DS1685E-3 Overview


Real time clocks is embedded in the 24-TSSOP (0.173, 4.40mm Width) package.Basically, time clock is packaged in a way that is equivalent to Tube.It requires a voltage of 2.7V~3.7V to be supplied.This electrical real time clock is type Clock/Calendar.A part of this electronic RTC module 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.When operating as part of a process, electronic time clocks are possible to ensure that Alarm, NVSRAM, Square Wave Output, Y2K are maintained at all times.A transmission line can have a 24 termination by terminating it with a RTC module whose characteristic impedance matches the line's.3V is the supply voltage of this RTC real time clock.As it has 24 pins, it is equipped with the necessary features.There is a voltage of 2.5V~3.7V when powering this electrical digital time clock.In the RTC times you will find a memory of 242B which is available for your programs and data storage.It should not exceed 0.032MHz as the output frequency of the real time analog clock.There are 1 timers, which are control real time clocks that output a signal at a preset time after an input signal is received.
