Maxim Integrated DS1315EN-33/T&R Phantom Time Chip

The DS1315EN-33/T&R from Maxim Integrated is a highly sophisticated nonvolatile timekeeping chip, also known as the Phantom Time Chip, that is engineered to maintain accurate time and date information. This innovative component is designed for applications that require long-term, reliable timekeeping, even in the absence of power. It is an ideal solution for systems that cannot afford to lose temporal data and require a seamless transition back to normal operation after power restoration.

The DS1315EN-33/T&R operates with a nominal power supply voltage of 3.3V and is available in a tape and reel packaging, indicated by the T&R suffix, which makes it suitable for automated assembly processes. The chip's unique Phantom Time feature allows it to seamlessly switch to a backup energy source, such as a battery or a supercapacitor, to maintain timekeeping operations when the primary power supply is interrupted.

This timekeeping chip comes with a built-in trickle charger that ensures the backup energy source remains charged, thus extending the life of the backup power and reducing maintenance concerns. The device is equipped with a serial interface that simplifies integration into microprocessor-based systems, allowing for easy reading and setting of time and date information.

The DS1315EN-33/T&R is designed with a full calendar clock that includes seconds, minutes, hours, day, date, month, and year with leap-year compensation up to the year 2100. This level of precision ensures that systems relying on this chip for timekeeping will continue to operate accurately over an extended period.

With its robust feature set and high reliability, the Maxim Integrated DS1315EN-33/T&R is an excellent choice for a wide range of applications, including data logging, industrial controllers, security systems, and other embedded systems that require accurate timekeeping over long periods. Its compact design and ease of integration make it a versatile and indispensable component for maintaining system integrity where time is of the essence.
