DS14285Q Overview
This real time analog clock can be found in package 28-LCC (J-Lead).Tube is the way time clock is packaged, which is the way time clock is intended to be.There is a voltage of 4.5V~5.5V when powering this electrical RTC.This electrical real time clock is of type Clock/Calendar.This part is mounted on the systemboard in Surface Mount mode.Maintaining a constant temperature of 0°C~70°C is essential for safe operation.As long as Alarm, Daylight Savings, Leap Year, NVSRAM, Square Wave Output is ensured when operating, the system will work properly.It is possible to terminate a transmission line with a RTC module that matches the characteristic impedance of the line, which is known as 28 termination.This RTC real time clock's supply voltage is 5V.28 pins are present on it.In the family DS14285, RTCs are a member.A crucial thing to remember is that this electrical digital time clock has a supply voltage of 2.5V~3.6V.The RTCs belongs to the Timer or RTC subcategory.RTC times embed a memory of 114B for storing programs and data.The output frequency should not exceed 0.032MHz.RTC module mounting type Surface Mount is specified.For powering the real time clock, a power supply with a voltage of 5V is used.28 pins are attached to it.When an input signal is received, 1 timers are used to output a signal at a preset time.
