DS1558W+TRL Overview
In the package 48-LQFP, you will find real time clocks, and you will be able to install real time clocks.Packaged as Tape & Reel (TR).There is 2.97V~3.63V supply voltage for this electrical RTC.Electrical real time clocks of type Clock/Calendar correspond to this real time clock.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 -40°C~85°C.If Alarm, Leap Year, Watchdog Timer, Y2K is ensured when operating, then the operation will be successful.The 48 termination is the practice of terminating a transmission line with a RTC module matched to its characteristic impedance.In this RTC real time clock, there is a voltage of 3.3V supplied to it.There are 48 pins on it.The family RTCs belongs to are DS1558.There is a voltage of 2.5V~3.7V when powering this electrical digital time clock.Timer or RTC includes this part.There should be no more than a 0.032MHz frequency at real time clocks' output.Mounting type is Surface Mount.With 48 pins, it is equipped.Maintaining the supply voltage at 3.3V is the key to high efficiency.
