DS1557P-70 Overview
In package 34-PowerCap? Module, real time clocks is located.Tube is the way time clock is packaged, which is the way time clock is intended to be.This electrical RTC has a supply voltage of 4.5V~5.5V.The electrical real time clock belongs to the type Clock/Calendar.On the system board, this real time clock (RTC) is mounted in Surface Mount.As far as the operating temperature are concerned, electronic time clocks should be 0°C~70°C.If Alarm, Leap Year, NVSRAM, Watchdog Timer, Y2K is ensured when operating, then the operation will be successful.The 34 termination is the practice of terminating a transmission line with a RTC module matched to its characteristic impedance.Obviously, a voltage of 5V is being supplied to this electronic component.34 pins are present on it.The voltage supply of this electrical digital time clock is 3V.In the real time analog clocks, the available memory size is 512KB.A frequency above 0.032MHz should not be used for real time clocks' output.
