.In addition, the DS1284QN also provides a variety of flag and interrupt outputs which enable it to be used as a low-power interrupt controller. These outputs are triggered by the internal oscillator and can be used to initiate a response in an application.The DS1284QN is an ideal real-time clock solution for applications that require a robust, low-power and accurate timekeeping. It is highly integrated with a low component count and can be easily adapted to different timekeeping applications with minimal effort. Thanks to its integrated features and versatile interface, the DS1284QN is a great choice for embedded system design and timekeeping applications.
