M41T66Q6F Overview
Real time clocks is embedded in the 16-VFQFN Exposed Pad package.Time clock is packaged in the way of Tape & Reel (TR).The supply voltage of this electrical RTC is 1.5V~4.4V.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~85°C.Alarm, Leap Year, Square Wave Output, Watchdog Timer can be ensured when operating.There are 16 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 1.6V.It is equipped with 16 pins.RTCs belongs to M41T66 family.It is mounted in the way of Surface Mount.It operates from 2/4V power supplies.There are 16 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.It is a type of real time clock belonging to the Timekeeper® series.
