DS1315N-5 is a real-time clock (RTC) featured by Maxim-Dallas Semiconductor. The DS1315N-5 provides a clock and calendar that acknowledge the leap year and offer full range up to 2100 year. The clock and calendar work in binary coded decimal (BCD) format with integrated crystal oscillator. There are several features such as battery-switchover, square-wave output, alarm provide that make this chip a suitable choice for wide range of applications.

The DS1315N-5 can be used for various timing and clock applications for either intermittent or continuous operations. Having a wide range of operating temperature from -40C to 85C and Operating Voltage range from 1.4V to 5.5V makes this chip suitable for many of the applications. Timer alarm is generated when selected registers match with real-time clock. The user can select from 3 modes (year, month and day). Additionally, it supports a time-out mode where the timer will stop after reaching a pre-defined limit.

The DS1315N-5 contains two internal oscillators. A 32.768kHz quartz crystal oscillator is used to provide an extremely accurate and stable time-base. It also has an internal oscillator which can be used if external oscillator is not available. It does not require any additional components for external operation and has bonus Free-Run operation for uninterrupted timing whether or not the power is available.

The device includes several features such as a low-power logic control and low current-consumption that can reduce system power consumption. The logic control supplies power directly to the the oscillator ensuring the chip\'s stability and accuracy. The included RAM bank allows user to store multiple registers that enable user to write, read and clear them.

The DS1315N-5 is designed to provide seamless operation as well as long term reliability. It is available in five packages (QFP, SSOP, TSSOP, SOIC, and LQFP) and supports an operating temperature range of -40C to 85C. The chip has several programming options including four-year centennial, leap year, hourly time format, and daylight savings time.

In summary, DS1315N-5 is a real-time clock (RTC) with a variety of features that make it suitable for a wide range of applications. It has a low-power logic control and low current consumption which helps reduce system power consumption. The device includes features like time-out mode, battery-switchover, clock and calendar and RAM bank which makes it a perfect choice for timing and clock applications.
