ISL1221IUZ-T Product Details

ISL1221IUZ-T Overview


In the 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) package, real time clocks is embedded as a dependency.Cut Tape (CT) is the package format.In this electrical RTC, the supply voltage is 2.7V~5.5V.Time Event Recorder 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.When operating, electronic time clocks are possible to ensure that Alarm, Leap Year, SRAM are maintained.When a transmission line is terminated with 10 terminations, it means that the RTC module that terminates the line matches its characteristic impedance.It should be noted that this RTC real time clock is being supplied with 3V voltage at the moment.A total of 10 pins are equipped with the RTCs.The family in which RTCs belongs are ISL1221.A voltage of 1.8V~5.5V is supplied to this electrical digital time clock.RTC times embed a memory of 2B for storing programs and data.
