DS1644-120+ Product Details

DS1644-120+ Overview


The package 28-DIP Module (0.600, 15.24mm) contains real time clocks.The package is in the form of Tube.This electrical RTC has a supply voltage of 4.5V~5.5V.This electrical real time clock has the type Clock/Calendar.Through Hole is the way this real time clock (RTC) is mounted.Electronic time clocks are recommended that the operating temperature be 0°C~70°C.When operating, Leap Year, NVSRAM can be ensured.It is possible to terminate a transmission line with a RTC module that matches the characteristic impedance of the line, which is known as 28 termination.Obviously, a voltage of 5V is being supplied to this electronic component.There are 28 pins on it.The family RTCs belongs to are DS1644.For storing data and programs, the RTC times embed a memory of 32KB.There are 5V power supplies attached to it.It is equipped with 28 pins.
