The DS17887-3+ from Maxim Integrated is a highly integrated, full-featured Real-Time Clock (RTC) module that offers a comprehensive timekeeping solution for a wide array of applications. This RTC integrates a quartz crystal and a lithium battery into a monolithic, surface-mountable, encapsulated package, ensuring long-term reliability and high precision in timekeeping.

One of the standout features of the DS17887-3+ is its compliance with the industry-standard DS12887, providing a drop-in replacement for systems that require an upgrade or a direct replacement. The device includes a built-in power-sense circuit that detects power failures and automatically switches to the battery supply, maintaining time and date operation when main power is lost.

Key Features:

• Integrated Power-Supply: The RTC comes with an embedded battery, which ensures a long life span and consistent performance, even during power outages.
• High Precision: The onboard crystal oscillator provides high stability and accuracy for timekeeping, making it an ideal choice for critical applications.
• Automatic Power-Fail Detect: The DS17887-3+ has a built-in feature that switches to battery backup during voltage drops or failures, preserving data integrity.
• User-Accessible Memory: It includes 114 bytes of user-accessible NV RAM, allowing additional data storage that is not affected by system power cycles.
• Multi-Function Alarms: The device supports periodic or single alarms, enabling users to set up multiple time-based events.
• Extended Temperature Range: This RTC operates efficiently across a wide temperature range, suitable for various environmental conditions.
• Compatibility: It offers plug-and-play compatibility with the DS12887, simplifying the upgrade process for existing systems.

The DS17887-3+ is an exemplary choice for applications that require accurate timekeeping, such as embedded systems, utility meters, POS terminals, and industrial controllers. Its robust feature set ensures that it can meet the demands of even the most time-sensitive applications.

With Maxim Integrated's commitment to quality and reliability, the DS17887-3+ is designed to deliver consistent performance and ease of integration, making it a top choice for designers and engineers seeking a reliable RTC solution.
