Maxim Integrated DS1315E-5+ Phantom Time Chip

The DS1315E-5+ from Maxim Integrated is a highly sophisticated, nonvolatile timekeeping chip, also known as the Phantom Time Chip. This innovative component is designed to provide a full-featured real-time clock/calendar and 31 bytes of static random access memory (SRAM). Engineered to maintain timekeeping functionalities even when the primary power supply is turned off, the DS1315E-5+ ensures that timekeeping operations continue uninterrupted by automatically switching to a backup energy source.

The DS1315E-5+ operates in a wide voltage range from 2V to 5.5V, making it versatile for various applications. Its timekeeping functions include seconds, minutes, hours, day, date, month, and year information, with the added capability of automatic leap year correction up to the year 2100. The device also features a trickle-charge capability, which allows a rechargeable energy source to be used for backup power, ensuring long-term reliability and accuracy of the timekeeping functions.

Encapsulated in a compact, surface-mount 20-pin (300-mil) SO package, the DS1315E-5+ is designed for easy integration into a broad range of applications, including embedded systems, utility meters, industrial equipment, and other devices that require accurate time and date management. The chip's communication with a microprocessor is facilitated through a simple serial interface, which is compatible with most microcontrollers.

Key features of the DS1315E-5+ include:

• Nonvolatile timekeeping with 31 bytes of NV SRAM
• Automatic switch to backup supply during power failure
• Trickle-charge capability for backup energy sources
• Simple serial interface for easy communication
• Automatic leap year correction
• Compact SO package for space-constrained applications

Maxim Integrated's commitment to high-quality and reliable integrated circuits is reflected in the DS1315E-5+ Phantom Time Chip. This product is an excellent choice for designers who need a dependable timekeeping solution that will maintain accuracy and functionality even in the event of a primary power loss.
