DS12885Q Overview
real time clocks is located in package 28-LCC (J-Lead).Tube is the package format.A voltage of 4.5V~5.5V is required for the supply of this electrical RTC.This electrical real time clock belongs to the Clock/Calendar category.As you can see from the diagram, this electronic component is mounted in the way of Surface Mount.In order to be safe, electronic time clocks are imperative that the temperature are kept at 0°C~70°C at all times.Operating with Alarm, Daylight Savings, Leap Year, NVSRAM, Square Wave Output are possible.There are 28 terminations for transmission lines, which means that the RTC module that terminates the line matches its characteristic impedance.In the case of this RTC real time clock, there is 5V voltage supplied to it.With its 28 pins, it has the necessary functions.The voltage supply of this electrical digital time clock is 2.5V~4V.For storing the programs and data, the RTC times have an embedded memory of 114B for storing data and programs.It should not exceed 0.032MHz as the output frequency of the real time analog clock.1 timers are control real time clocks that emits a signal after receiving an input signal at a predetermined time.DAYLIGHT SAVINGS OPTION; SELECTABLE MOTOROLA/INTEL TIMING are other characteristics of it.
