X1227S8IZ-2.7AT1 Overview
In the 8-SOIC (0.154, 3.90mm Width) package, real time clocks is embedded as a dependency.Tape & Reel (TR) is the package format.In this electrical RTC, the supply voltage is 2.7 V ~ 5.5 V.Clock/Calendar is the type of electrical real time clock that is being used.As you can see from the diagram, this electronic component is mounted in the way of Surface Mount.There should be -40°C ~ 85°C operating temperature.It should be noted that this RTC real time clock is being supplied with 5V voltage at the moment.A total of 8 pins are equipped with the RTCs.The family in which RTCs belongs are X1227.A voltage of 1.8 V ~ 5.5 V is supplied to this electrical digital time clock.RTC times embed a memory of -- for storing programs and data.The frequency of real time clocks' output should not exceed 0.032MHz.When an input signal is received, 1 timers are used to output a signal at a preset time.In the series --, it belongs to the real-time clock category.It reaches a maximum supply voltage of 5.5V (Vsup).In this electrical real time analog clock, uPs/uCs/peripheral ICs are of the type TIMER, REAL TIME CLOCK.In order to maintain normal operation, the supply voltage (Vsup) must be kept above 2.7V.Under 85°C, the operating temperature should be maintained.
