DS1340U-3+T&R Product Details

DS1340U-3+T&R Overview


In the 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) package, real time clocks is embedded as a dependency.Tape & Reel (TR) is the package format.In this electrical RTC, the supply voltage is 2.7V~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, Trickle-Charger are maintained.The family in which RTCs belongs are DS1340.A voltage of 1.3V~3.7V is supplied to this electrical digital time clock.Mounting type Surface Mount is chosen for the RTC module.There are 8 pins on it.Optimal efficiency can be achieved by maintaining the supply voltage at 3V.A temperature higher than -40°C is ideal for operating.RTC time is recommended to keep the operating temperature below 85°C.Minimum supply voltage is 2.7V, so real time clocks can operate on any voltage.Real time clocks are powered by a voltage of 3.3V, which is its maximum supply voltage.
