DS1673E-3/T&R Overview
In the 20-TSSOP (0.173, 4.40mm 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~3.3V.Portable System Controller 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 Alarm, Leap Year, Watchdog Timer are maintained.The family in which RTCs belongs are DS1673.A voltage of 2.5V~3.7V is supplied to this electrical digital time clock.Mounting type Surface Mount is chosen for the RTC module.There are 20 pins on it.Optimal efficiency can be achieved by maintaining the supply voltage at 3V.A temperature higher than 0°C is ideal for operating.RTC time is recommended to keep the operating temperature below 70°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.
