The DS12885N from Maxim Integrated is a versatile, high-performance real-time clock (RTC) IC that provides a comprehensive timekeeping solution for a wide array of applications. This integrated circuit maintains seconds, minutes, hours, day, date, month, and year information, with automatic adjustments for leap years up until the year 2100.
One of the standout features of the DS12885N is its dual power supply pins, which allow the device to be powered from a primary 5V supply and a backup source to ensure uninterrupted operation should the main power fail. This makes it a reliable choice for systems where maintaining accurate time is crucial, even in the event of power interruptions.
The device incorporates a serial interface that supports both the Intel and Motorola bus types, making it flexible for integration with a variety of microprocessors. It also includes a battery-backed nonvolatile (NV) RAM, which provides 114 bytes of storage that can be used to store system configuration or calibration data that must be preserved when power is not available.
Additional features of the DS12885N include programmable alarm and interrupt functions that can be set to trigger on a specific second, minute, hour, day, or date, providing a useful tool for scheduling routine tasks or reminders. The clock operates in either 24-hour or 12-hour format with an AM/PM indicator, catering to different time-keeping preferences.
Encased in a 24-pin EDIP (Extended Dual In-line Package), the DS12885N is designed for easy integration into PCB layouts. Its robust design and wide operating temperature range make it suitable for industrial environments and demanding applications. This RTC is a reliable component for embedded systems, data loggers, communication equipment, and any other system where accurate timekeeping is paramount.
Maxim Integrated's commitment to quality ensures that the DS12885N RTC meets the highest standards for performance and reliability, making it a preferred choice for designers and engineers looking for a trusted timekeeping solution.
