DS1556W-120+ Product Details

DS1556W-120+ Overview


There is an embedded version in the package 32-DIP Module (0.600, 15.24mm).Packaged as Tube.This electrical RTC is powered by 2.97V~3.63V voltage.This electrical real time clock is of type Clock/Calendar.Through Hole is the way to mount this real time clock (RTC).A temperature of 0°C~70°C should be used for operation.During operation, Alarm, Leap Year, NVSRAM, Watchdog Timer, Y2K can be guaranteed.The 32 termination is the practice of terminating a transmission line with a RTC module matched to its characteristic impedance.It is possible to see 3.3V voltage being supplied to this RTC real time clock.32 pins are attached to it.RTCs are a member of the family DS1556.In these RTC times, there is a memory of 128KB where data and programs can be stored.This RTC module has a mounting type of Through Hole.32 pins are present on it.RTC time is important to maintain the supply voltage at 3.3V in order to maintain high efficiency.
