DS1284QN Overview
The package 28-LCC (J-Lead) contains real time clocks.A Tube package is used to package time clock.This electrical RTC is powered by a voltage that is 4.5V~5.5V at the time of installation.Electrical real time clocks of this type are Clock/Calendar.This part is mounted on the systemboard in the way indicated by Surface Mount.-40°C~85°C should be the operating temperature.Operating with Alarm, Leap Year, Square Wave Output, SRAM, Watchdog Timer are possible.There are 28 terminations, which are the practice of ending a transmission line welectronic time clocksh a RTC module that matches the characteristic impedance of the line.This electronic component receives a voltage of 5V.The RTCs are equipped with 28 pins.DS1284 are the family RTCs belongs to.A voltage of 2.4V~3.5V is required for the supply of this electrical digital time clock.Timer or RTC includes this component as part of its contents.A real time analog clock's memory size is 50B, which is available for storing programs and data.A frequency of 0.032MHz should not be exceeded by real time clocks' output frequency.It appears that the RTC module's mounting type is Surface Mount.The power supply is 5V.A total of 28 pins are equipped with the real time clock.In this system, there are 1 timers, which are real time clocks that output a signal at a preset time after an input signal is received.Also, ACCURACY 2 MIN/MONTH @ 25 DEGREE C; 1024 HZ FIXED O/P characterize it.
