MCP79412-I/MS Overview
In the 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) package, real time clocks is embedded as a dependency.Tube is the package format.In this electrical RTC, the supply voltage is 1.8V~5.5V.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.When operating, electronic time clocks are possible to ensure that Alarm, Leap Year, Square Wave Output, SRAM, Unique ID are maintained.When a transmission line is terminated with 8 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 5V voltage at the moment.A total of 8 pins are equipped with the RTCs.The family in which RTCs belongs are MCP79412.A voltage of 1.3V~5.5V is supplied to this electrical digital time clock.RTC times embed a memory of 64B 1Kb for storing programs and data.The frequency of real time clocks' output should not exceed 0.4MHz.Mounting type Surface Mount is chosen for the RTC module.In order for it to be powered, it requires a power supply of 2/5V.There are 8 pins on it.Optimal efficiency can be achieved by maintaining the supply voltage at 2.5, 3.3, 5 V.A temperature higher than -40 °C is ideal for operating.RTC time is recommended to keep the operating temperature below 85 °C.Minimum supply voltage is 1.8 V, so real time clocks can operate on any voltage.Real time clocks are powered by a voltage of 5.5 V, which is its maximum supply voltage.In the series --, it belongs to the real-time clock category.In this electrical real time analog clock, uPs/uCs/peripheral ICs are of the type TIMER, REAL TIME CLOCK.The ALSO OPERATES AT 100KHZ WITH 1.8 V NOMINAL characteristics are also present.
