DS1556W-120IND+ Product Details

DS1556W-120IND+ Overview


real time clocks is located in package 32-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, Watchdog Timer, Y2K can be ensured.There is the possibility of terminating transmission lines with 32 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 32 pins are included in this product.DS1556 are the family name of RTCs .For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 128KB.Mounting type Through Hole matches the RTC module.A total of 32 pins are attached to this real time clock.Maintaining the supply voltage at 3.3V is the key to high efficiency.
