The DS1486-120 is a real-time clock or calendar that allows for a user to set running time countdown alarms and also easily reset settings from a power loss incident. It is specifically designed for use in a variety of embedded electronic applications, including industrial and instrumentation settings, building automation systems and computers. For these purposes, the DS1486-120 can track real-time events with absolute accuracy up to 6 decimal places.When mounted to a printed circuit board, the DS1486-120 can regulate time and date settings without the help of software. This makes it ideal for use in industrial control systems, where precision and accuracy are of the utmost importance. The DS1486-120 is a low-power, cost-effective and reliable clock/calendar that accurately monitors time and date information, even in the event of any power-loss incidents. It has a 10-pF external load capacitor for accurate timing, and features a master-slave switch for monitoring two external events, such as sunrise or sunset. It also includes a resettable alarm and 7-day alarm counter. The real-time clock of the DS1486-120 includes an 8-bit timer-counter, as well as 7-day and 6-decimal-place counters for long-term precision event monitoring. The real-time clock operates on an internal 32.768 kHz quartz crystal oscillator and features an automatic frequency control (AFC) circuit for ensuring accuracy and stability of the timekeeping data. The DS1486-120 also has a programmable low voltage detection feature that can be used to shut off power to the system safely, in order to preserve system data and program settings.The DS1486-120 real-time clock is powered by a 3V lithium battery that lasts up to 10 years and is housed in an 8-pin DIP package. Its low power consumption and the long battery life make it ideal for use in a variety of applications. It also features a highly efficient, two-wire communication interface for I2C communications, allowing for easy integration with a host controller or system. In summary, the DS1486-120 is a reliable, accurate and low-power real-time clock designed for use in a variety of embedded electronic applications. It offers precision time information and reliable alarm and event monitoring, as well as a wide range of programmable features and a long battery life. The low power consumption and the easy integration with a host controller or system makes the DS1486-120 a cost-effective option for accurately monitoring time and date information.
