DS1685E-3+ Overview
24-TSSOP (0.173, 4.40mm Width) contains real time clocks.A Tube package is used to package time clock.Its supply voltage is 2.7V~3.7V.It is a Clock/Calendar type electrical real time clock.A part of this electronic RTC module is mounted in the way of Surface Mount.Electronic time clocks should be 0°C~70°C degrees Celsius during operation.Electronic time clocks are possible to guarantee Alarm, NVSRAM, Square Wave Output, Y2K when operating.Transmission lines can be terminated with 24 terminations, which means that the RTC module that terminates the line matches its characteristic impedance.In this RTC real time clock, there is a voltage of 3V supplied to it.24 pins are present on it.DS1685 are RTC s family.2.5V~3.7V is the supply voltage of this electrical digital time clock.A memory of 242B is embedded into the RTC times for storing programs and data.A frequency of 0.032MHz should not be exceeded by real time clocks' output.There is a mounting type of Surface Mount for this RTC module.The power supply is 3V.With 24 pins, it is equipped.1 timers are in the real time clock that outputs a signal in response to an input signal.Maintaining a voltage of 3V will result in high efficiency.
