Maxim Integrated DS1314E+T&R Nonvolatile Timekeeping RAM

The DS1314E+T&R from Maxim Integrated is a state-of-the-art nonvolatile timekeeping RAM that combines the functionality of a real-time clock (RTC) with a fully integrated NV (nonvolatile) SRAM and a sophisticated power-monitoring and control circuitry. This unique combination ensures that timekeeping and data storage are maintained even when the primary power source fails, making it an ideal choice for a wide range of applications including industrial control systems, telecommunications, and embedded computing.

The DS1314E+T&R features a built-in, long-life lithium battery that automatically switches on to maintain the RTC and SRAM data when the main power supply drops below a certain threshold. This seamless transition to the backup power ensures that the data integrity and timekeeping functions are preserved without interruption. The device also includes an automatic write-protection feature, which prevents data corruption during power loss.

The real-time clock in the DS1314E+T&R provides full calendar functionality with seconds, minutes, hours, day, date, month, and year information, and includes leap-year compensation valid up to the year 2100. The clock format can be set to either 24-hour or 12-hour with an AM/PM indicator, catering to different user preferences and international standards.

With a surface-mount package, the DS1314E+T&R is designed for easy integration into modern PCB designs. The device comes in tape and reel packaging (denoted by the T&R suffix), which is suitable for automated assembly processes, thus reducing manufacturing time and cost.

Maxim Integrated's commitment to reliability and quality is evident in the DS1314E+T&R, making it a dependable choice for maintaining accurate time and data retention across a variety of mission-critical systems. Its robust feature set and compact form factor make it an excellent choice for designers looking to enhance their system's reliability with minimal power consumption and space requirements.

Overall, the DS1314E+T&R is a versatile and reliable component that offers the assurance of uninterrupted timekeeping and data preservation, ensuring system integrity and performance even in the event of unexpected power disruptions.
