MCP7940NT-I/MNY Product Details

MCP7940NT-I/MNY Overview


There is a package 8-WFDFN Exposed Pad that contains real time clocks.Tape & Reel (TR) is the way in which time clock is packaged.As far as the supply voltage for this electrical RTC is concerned, it is 1.8V~5.5V.This electrical real time clock belongs to the Clock/Calendar category.The way this real time clock (RTC) is mounted on the system board is Surface Mount.As far as the operating temperature are concerned, electronic time clocks should be -40°C~85°C.As long as Alarm, Leap Year, Square Wave Output, SRAM is ensured when operating, the system will work properly.With 8 terminations, transmission lines have the characteristic impedance of the RTC module terminating them.This RTC real time clock is powered by 2.5V volts.The board is equipped with a total of 8 pins.In the family MCP7940N, RTCs are a member.This electrical digital time clock is powered by a voltage that is 1.3V~5.5V at the time of installation.For storing the programs and data, the RTC times have an embedded memory of 64B for storing data and programs.A frequency above 0.032MHz should not be used for real time clocks' output.The mounting type of the RTC module is Surface Mount.There are 2/5V power supplies attached to it.It is equipped with 8 pins.In order to achieve high efficiency, the supply voltage should be kept at 2.5, 3.3, 5 V.Ideally, the operating temperature should be higher than -40 °C.Ideally, the operating temperature should be lower than 85 °C.The minimal supply voltage is 1.8 V.A maximum supply voltage of 5.5 V is used.It is a type of real time clock belonging to the Automotive, AEC-Q100 series.This electrical real time analog clock has the type TIMER, REAL TIME CLOCK of uPs/uCs/Peripheral ICs.
