DS1644-120+ Overview
You can find real time clocks in package 28-DIP Module (0.600, 15.24mm) among the other packages that are available.Packaged as Tube.It is important to keep in mind that the supply voltage of this electrical RTC is 4.5V~5.5V.The electrical real time clock belongs to the type Clock/Calendar.In this case, Through Hole is the way this part is mounted on the systemboard.0°C~70°C should be the operating temperature.When operating as part of a process, electronic time clocks are possible to ensure that Leap Year, NVSRAM are maintained at all times.It is possible to terminate transmission lines with 28 terminations, which means that the RTC module terminating the line matches its characteristic impedance.This electronic component receives a voltage of 5V.A total of 28 pins are included in this product.There are only one family in which RTCs belongs, and that are DS1644.Located in Timer or RTC, this component is present.In these RTC times, there is a memory of 32KB where data and programs can be stored.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.
