DS1284Q Overview
In package 28-LCC (J-Lead), real time clocks can be found.The package is packaged in the way of Tube.This electrical RTC has a supply voltage of 4.5V~5.5V.Clock/Calendar is the type of this electrical real time clock.This real time clock (RTC) is mounted in the way of Surface Mount.In order to be safe, electronic time clocks are imperative that the temperature are kept at 0°C~70°C at all times.In order to ensure Alarm, Leap Year, Square Wave Output, SRAM, Watchdog Timer when operating, a certain value has to be set.When a transmission line is terminated with 28 terminations, it means that the RTC module that terminates the line matches its characteristic impedance.A voltage of 5V is applied to this electronic component.28 pins are attached to it.In terms of RTCs family, RTCs belongs to DS1284.This electrical digital time clock's supply voltage is 2.4V~3.5V.There is a component of this type in Timer or RTC.A memory of 50B is embedded into the RTC times for storing programs and data.It should not exceed 0.032MHz as the output frequency of the real time analog clock.This RTC module has a mounting type of Surface Mount.The power supply is 5V.It is equipped with 28 pins.An input signal is received by 1 timers, which output a signal after a preset time.Furthermore, ACCURACY 2 MIN/MONTH @ 25 DEGREE C; 1024 HZ FIXED O/P are its characteristics.
