DS1644-120 Overview
There is a package 28-DIP Module (0.600, 15.24mm) that contains real time clocks.A Tube package is used to package time clock.This electrical RTC has a supply voltage of 4.5V~5.5V.This electrical real time clock is type Clock/Calendar.A part of this electronic RTC module is mounted in the way of Through Hole.The operating temperature should be 0°C~70°C.When operating, electronic time clocks are possible to ensure that Leap Year, NVSRAM are maintained.The 28 termination is the practice of terminating a transmission line with a RTC module matched to its characteristic impedance.This RTC real time clock is powered by 5V volts.28 pins are attached to it.RTCs belongs to DS1644 family.It falls under the subcategory of Timer or RTC.For storing data and programs, the RTC times embed a memory of 32KB.RTC module mounting type Through Hole is specified.For powering the real time clock, a power supply with a voltage of 5V is used.There are 28 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock. Optimal efficiency requires a supply voltage of 5V.
