X1228S14I-2.7A Overview
SOIC contains real time clocks.A Bulk package is used to package time clock.Transmission lines can be terminated with 14 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.14 pins are present on it.A memory of 512B 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 3/5V.1 timers are in the real time clock that outputs a signal in response to an input signal.Over -40°C is the recommended operating temperature.RTC time is recommended that the operating temperature is lower than 85°C.It reaches 5.5V when the maximal supply voltage (Vsup) is reached.This electrical real time analog clock has TIMER, REAL TIME CLOCK for uPs/uCs/Peripheral ICs.For normal operation, Vsup must be above 2.7V.
