DS1643-85+ Overview


In package 28-DIP Module (0.600, 15.24mm), real time clocks is located.Tube is the way in which time clock is packaged.Unless otherwise stated, this electrical RTC's supply voltage is 4.5V~5.5V.The type of this electrical real time clock is Clock/Calendar.On the system board, this real time clock (RTC) is mounted in Through Hole.A safe operation requires a temperature of 0°C~70°C at all times.When a command are executed, electronic time clocks are possible to maintain Leap Year, NVSRAM in order to maintain the current state.It is possible to terminate a transmission line with a RTC module that matches the characteristic impedance of the line, which is known as 34 termination.5V is the supply voltage of this RTC real time clock.The RTCs are equipped with the necessary features due to its 34 pins.DS1643 are RTC s family.Programs and data can be stored in the 8KB memory embedded in the RTC times.It should not exceed 0.032MHz as the output frequency of the real time analog clock.This RTC module is mounted using type Through Hole.A total of 28 pins are equipped with the real time clock.RTC time is essential that the supply voltage remain at 5V for maximum efficiency.
