Real Time Clocks (RTCs) have become an essential part a variety of electronic products and applications. These devices allow for time to be accurately measured, no matter the environment or application. One type of RTC, the DS1347T+T&R, is particularly notable due to its broad range of uses and low power consumption. Below, we’ll explore the DS1347T+T&R and discuss what makes it unique.

Overview of DS1347T+T&R

The DS1347T+T&R is a temperature compensated Real Time Clock (TCXO) with a maximum frequency of 45MHz. It features an optimized Small Form Factor (SFF) 8-pin package and is manufactured using a High Voltage Silicon on Insulator (HVSOI) process. This allows for the use of high frequency signals and improved performance in harsh conditions, such as extreme temperatures and radiation. The device is rated for an operating voltage of 1.8 to 5.5V DC and has a low current drain of 2.4mA at 5V DC.

The device has four distinct modes of operation: standby, weak wakeup, real time, and real time & calendar. Standby mode powers down the device when not in use, which reduces the power consumption to less than 2µA. Weak wakeup mode allows for a low-power transition from standby to real time operations, while real time mode enables time keeping duties. The real time and calendar mode allows for timing information as well as calendar related functions. This can include reading and setting of the hours, minutes, and seconds, as well as the day, month, and year.

Applications and Features

The DS1347T+T&R is an ideal solution for applications that require power optimization and precision timing. The device is ideal for use in battery operated products and is compliant with the RoHS directive, making it both environmentally friendly and cost effective. The small size and low profile makes it suitable for space constrained applications. Additionally, the device also has a “PWM mode”, enabling it to be used as a pulse width modulator to drive devices requiring specific frequencies, such as LEDs.

The adjustable output drives of the DS1347T+T&R make it suitable for use in industrial applications, such as factory and component automation. The versatility of the DS1347T+T&R makes it ideal for use in a wide range of products, including but not limited to: medical devices, smart meters, security systems, telecommunications systems, and more. These features also make the DS1347T+T&R a valuable component in precision radio frequency (RF) applications, used in everything from RADAR to Global Positioning Systems.

Working Principle

The working principle of the DS1347T+T&R is based on its power optimization features. One of the main features of the device is the automatic switch between Standby and Real Time modes. In Standby mode, the device powers down, reducing the power consumption to less than 2µA. The Weak Wakeup feature then allows for a low-power transition from Standby mode to Real Time mode. Once in Real Time mode, the device continues to track time, with the help of an external oscillator, and to carry out calendar related functions.

The device is also capable of measuring temperature and adjusting its output signal, if necessary. This ensures that the timing information provided by the device remains precise and stable, no matter the temperature or environment. This is especially important for applications in which precision timing is essential, such as those found in factory automation or medical technology.

Conclusion

Real Time Clocks, such as the DS1347T+T&R, provide an essential function in a variety of applications. The device has an impressive array of features, including low power consumption, a wide range of uses, and temperature compensation. Its versatility makes the DS1347T+T&R the ideal RTC for use in a wide range of applications, from industrial automation to medical technology. By understanding the features and the working principle of the DS1347T+T&R, one can better understand the importance of Real Time Clocks and the various applications in which they can be used.
