The Maxim Integrated DS17885-3+ is a highly integrated real-time clock (RTC) module that offers a comprehensive timekeeping solution for a wide array of applications. This RTC is designed to provide precise time and date information, including seconds, minutes, hours, day, date, month, and year, with leap-year compensation up to the year 2100.

Featuring a built-in crystal oscillator and a battery input, the DS17885-3+ maintains accurate timekeeping even when the main power is lost, making it ideal for systems that require an always-on timekeeping component. The device is equipped with a serial interface that allows easy communication with microcontrollers or microprocessors, ensuring seamless integration into existing systems.

Key Features:

• Integrated temperature-compensated crystal oscillator (TCXO) for high precision
• Automatic power-fail detect and switch circuitry
• Programmable alarm and interrupt functions for versatile use cases
• Binary-coded decimal (BCD) or binary time representation for flexibility
• Low power consumption, suitable for battery-backed applications
• 128 bytes of NV SRAM for data storage

The DS17885-3+ also includes additional features that enhance its functionality, such as a programmable square-wave output, which can be used for timing or as a watchdog timer. The device's 128 bytes of non-volatile (NV) static RAM allow for the storage of data or configuration settings that need to be preserved during power loss.

With its robust design and extended temperature range, the DS17885-3+ is well-suited for industrial applications, telecommunications, embedded systems, and any other systems that require reliable timekeeping under varying conditions.

Maxim Integrated's commitment to quality ensures that the DS17885-3+ meets the stringent requirements of the most demanding applications, providing a reliable and long-lasting timekeeping solution for your product designs.
