MCP7940M-I/ST Overview


You can find real time clocks in package 8-TSSOP (0.173, 4.40mm Width) among the other packages that are available.Tube is the packaging method.A voltage of 1.8V~5.5V is required for the supply of this electrical RTC.There is a type of electrical real time clock Clock/Calendar associated with this real time clock.Here, Surface Mount represents how this part is mounted.There should be -40°C~85°C operating temperature.If Alarm, Leap Year, Square Wave Output, SRAM is ensured during operation, then there is no problem.Transmitter lines with 8 terminations exhibit the characteristic impedance of the terminating RTC module.In this RTC real time clock, there is a voltage of 2.5V supplied to it.As a member of the MCP7940M family, RTCs belongs to them.Timer or RTC is the subcategory in which the RTCs belongs.In order for it to be powered, it requires a power supply of 2/5V.It is equipped with 8 pins.1 timer real time clocks send out a signal at a preset time based on input signals.
