X1227S8-2.7 Overview
8-SOIC (0.154, 3.90mm Width) contains real time clocks.A Tube package is used to package time clock.Its supply voltage is 2.7V~5.5V.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, Leap Year, Supervisor, Watchdog Timer when operating.Transmission lines can be terminated with 8 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 5V supplied to it.8 pins are present on it.1.8V~5.5V is the supply voltage of this electrical digital time clock.A frequency of 0.032MHz should not be exceeded by real time clocks' output.1 timers are in the real time clock that outputs a signal in response to an input signal.
