The DS12885Q is a real-time clock/calendar circuit designed by Dallas Semiconductor that guarantees accurate time/date information. The device is perfect for a variety of applications which require nearly effortless operation — including internet servers, renewable energy sources, and industrial automation systems.

The core of the DS12885Q is a fully integrated real-time clock/calendar chip. This clock chip allows for accurately determined time and date — updating its calendar and clock values every second. The chip includes three 8 bit registers for day, hour and year and three 4 bit registers for month and day of the month.

The DS12885Q\'s timekeeping accuracy is provided by its built-in three-stage frequency-selector crystal oscillator. This accurately divides a 32.768 kHz signal into 1 second intervals and can be adjusted to be within required accuracy range depending on the application.

The DS12885Q has a variety of features designed to facilitate its use in a range of applications, including an internal low battery monitor, a trickle-charge circuit to enable long-term operation, an external clock-related interrupt, and two-year and four-year leap-year correction. The device\'s low power mode reduces current consumption to 0.1uA and wake-up time to under 400ms.

The DS12885Q is the ideal solution for applications which require accurate timekeeping with minimal power consumption. With its robust design and comprehensive features, this real-time clock/calendar chip makes for a reliable and effective addition to any time-sensitive system.
