The DS12887+ is an integrated, full-featured real-time clock (RTC) module from Maxim Integrated, designed to provide an all-in-one solution for timekeeping in a wide range of computing applications. This RTC module is a direct replacement for the industry-standard DS12887 and is designed to be drop-in compatible with existing systems, making it an ideal choice for legacy equipment maintenance as well as new designs.

The DS12887+ integrates a quartz crystal and lithium battery into a 24-pin encapsulated DIP (Dual In-line Package), allowing it to maintain accurate time and date information for years in the absence of external power. The module offers a multitude of timekeeping features, including seconds, minutes, hours, day, date, month, and year counters with leap year compensation valid up to the year 2100.

In addition to basic timekeeping, the DS12887+ offers several advanced features:

• An interrupt controller with multiple interrupt modes, providing the flexibility to signal the host system for periodic or one-time events.
• A programmable square-wave output that can be used for timing, clocking, or as an alarm signal.
• A 114-byte, battery-backed, non-volatile RAM for storage of critical data that must be preserved during power loss.
• Automatic power-fail detection and switching circuitry that ensures the transition to battery backup is seamless in the event of a power outage.

With its built-in crystal and battery, the DS12887+ ensures a stable and reliable time base, making it an essential component in systems that require precise event logging, scheduling, or real-time data acquisition. Its robust feature set is particularly well-suited for use in embedded systems, industrial controllers, point-of-sale terminals, network hardware, and other applications where maintaining accurate time is crucial.

The DS12887+ is designed to operate over a wide temperature range, making it suitable for deployment in challenging environmental conditions. Maxim Integrated's commitment to quality ensures that the DS12887+ provides the reliability and performance expected of modern electronic components.
