DS1286+

The DS1286+ Real Time Clock (RTC) is a highly accurate timing circuit designed for use in industrial, commercial and consumer applications. It provides an accurate timekeeping function in applications such as computers, security systems, medical systems, and radio communications equipment. The DS1286+ offers low power consumption in a tiny 8-pin package.

The DS1286+ provides a wide variety of timing options, including: programmable alarm settings, selectable time zone, daylight savings options and input/output pins for connection to external devices. It also includes an integrated microphone, LCD display and watch alarms. The integrated calibration circuit allows for a more accurate timekeeping than traditional RTCs, providing accuracy of ± 2ppm over temperature.

The DS1286+ also features an alarm detect feature that wakes up the processor when an alarm event occurs. This is useful in battery-powered systems where power consumption must be minimized to maximize system lifetime. The DS1286+ has been designed to provide a highly accurate and reliable timing solution, and can be used in many different applications.

The DS1286+ Real Time Clock works by counting the number of cycles of an oscillator, usually a quartz crystal, and incrementing an internal counter each time. The counter is then converted to a date/time format, and can be used to control various functions such as controlling system shutdown or program execution. The accuracy of the clock depends on the frequency of the oscillator used, as well as the accuracy of the counter circuitry. Typical accuracy is within ±1 second a day, over a wide temperature range.

The DS1286+ is a low power device and uses very little energy compared to other real-time clocks. This is achieved by using an extremely low power oscillator and an advanced multiplexed counter design. This makes the DS1286+ ideal for battery-powered or portable devices, and ensures that the device will remain accurate even during extended periods of low power. The DS1286+ can also be connected to an external battery, providing timekeeping during power outages.

The DS1286+ is an ideal solution for any application where accuracy and reliability of a real-time clock are required. By providing extremely accurate timing and low power consumption, the DS1286+ is well suited for a variety of industrial, commercial and consumer applications, including: medical systems, security systems, communications equipment, computer systems and embedded systems.
