DS1284QN+ Overview
There is a version of real time clocks in the package 28-LCC (J-Lead).There is a packaging method that is similar to Tube.The supply voltage of this electrical RTC is 4.5V~5.5V.Electrical real time clock type Clock/Calendar.In this case, Surface Mount is the way this part is mounted on the systemboard.Maintaining a constant temperature of -40°C~85°C is essential for safe operation.During the course of operation, Alarm, Leap Year, Square Wave Output, SRAM, Watchdog Timer can be ensured.Transmitter lines with 28 terminations exhibit the characteristic impedance of the terminating RTC module.5V is the supply voltage of this RTC real time clock.There are 28 pins on it.The family in which RTCs belongs are DS1284.Keeping in mind that the supply voltage of this electrical digital time clock is 2.4V~3.5V is important.A part like this is included in Timer or RTC.In the RTC times you will find a memory of 50B which is available for your programs and data storage.A frequency of 0.032MHz should not be exceeded by real time clocks' output frequency.In order for it to be powered, it requires a power supply of 5V.There are 1 timers, which are control real time clocks that output a signal at a preset time after an input signal is received.The ACCURACY 2 MIN/MONTH @ 25 DEGREE C; 1024 HZ FIXED O/P characteristics are also present.
