PT7C4311WEX Overview
A package named 8-SOIC (0.154, 3.90mm Width) contains real time clocks.Tape & Reel (TR) is the packaging method.There is 1.2V~5.5V supply voltage for this electrical RTC.Electrical real time clocks of this type are Clock/Calendar.real time clock (RTC)s like this are mounted in the way of Surface Mount.-40°C~85°C is the operating temperature.When operating, you can ensure Leap Year, Square Wave Output, Y2K.A transmission line can have a 8 termination by terminating it with a RTC module whose characteristic impedance matches the line's.In the case of this RTC real time clock, there is 2V voltage supplied to it.PT7C4311 is the family name of this object.This electrical digital time clock is powered by 2V~5.5V voltage.Programs and data can be stored in the 56B memory embedded in the RTC times.There should not be a frequency higher than 0.032MHz in the output.Mounting type for the RTC module is Surface Mount.8 pins are attached to it.1 timers are used in this system. They output a signal after an input signal is received at a predetermined time.
