DS1308U-33+ Product Details

DS1308U-33+ Overview


In the 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) package, real time clocks is embedded as a dependency.Tube is the package format.In this electrical RTC, the supply voltage is 3V~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 -40°C~85°C operating temperature.When operating, electronic time clocks are possible to ensure that Leap Year, NVSRAM, Square Wave Output 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 3.3V voltage at the moment.A total of 8 pins are equipped with the RTCs.The family in which RTCs belongs are DS1308.A voltage of 1.3V~5.5V is supplied to this electrical digital time clock.RTC times embed a memory of 56B 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 3.3/5V.There are 8 pins on it.Optimal efficiency can be achieved by maintaining the supply voltage at 3.3V.
