DS1557P-70 Overview
In package 34-PowerCap? Module, real time clocks is located.Packaged as Tube.The supply voltage of this electrical RTC is 4.5V~5.5V.This electrical real time clock is of type Clock/Calendar.The position of this real time clock (RTC) on the system board is indicated by Surface Mount.The temperature should always be kept at 0°C~70°C to ensure safe operation.If Alarm, Leap Year, NVSRAM, Watchdog Timer, Y2K is ensured when operating, then the operation will be successful.Transmitter lines with 34 terminations exhibit the characteristic impedance of the terminating RTC module.This RTC real time clock is supplied with 5V voltage.The RTCs are equipped with the necessary features due to its 34 pins.DS1557 are a family of objects that belongs to RTCs .There is 3V supply voltage for this electrical digital time clock.There are such RTCs in Timer or RTC subcategory.In these RTC times, there is a memory of 512KB where data and programs can be stored.There should be no frequency greater than 0.032MHz in real time clocks' output.A mounting type of Surface Mount has been specified for this RTC module.There are 5V power supplies attached to it.The real time clock is equipped with 34 pins.RTC time is important to maintain the supply voltage at 5V in order to maintain high efficiency.
