DS1244WP-120 Real Time Clocks Overview

The DS1244WP-120 is a real-time clock developed by the extensive research and development department at Dallas Semiconductor. The DS1244WP-120 offers a number of features that make it an ideal choice for a wide variety of applications. The DS1244WP-120 is a battery backed-up and temperature compensated non-volatile SRAM that is designed to keep time and date information in the event of a power interruption. Due to its low power consumption, it can be used in virtually any application needing accurate timekeeping, regardless of the amount of power fluctuation or ambient temperature.

Features of the DS1244WP-120

The DS1244WP-120 offers a wide range of features which make it an ideal RTC choice. It has a temperature compensated which makes it very accurate, even in changing temperature environments. Additionally, the clock runs on a low voltage of 2.4 V to 5.5 V, making it compatible with most systems. The clock also has several modes: Normal operation, Standard Interrupt Mode and Battery Charger Mode. In Normal Operation, the clock keeps time and date in the event of a power fail. In Standard Interrupt Mode, a 12-hour interrupt can be programmed to occur at any time-slot. Lastly, in Battery Charger Mode, the clock will monitor the voltage level of the battery and turn off when the battery has been fully charged. It also has a 31 day/year calendar which is capable of keeping track of up to 16 years. This makes the DS1244WP-120 an ideal choice for applications where extensive time tracking is needed, such as databases and other applications that need to keep track of large amounts of data.

Application Fields for the DS1244WP-120

Due to its low power consumption and accuracy, the DS1244WP-120 is a popular choice for a variety of applications. Examples include medical equipment, embedded controllers, remote data acquisition systems and so on. In medical applications, the DS1244WP-120 is ideal for accurate and reliable tracking of medical records, such as patient vital signs, appointment scheduling, etc. In embedded controllers, it is used for accurate timing of system events, such as automated power on and shutdown, etc. In remote data acquisition systems, it is perfect for measuring and tracking data collected from its sensors in an accurate and reliable way.

Working Principle of the DS1244WP-120

The DS1244WP-120 is based on an oscillator, voltage stabilizer and auto battery charger. It uses an oscillator to generate a timebase that is used to measure the time that has passed and to calculate the current date and time. The voltage stabilizer ensures that the clock is running in a stable voltage level, regardless of power fluctuations. Finally, the auto battery charger constantly monitors and adjusts the battery\'s voltage level to maintain its optimal performance. The clock also utilizes a calendar circuit to keep track of dates, with the option of setting up to 16 years of data storage. Then, with the help of a low power static RAM, the clock stores all its information. Every time the clock is powered on, it reads the data from the static RAM and displays and displays the current date and time.

Conclusion

The DS1244WP-120 is a popular real-time clock that is designed to keep time and date in the event of a power interruption. It has a low power consumption and is temperature compensated, making it an ideal choice for a wide variety of applications. In addition, it can store up to 16 years of data, features multiple modes and uses a calendar circuit to keep track of dates.
