DS1284+ Overview
Real time clocks is embedded in the 28-DIP (0.600, 15.24mm) package.Time clock is packaged in the way of Tube.The supply voltage of this electrical RTC is 4.5V~5.5V.The type of this electrical real time clock is Clock/Calendar.This real time clock (RTC) is mounted in the way of Through Hole.The operating temperature should be 0°C~70°C.Alarm, Leap Year, Square Wave Output, SRAM, Watchdog Timer can be ensured when operating.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.The supply voltage of this RTC real time clock is 5V.It is equipped with 28 pins.The supply voltage of this electrical digital time clock is 2.4V~3.5V.The RTC times embed a memory of 50B available for storing programs and data.Real time clocks' output frequency should not exceed 0.032MHz.There are 1 timers, which are control real time clocks that output a signal at a preset time after an input signal is received.It is also characterized by ACCURACY 2 MIN/MONTH @ 25 DEGREE C; 1024 HZ FIXED O/P.
