DS1553W-150 Overview
28-DIP Module (0.600, 15.24mm) contains real time clocks.A Tube package is used to package time clock.Its supply voltage is 2.97V~3.63V.It is a Clock/Calendar type electrical real time clock.A part of this electronic RTC module is mounted in the way of Through Hole.Electronic time clocks should be 0°C~70°C degrees Celsius during operation.Electronic time clocks are possible to guarantee Alarm, Leap Year, NVSRAM, Watchdog Timer, Y2K when operating.Transmission lines can be terminated with 28 terminations, which means that the RTC module that terminates the line matches its characteristic impedance.In this RTC real time clock, there is a voltage of 3.3V supplied to it.28 pins are present on it.3V is the supply voltage of this electrical digital time clock.A memory of 8KB is embedded into the RTC times for storing programs and data.A frequency of 0.032MHz should not be exceeded by real time clocks' output.
