In the package 20-TSSOP (0.173, 4.40mm Width), you will find real time clocks, and you will be able to install real time clocks.As you can see, time clock is packaged as if time clock were in the form of Tube.Providing this electrical RTC with a voltage of 2V~5.5V is required.There is a type Clock/Calendar for this electrical real time clock.Surface Mount is the way this real time clock (RTC) is mounted on the system board.Keeping the temperature at 0°C~70°C is essential to maintaining a safe working environment.There is a way to make sure that Alarm, Leap Year, NVSRAM, Square Wave Output, Trickle-Charger is maintained when operating if desired.Transmitter lines with 20 terminations exhibit the characteristic impedance of the terminating RTC module.There is 5V voltage supplied to this RTC real time clock.The reason for this is that, due to the fact that it has 20 pins, it has the necessary features.There are only one family in which RTCs belongs, and that are DS1306.The supply voltage of this electrical digital time clock is 2V~5.5V.A total of 96B of memory is available for storing data and programs on the real time analog clocks.A mounting type of Surface Mount has been specified for this RTC module.A total of 20 pins are attached to this real time clock.There is a frequency of 32.8kHz that can be achieved.With 3 outputs, the real time analog clock is configured.
