MCP7940N-I/ST Product Details

MCP7940N-I/ST Overview

8-TSSOP (0.173, 4.40mm Width) contains real time clocks.The package is in the form of Tube.This electrical RTC has a supply voltage of 1.8V~5.5V.An electrical real time clock of this type is called a Clock/Calendar.This electronic component has been mounted in the way of Surface Mount.Ideally, the operating temperature should be -40°C~85°C.During operation, Alarm, Leap Year, Square Wave Output, SRAM can be guaranteed.It is possible to terminate transmission lines with 8 terminations, which means that the RTC module terminating the line matches its characteristic impedance.This RTC real time clock is powered by 2.5V volts.There are 8 pins on it.MCP7940N are RTC s family.As far as the supply voltage for this electrical digital time clock is concerned, it is 1.3V~5.5V.It falls under the subcategory of Timer or RTC.A frequency above 0.032MHz should not be used for real time clocks' output.There is a mounting type Surface Mount specified for the RTC module.A power supply of 2/5V is used to power it.8 pins are present on it.In the series Automotive, AEC-Q100, it belongs to the real-time clock category.
