DS12CR887-33+ Overview
real time clocks is located in package 24-DIP Module (0.600, 15.24mm).As of Tube, time clock is packaged in this way.There is 2.97V~3.63V voltage supply for this electrical RTC.It can be said that this electrical real time clock belongs to the Clock/Calendar type.The real time clock (RTC) that is mounted in the way of Through Hole is connected to this circuit board.In order to operate properly, the temperature should be -40°C~85°C.During the course of operation, Alarm, Leap Year, NVSRAM, Square Wave Output, Trickle-Charger can be ensured.There is the possibility of terminating transmission lines with 24 terminations, which means that the equipment used to terminate the line will match its characteristic impedance.In this case, the voltage supplied to the electronic component is 3.3V.A total of 24 pins are included in this product.DS12CR887 are the family name of RTCs .As far as the supply voltage for this electrical digital time clock is concerned, it is 2V~3.05V.For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 114B.There should be no frequency greater than 0.032MHz in real time clocks' output.Mounting type Through Hole matches the RTC module.A total of 24 pins are attached to this real time clock.1 timer real time clocks send out a signal at a preset time based on input signals.Maintaining the supply voltage at 3.3V is the key to high efficiency.
