DS1284QN+ Product Details

DS1284QN+ Overview


There is a package 28-LCC (J-Lead) that contains real time clocks.Tube is the way in which time clock is packaged.As far as the supply voltage for this electrical RTC is concerned, it is 4.5V~5.5V.This electrical real time clock belongs to the Clock/Calendar category.The way this real time clock (RTC) is mounted on the system board is Surface Mount.As far as the operating temperature are concerned, electronic time clocks should be -40°C~85°C.As long as Alarm, Leap Year, Square Wave Output, SRAM, Watchdog Timer is ensured when operating, the system will work properly.With 28 terminations, transmission lines have the characteristic impedance of the RTC module terminating them.This RTC real time clock is powered by 5V volts.The board is equipped with a total of 28 pins.In the family DS1284, RTCs are a member.This electrical digital time clock is powered by a voltage that is 2.4V~3.5V at the time of installation.For storing the programs and data, the RTC times have an embedded memory of 50B for storing data and programs.A frequency above 0.032MHz should not be used for real time clocks' output.There are 5V power supplies attached to it.Upon receiving an input signal, 1 timers output a signal at a preset time.ACCURACY 2 MIN/MONTH @ 25 DEGREE C; 1024 HZ FIXED O/P are also characteristics of it.
