DS1511W+ Overview
In the package 28-DIP Module (0.600, 15.24mm), 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 3V~3.6V is required.There is a type Clock/Calendar for this electrical real time clock.Through Hole 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, Watchdog Timer, Y2K is maintained when operating if desired.Transmitter lines with 28 terminations exhibit the characteristic impedance of the terminating RTC module.There is 3.3V voltage supplied to this RTC real time clock.The reason for this is that, due to the fact that it has 28 pins, it has the necessary features.There are only one family in which RTCs belongs, and that are DS1511.The supply voltage of this electrical digital time clock is 2.5V~3.7V.A total of 256B of memory is available for storing data and programs on the real time analog clocks.It should not exceed 0.032MHz as the output frequency of the real time analog clock.For powering the real time clock, a power supply with a voltage of 3.3V is used.A total of 28 pins are attached to this real time clock.1 timer real time clocks send out a signal at a preset time based on input signals.With 11 outputs, the real time analog clock is configured.
