DS1388Z-3+ Overview
In the 8-SOIC (0.154, 3.90mm 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.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 -40°C~85°C operating temperature.When operating, electronic time clocks are possible to ensure that EEPROM, Leap Year, Supervisor, Trickle-Charger, Watchdog Timer are maintained.When a transmission line is terminated with 8 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 8 pins are equipped with the RTCs.The family in which RTCs belongs are DS1388.A voltage of 1.3V~5.5V is supplied to this electrical digital time clock.RTC times embed a memory of 512B for storing programs and data.The frequency of real time clocks' output should not exceed 0.032MHz.Mounting type Surface Mount is chosen for the RTC module.In order for it to be powered, it requires a power supply of 3V.There are 8 pins on it.Optimal efficiency can be achieved by maintaining the supply voltage at 3V.
