DS1501W Overview


The package 28-DIP (0.600, 15.24mm) contains real time clocks.Packaged as Tube.Its supply voltage is 3V~3.6V.In this case, we are dealing with an electrical real time clock that has a type of Clock/Calendar.As you can see from the diagram, this electronic component is mounted in the way of Through Hole.Electronic time clocks are recommended to operate at a temperature of 0°C~70°C.In order to ensure Alarm, Leap Year, NVSRAM, Square Wave Output, Watchdog Timer, Y2K when operating, a certain value has to be set.There are 28 terminations, which are the practice of ending a transmission line welectronic time clocksh a RTC module that matches the characteristic impedance of the line.3.3V voltage is present on this electronic component.With 28 pins, it is equipped with the necessary functions.The family RTCs belongs to are DS1501.A crucial thing to remember is that this electrical digital time clock has a supply voltage of 2.5V~3.7V.This component can be found in Timers or RTCs.In these RTC times, there is a memory of 256B where data and programs can be stored.Neither real time clocks' output frequency nor real time clocks' response frequency should exceed 0.032MHz.In this case, the RTC module is mounted in the way of Through Hole.The real time clock is equipped with 28 pins.1 timer real time clocks send out a signal at a preset time based on input signals.Maintaining the supply voltage at 3.3V is the key to high efficiency.
