MCP7940M-I/MS Overview
8-TSSOP, 8-MSOP (0.118, 3.00mm Width) contains real time clocks.A Tube package is used to package time clock.Its supply voltage is 1.8V~5.5V.It is a Clock/Calendar type electrical real time clock.A part of this electronic RTC module is mounted in the way of Surface Mount.Electronic time clocks should be -40°C~85°C degrees Celsius during operation.Electronic time clocks are possible to guarantee Alarm, Leap Year, Square Wave Output, SRAM when operating.Transmission lines can be terminated with 8 terminations, which means that the RTC module that terminates the line matches its characteristic impedance.In this RTC real time clock, there is a voltage of 2.5V supplied to it.MCP7940M are RTC s family.-- is the supply voltage of this electrical digital time clock.A memory of 64B is embedded into the RTC times for storing programs and data.The power supply is 2/5V.With 8 pins, it is equipped.1 timers are in the real time clock that outputs a signal in response to an input signal.In the -- series, it is a type of real time clock.
