DS1689S+ Overview
A package named 28-SOIC (0.295, 7.50mm Width) contains real time clocks.Tube is the way time clock is packaged, which is the way time clock is intended to be.The supply voltage of this electrical RTC is 2.7V~3.3V 4.5V~5.5V.An electrical real time clock of type Clock/Calendar can be said to be this one.The position of this real time clock (RTC) on the system board is indicated by Surface Mount.There should be 0°C~70°C operating temperature.When operating, electronic time clocks would be possible to ensure that the value NVSRAM are maintained.With 28 terminations, transmission lines have the characteristic impedance of the RTC module terminating them.This RTC real time clock is supplied with 3V voltage.28 pins are attached to it.There are only one family in which RTCs belongs, and that are DS1689.This electrical digital time clock has a 2.5V~3.7V supply voltage.A component such as this is included in the contents of Timer or RTC.There is a memory size of 114B available for storing data and programs on the real time analog clocks.The output frequency of this real time analog clock should not exceed 0.032MHz Hz.In order for it to be powered, it requires a power supply of 3/5V.1 timers are used in this system. They output a signal after an input signal is received at a predetermined time.In addition, it is characterized by CAN ALSO OPERATE WITH 5V SUPPLY.Digital time clocks with 16 bits are designed for this application.
