DS1643-100 Overview
In the 28-DIP Module (0.600, 15.24mm) package, real time clocks is embedded as a dependency.Tube is the package format.There is 4.5V~5.5V supply voltage for this electrical RTC.The electrical real time clock belongs to the type Clock/Calendar.On the system board, this real time clock (RTC) is mounted in Through Hole.0°C~70°C should be the operating temperature.When running a program, electronic time clocks may be possible to ensure that Leap Year, NVSRAM are maintained at all times.With 28 terminations, transmission lines have the characteristic impedance of the RTC module terminating them.In this RTC real time clock, there is a voltage of 5V supplied to it.A total of 28 pins are attached to this RTCs.In the family DS1643, RTCs are a member.There are such RTCs in Timer or RTC subcategory.For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 8KB.Mounting type for the RTC module is Through Hole.It operates from 5V power supplies.A total of 28 pins are equipped with the real time clock.There are 1 timers, which are control real time clocks that output a signal at a preset time after an input signal is received.A high efficiency supply voltage should be maintained at 5V.32.8kHz is the maximum frequency that can be achieved.
