MCP7940N-E/MS Product Details

MCP7940N-E/MS Overview


In the package 8-TSSOP, 8-MSOP (0.118, 3.00mm Width), you will find real time clocks, and you will be able to install real time clocks.As you can see, time clock is packaged as if time clock were in the form of Tube.Providing this electrical RTC with a voltage of 1.8V~5.5V is required.There is a type Clock/Calendar for this electrical real time clock.Surface Mount is the way this real time clock (RTC) is mounted on the system board.Keeping the temperature at -40°C~125°C is essential to maintaining a safe working environment.There is a way to make sure that Alarm, Leap Year, Square Wave Output, SRAM is maintained when operating if desired.Transmitter lines with 8 terminations exhibit the characteristic impedance of the terminating RTC module.There is 2.5V voltage supplied to this RTC real time clock.The reason for this is that, due to the fact that it has 8 pins, it has the necessary features.There are only one family in which RTCs belongs, and that are MCP7940N.The supply voltage of this electrical digital time clock is 1.3V~5.5V.A total of 64B of memory is available for storing data and programs on the real time analog clocks.For powering the real time clock, a power supply with a voltage of 2/5V is used.A total of 8 pins are attached to this real time clock.1 timer real time clocks send out a signal at a preset time based on input signals.Maintaining the supply voltage at 2.5, 3.3, 5 V is the key to high efficiency.It is a real-time clock in the series Automotive, AEC-Q100.A TIMER, REAL TIME CLOCK is the type of uPs, uCs, and peripheral ICs found in this electrical real time analog clock.
