The DS17887-5+ is a high-performance, integrated real-time clock/calendar (RTC) with an embedded crystal and SRAM from Maxim Integrated. Designed for applications requiring precise timekeeping and data retention without an external power source, this device is a reliable solution for a wide range of applications, including embedded systems, servers, and industrial equipment.

With its built-in power-sense circuit, the DS17887-5+ monitors VCC for an out-of-tolerance condition. When an out-of-tolerance condition is detected, the device automatically switches to its backup energy source, ensuring that timekeeping and SRAM operations continue uninterrupted. This feature is crucial for maintaining data integrity and accurate timekeeping in the event of a main power failure.

The DS17887-5+ offers a multitude of features that make it a versatile component for any time-sensitive application. It includes a programmable alarm, interrupt function, and a programmable square-wave output, providing designers with flexibility in system design. The alarm can be set to a specific time or date, allowing for scheduled events or periodic system wake-ups.

Additionally, the device's 114 bytes of user-accessible, nonvolatile SRAM offer the ability to store critical data that must be preserved during power loss. This makes the DS17887-5+ an ideal choice for systems that require fault-tolerant data storage without the need for an external battery.

Communication with the DS17887-5+ is achieved through a simple multiplexed byte-wide interface, which allows for easy integration into existing designs. The device is fully Y2K-compliant and supports leap year compensation up to the year 2100, ensuring long-term usability without the need for firmware updates or modifications.

Encased in a 24-pin EDIP or SOIC package, the DS17887-5+ is designed for durability and ease of mounting on a variety of PCB layouts. Maxim Integrated's commitment to quality ensures that this RTC module delivers consistent performance and reliability, making it a trusted choice for engineers and designers around the world.
