M41T256YMT7F Overview


In the 44-BSOP (0.337, 8.56mm Width) package, real time clocks is embedded as a dependency.Time clock is packaged in the manner of Tape & Reel (TR).This electrical RTC has a supply voltage of 4.5V~5.5V.Clock/Calendar is the type of this electrical real time clock.There is an electronic component mounted in the way of Surface Mount.A safe operation requires a temperature of -25°C~70°C at all times.When operating as part of a process, electronic time clocks are possible to ensure that Leap Year, NVSRAM are maintained at all times.Transmission lines with 44 terminations have the characteristic impedance of their termination RTC modules.In the case of this RTC real time clock, there is 5V voltage supplied to it.As it has 44 pins, it is equipped with the necessary features.There are only one family in which RTCs belongs, and that are M41T256.This electrical digital time clock has a 2.5V~3.5V supply voltage.In Timer or RTC, this part is included.The RTC times embed a memory of 32KB available for storing programs and data.In order for it to work properly, real time clocks' output frequency should not exceed 0.032MHz.There is a mounting type Surface Mount specified for the RTC module.For powering the real time clock, a power supply with a voltage of 5V is used.There are 44 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock. Real-time clocks belonging to the Timekeeper? series are this type.
