DS1556W-120 Overview
In the 32-DIP Module (0.600, 15.24mm) package, real time clocks is embedded as a dependency.Time clock is packaged in the way of Tube.Unless otherwise stated, this electrical RTC's supply voltage is 2.97V~3.63V.Electrical real time clocks of this type are Clock/Calendar.The way this real time clock (RTC) is mounted on the system board is Through Hole.In order to operate properly, the temperature should be 0°C~70°C.If Alarm, Leap Year, NVSRAM, Watchdog Timer, Y2K is ensured during operation, then there is no problem.When transmission lines are terminated with a zero, their characteristic impedance is that of the terminating RTC module.3.3V is the supply voltage of this RTC real time clock.A total of 32 pins are attached to this RTCs.In these RTC times, there is a memory of 128KB where data and programs can be stored.0.032MHz should be the maximum output frequency.
