MCP7940NT-I/SN Product Details

MCP7940NT-I/SN Overview


In package 8-SOIC (0.154, 3.90mm Width), real time clocks is located.As a result, time clock is packaged in the same way as Tape & Reel (TR).A voltage of 1.8V~5.5V is required for the supply of this electrical RTC.Electrical real time clocks of type Clock/Calendar correspond to this real time clock.Surface Mount indicates how this real time clock (RTC) is mounted.Maintaining a constant temperature of -40°C~85°C is essential for safe operation.When operating as part of a process, electronic time clocks are possible to ensure that Alarm, Leap Year, Square Wave Output, SRAM are maintained at all times.8 terminations result in transmission lines having the characteristic impedance of a RTC module terminating them.This RTC real time clock's supply voltage is 2.5V.It is equipped with the necessary features since it has 8 pins.Thare RTCs em are part of the family MCP7940N.Note that the supply voltage is 1.3V~5.5V for this electrical digital time clock.There is a memory size of 64B available for storing data and programs on the real time analog clocks.There should be no more than a 0.032MHz frequency at real time clocks' output.Amounting type Surface Mount is the one associated with the RTC module.There is a power supply of 2/5V used to power the real time clock.8 pins are attached to it.Optimal efficiency requires a supply voltage of 2.5, 3.3, 5 V.A temperature above -40 °C is recommended for operation.Lower than 85 °C is the recommended operating temperature.Real time clocks operate with a voltage of 1.8 V.There is 5.5 V maximum supply voltage for real time clocks.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.
