The DS1643P-85+ is a real-time clock (RTC) with a 3V backup battery, designed to provide access to the long-term accurate timekeeping. This device utilizes an oscillator of 32.768 kHz for accurate timekeeping regardless of any other clock source, making it an ideal choice in battery powered applications since it allows the circuit clock to remain untouched in the current state. The DS1643P-85+ is a timekeeping device with a battery backup that can provide time accurately, even if the power is off.

The DS1643P-85+ is designed to be used in a wide variety of battery powered applications such as healthcare and medical instruments, automotive electronic control modules, automated test systems, and data loggers. This RTC can be used in various applications in low-power to high-power requirements. It is also an ideal choice for applications in environments where power may be unavailable.

The DS1643P-85+ provides access to a wide range of timekeeping related data, like time and date, time zone, calendar and leap years. It is highly accurate, with a timing accuracy of 10 seconds per year, and it also offers self-disciplining timekeeping and automatic time adjust mechanisms. The DS1643P-85+ offers a self-adjusting timekeeping mechanism to compensate for the frequency offsets caused by temperature changes and ambient noise.

The DS1643P-85+ is also guaranteed to stay in sync with its parent oscillator, regardless of the power source or external environment. The integrated 32 kHz oscillator is also designed to be very resistant to mutation, with a stability of 20ppm/degree Celsius. The device is also designed to be robust, with a Shock and Vibration Survival rating of up to 20g and 1,000Hz respectively.

The DS1643P-85+ utilizes a variety of technologies to allow accurate date and timekeeping. Its primary source of accurate timekeeping is from the integrated 32.768 kHz oscillator, which is provided power by a 3V backup battery. When powered and connected to an external clock, this device can synchronize its clock to the external clock sources and adjust its time accordingly.

Additionally, the DS1643P-85+ includes integrated voltage and temperature monitoring, to allow further power and environment monitoring. The integrated voltage monitoring allows the device to be shut down in the case of low voltage, to prevent further damage. The integrated temperature monitor also allows the device to shutdown if the temperature exceeds a preset value.

In summary, the DS1643P-85+ is an ideal choice for a variety of battery-powered, clock/timing applications, with its integrated high accuracy timekeeping, voltage and temperature monitoring, self-adjusting timekeeping, and robust environment resistance. The device can be powered using a 3V backup battery, or an external clock for synchronization. This makes it the perfect choice for a wide variety of applications, from healthcare, automotive, test systems and data loggers.
