DS17885E-3+ Overview


This real time analog clock can be found in package 28-TSSOP (0.465, 11.80mm Width).In this case, time clock is packaged in the way of Tray.This electrical RTC is powered by 2.7V~3.7V voltage.This electrical real time clock is type Clock/Calendar.It should be noted that the real time clock (RTC) is mounted in the way of Surface Mount.There should be 0°C~70°C operating temperature.When operating, electronic time clocks are possible to make sure that Alarm, Daylight Savings, Leap Year, NVSRAM, Square Wave Output remains constant in the process.Transmission lines can be terminated with 28 terminations, which means that the RTC module that terminates the line matches its characteristic impedance.RTC real time clocks such as this one are powered by 3V voltage.28 pins are attached to it.Thare RTCs em are part of the family DS17885.Keeping in mind that the supply voltage of this electrical digital time clock is 2.5V~3.7V is important.Timer or RTC is the subcategory in which the RTCs belongs.The RTC times embed a memory of 8KB available for storing programs and data.The output frequency should not exceed 0.032MHz.It appears that the RTC module's mounting type is Surface Mount.A total of 3V power supplies are required to operate it.A total of 28 pins are equipped with the real time clock.1 timer real time clocks send out a signal at a preset time based on input signals.Optimal efficiency can be achieved by maintaining the supply voltage at 3V.
