The Maxim Integrated DS1384FP is a full-featured, microprocessor-compatible real-time clock with an integrated power-sense circuit. Designed to address the needs of complex systems, the DS1384FP incorporates a wealth of features for timekeeping, alarm functions, and system watchdog safety mechanisms, making it an ideal choice for a broad range of applications such as networking, telecommunications, and embedded systems.

This versatile timekeeping IC includes a real-time clock/calendar and 256 bytes of static RAM. It communicates with a microprocessor via a simple serial interface. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator.

A programmable alarm and interrupt function allows the DS1384FP to be configured for a variety of tasks. The alarm can be set to a specific moment or to repeat daily, giving designers flexibility to implement the functionality needed for their specific use cases. Additionally, the device features a watchdog timer that can be programmed to reset the system in case of a software lock-up, enhancing system reliability.

The DS1384FP also includes a power-sense circuit that detects power failures and automatically switches to a backup supply, ensuring continued timekeeping and memory retention. This feature is critical for maintaining data integrity and system functionality in the event of power interruptions.

Encased in a power-saving, space-efficient package, the DS1384FP is designed for systems where space is at a premium but full functionality is required. Maxim Integrated's commitment to quality ensures that the DS1384FP meets the stringent requirements of industrial applications, providing a robust and reliable timekeeping solution that system designers can trust.
