DS1643AL-120 Overview
In package 34-LPM, real time clocks is located.As a result, time clock is packaged in the same way as Tube.A voltage of 4.5V~5.5V is required for the supply of this electrical RTC.Electrical real time clocks of type Clock/Calendar correspond to this real time clock.Surface Mount indicates how this real time clock (RTC) is mounted.Maintaining a constant temperature of 0°C~70°C is essential for safe operation.When operating as part of a process, electronic time clocks are possible to ensure that Leap Year, NVSRAM are maintained at all times.Thare RTCs em are part of the family DS1643.There is a memory size of 8KB available for storing data and programs on the real time analog clocks.Amounting type Surface Mount is the one associated with the RTC module.34 pins are attached to it.
