DS12R887-5 Overview
In the 48-BBGA package, real time clocks is embedded.As you can see, time clock is packaged as if time clock were in the form of Tray.There is 4.5V~5.5V voltage supply for this electrical RTC.There is a type Clock/Calendar for this electrical real time clock.The way this real time clock (RTC) is mounted on the system board is Surface Mount.There should be a temperature of -40°C~85°C during the operation.If Alarm, Leap Year, NVSRAM, Square Wave Output, Trickle-Charger 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.5V voltage is present on this electronic component.A total of 24 pins are attached to this RTCs.The family RTCs belongs to are DS12R887.Note that the supply voltage is 2V~3.05V for this electrical digital time clock.In Timer or RTC, you can find this component.A memory of 114B can be used to store data and programs.0.032MHz should be the maximum output frequency.For powering the real time clock, a power supply with a voltage of 5V is used.There are 48 pins on it.1 timers are in the real time clock that outputs a signal in response to an input signal.Maintaining the supply voltage at 5V is the key to high efficiency.
