DS1691 OverviewThe package 28-DIP Module (0.600, 15.24mm) contains real time clocks.The package is in the form of Tube.This electrical RTC has a supply voltage of 2.7V~3.3V 4.5V~5.5V.This electrical real time clock has the type Clock/Calendar.Through Hole is the way this real time clock (RTC) is mounted.Electronic time clocks are recommended that the operating temperature be 0°C~70°C.When operating, Alarm, Leap Year, Square Wave Output, Unique ID can be ensured.It is possible to terminate a transmission line with a RTC module that matches the characteristic impedance of the line, which is known as 28 termination.Obviously, a voltage of 3V is being supplied to this electronic component.There are 28 pins on it.For storing data and programs, the RTC times embed a memory of 114B.Real time clocks' output frequency should not exceed 0.032MHz.Upon receiving an input signal, 1 timers output a signal at a preset time.CAN ALSO OPERATE WITH 5V SUPPLY are also characteristics of it.A 16 bit digital time clock is designed for this application.
