DS1557WP-120 Overview
34-PowerCap? Module is where you'll find real time clocks.The package is in the form of Tube.Electrical RTCs such as this have a 2.97V~3.63V supply.This electrical real time clock has the type Clock/Calendar.Here, Surface Mount represents how this part is mounted.Electronic time clocks are recommended that the operating temperature be 0°C~70°C.When operating, electronic time clocks are possible to ensure that Alarm, Leap Year, NVSRAM, Watchdog Timer, Y2K are maintained.The 34 termination is the practice of terminating a transmission line with a RTC module matched to its characteristic impedance.This RTC real time clock is powered by 3.3V volts.It is equipped with 34 pins.There is a voltage of 3V when powering this electrical digital time clock.In the real time analog clocks, the available memory size is 512KB.There should not be a frequency higher than 0.032MHz in the output.
