DS1689S+ Overview

In the 28-SOIC (0.295, 7.50mm Width) package, real time clocks is embedded as a dependency.Tube is the package format.In this electrical RTC, the supply voltage is 2.7V~3.3V 4.5V~5.5V.Clock/Calendar is the type of electrical real time clock that is being used.As you can see from the diagram, this electronic component is mounted in the way of Surface Mount.There should be 0°C~70°C operating temperature.When operating, electronic time clocks are possible to ensure that NVSRAM are maintained.When a transmission line is terminated with 28 terminations, it means that the RTC module that terminates the line matches its characteristic impedance.It should be noted that this RTC real time clock is being supplied with 3V voltage at the moment.A total of 28 pins are equipped with the RTCs.The family in which RTCs belongs are DS1689.A voltage of 2.5V~3.7V is supplied to this electrical digital time clock.RTC times embed a memory of 114B for storing programs and data.The frequency of real time clocks' output should not exceed 0.032MHz.In order for it to be powered, it requires a power supply of 3/5V.When an input signal is received, 1 timers are used to output a signal at a preset time.The CAN ALSO OPERATE WITH 5V SUPPLY characteristics are also present.A digital time clock with 16 bits is designed for this application.
