MCP7940N-E/SN Product Details

MCP7940N-E/SN Overview


A package named 8-SOIC (0.154, 3.90mm Width) contains real time clocks.Tube is the packaging method.There is 1.8V~5.5V supply voltage for this electrical RTC.Electrical real time clocks of this type are Clock/Calendar.real time clock (RTC)s like this are mounted in the way of Surface Mount.-40°C~125°C is the operating temperature.When operating, you can ensure Alarm, Leap Year, Square Wave Output, SRAM.A transmission line can have a 8 termination by terminating it with a RTC module whose characteristic impedance matches the line's.In the case of this RTC real time clock, there is 2.5V voltage supplied to it.The RTCs are equipped with 8 pins.MCP7940N is the family name of this object.This electrical digital time clock is powered by 1.3V~5.5V voltage.Programs and data can be stored in the 64B memory embedded in the RTC times.Mounting type for the RTC module is Surface Mount.There is a power supply of 2/5V used to power the real time clock.8 pins are attached to it.1 timers are used in this system. They output a signal after an input signal is received at a predetermined time.Optimal efficiency requires a supply voltage of 2.5, 3.3, 5 V.Real time clocks of the series Automotive, AEC-Q100 are of this type.An electrical real time analog clock like this has a type TIMER, REAL TIME CLOCK for uPs/uCs/Peripheral ICs.
