DS1284 Overview
In the 28-DIP (0.600, 15.24mm) package, real time clocks is embedded.Tube is the packaging method.It requires a voltage of 4.5V~5.5V to be supplied.It can be said that this electrical real time clock belongs to the Clock/Calendar type.Through Hole is the way to mount this real time clock (RTC).Ideally, the operating temperature should be set to 0°C~70°C.When operating as part of a process, electronic time clocks are possible to ensure that Alarm, Leap Year, Square Wave Output, SRAM, Watchdog Timer are maintained at all times.Transmitter lines with 28 terminations exhibit the characteristic impedance of the terminating RTC module.In this RTC real time clock, there is a voltage of 5V supplied to it.It has a total of 28 pins on it.The family in which RTCs belongs are DS1284.This electrical digital time clock has a supply voltage of 2.4V~3.5V.The content of Timer or RTC includes this component.For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 50B.A frequency of 0.032MHz should not be exceeded by real time clocks' output.Mounting type for the RTC module is Through Hole.In order for it to be powered, it requires a power supply of 5V.A total of 28 pins are attached to this real time clock.Following an input signal, there are 1 timers that output a signal at a preset time.Maintaining the supply voltage at 5V is the key to high efficiency.Also, ACCURACY 2 MIN/MONTH @ 25 DEGREE C; 1024 HZ FIXED O/P characterize it.
