DS1646-120 Overview
In the 32-DIP Module (0.600, 15.24mm) package, real time clocks is embedded as a dependency.The package is Tube.4.5V~5.5V is the supply voltage of this electrical RTC.The type of this electrical real time clock is Clock/Calendar.real time clock (RTC)s like this are mounted in the way of Through Hole.In order to be safe, electronic time clocks are imperative that the temperature are kept at 0°C~70°C at all times.When operating, Leap Year, NVSRAM can be ensured.With 32 terminations, transmission lines have the characteristic impedance of the RTC module terminating them.Obviously, a voltage of 5V is being supplied to this electronic component.A total of 32 pins can be found on it.RTCs belongs to DS1646 family.This electrical digital time clock has a supply voltage of 3V.A real time analog clock's memory size is 128KB, which is available for storing programs and data.The frequency of real time clocks' output should not exceed 0.032MHz.
