DS12R887-33 Product Details

DS12R887-33 Overview


There is an embedded version in the package 48-BBGA.Packaged as Tray.This electrical RTC is powered by 2.97V~3.63V voltage.This electrical real time clock is of type Clock/Calendar.Surface Mount is the way to mount this real time clock (RTC).A temperature of -40°C~85°C should be used for operation.During operation, Alarm, Leap Year, NVSRAM, Square Wave Output, Trickle-Charger can be guaranteed.The 48 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.48 pins are attached to it.RTCs are a member of the family DS12R887.Its supply voltage is 2V~3.05V.In these RTC times, there is a memory of 114B where data and programs can be stored.There should be no more than 0.032MHz frequency in real time clocks' output.48 pins are present on it.In this system, there are 1 timers, which are real time clocks that output a signal at a preset time after an input signal is received.RTC time is important to maintain the supply voltage at 3.3V in order to maintain high efficiency.
