The DS17285SN-5 is a highly integrated real-time clock (RTC) module from Maxim Integrated, designed to provide a comprehensive timekeeping solution for a wide range of applications. This RTC is a full-function, year 2000-compliant (Y2K) timekeeping device that includes a built-in crystal and SRAM. It is specifically tailored for systems that require an accurate time and date reference, such as servers, telecommunications, data loggers, and embedded systems.

The device features a serial interface that is compatible with the industry-standard SPI protocol, allowing for easy integration into existing designs. Its 5V power supply voltage makes it suitable for many digital systems without the need for additional voltage regulation. The DS17285SN-5 also includes an automatic backup battery switch-over circuitry, ensuring that timekeeping continues uninterrupted during power failures when used with an external battery.

In addition to timekeeping, this RTC module offers a variety of functions that enhance its utility. These include two time-of-day alarms, a programmable square-wave output, and a watchdog timer. The device also has a power-fail write-protect feature for its SRAM, which helps to preserve critical data during power loss events.

The DS17285SN-5 is packaged in a 24-pin (300-mil) SOIC, providing a compact footprint suitable for space-constrained applications. Maxim Integrated's commitment to quality ensures that this RTC module delivers reliable performance and long-term durability, making it a trusted component for your time-sensitive projects.

Whether you're designing industrial control systems, consumer electronics, or any other time-dependent application, the DS17285SN-5 Real-Time Clock from Maxim Integrated is an excellent choice for maintaining accurate time and date information.
