MCP7940NT-E/SN Product Details

MCP7940NT-E/SN Overview


Real time clocks is embedded in the 8-SOIC (0.154, 3.90mm Width) package.Time clock is packaged in the way of Tape & Reel (TR).The supply voltage of this electrical RTC is 1.8V~5.5V.The type of this electrical real time clock is Clock/Calendar.This real time clock (RTC) is mounted in the way of Surface Mount.The operating temperature should be -40°C~125°C.Alarm, Leap Year, Square Wave Output, SRAM can be ensured when operating.There are 8 terminations, which are the practice of ending a transmission line welectronic time clocksh a RTC module that matches the characteristic impedance of the line.The supply voltage of this RTC real time clock is 2.5V.It is equipped with 8 pins.RTCs belongs to MCP7940N family.The supply voltage of this electrical digital time clock is 1.3V~5.5V.The RTC times embed a memory of 64B available for storing programs and data.It operates from 2/5V power supplies.There are 8 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock. There are 1 timers, which are control real time clocks that output a signal at a preset time after an input signal is received.The supply voltage should be maintained at 2.5, 3.3, 5 V for high efficiency.It is a type of real time clock belonging to the Automotive, AEC-Q100 series.The uPs/uCs/Peripheral ICs type of this electrical real time analog clock is TIMER, REAL TIME CLOCK.
