Introduction to DS17287-5+

DS17287-5+ is a real-time clock (RTC) designed as an industrial-grade product used in industries, commercial applications, and home applications. It is widely used as an embedded timepiece to serve applications ranging from system time tracking, security, and automation. The RTC has many features designed to make it applicable to most digital electronic systems without the need to make alteration such as time setting and alarm setting. The DS17287-5+ is an excellent choice for industrial and home applications due to its robust design and feature set.

Features and Benefits of DS17287-5+

The DS17287-5+ is a high-performance real-time clock offering great features and benefits. It has a large battery back-up capability, a 6-bit binary-coded decimal (BCD) format for clock setting, and a 50-Year Calendar Format. The battery-backup is nominally specified to run for up to 10 years with battery voltage from 1.2 to 3.6 volts DC. This guarantees reliability and consistency even in the case of a power failure. The BCD format also makes it possible to set the clock in seconds and determines if the time is correct. The 50-Year Calendar Format can be set to display month and date time even in leap years. The DS17287-5+ also offers an adjustable full-mask alarm, which can be set to alert the user of certain predetermined time of day. It also has a digitally controlled oscillator (DCO) which enables software power-saving while keeping accuracy at a maximum.

Applications of DS17287-5+

The DS17287-5+ is widely used in many applications and industries. It is commonly used in industrial and commercial applications including factory automation, access control systems and time scheduling. It is also used for home security systems and alarm systems. Moreover, the adjustable full-mask alarm feature makes the DS17287-5+ an excellent choice for time-based automatic activities such as load control, data logging, customized event programming, and run-once activities. The DS17287-5+ is also a reliable timekeeping device for embedded systems, microcontrollers and smart energy devices, such as thermostats or any other digital or embedded electronics.

Working Principle and Operation of DS17287-5+

The DS17287-5+ is an I²C real-time clock that operates on two-wire protocol, meaning it does not require a separate clock line. The RTC also contains an oscillator circuit, which is a quartz crystal clock and generates the pulses that are used by the device to accurately keep track of time. The quartz crystal oscillator circuit ensures a low-power, low-jitter, consistent time-keeping performance. The device can be easily connected to a power supply and configured to be used with a PC or embedded system.

The RTC contains an internal crystal to store and keep track of time and date. The timekeeping mechanism is based on perpetual calendar, meaning users do not have to worry about adjusting the calendar each year. The clock can be easily programmed using the 6-bit BCD format, and the full-mask alarm can be easily configured as well. The device can also be programmed to control power-down time and alert users at specified times, making it ideal for applications requiring time accuracy.

Conclusion

In conclusion, the DS17287-5+ is an excellent choice for industrial and commercial applications due to its robust design and useful features. It is a reliable timekeeping device for embedded systems, microcontrollers and smart energy devices. The large battery back-up capability, 6-bit binary-coded decimal (BCD) format for clock setting, adjustable full-mask alarm, and 50-Year Calendar Format also make the DS17287-5+ a popular choice for commercial applications. The device is also easy to configure and program ensuring time accuracy and reliability.
