M41T256YMH7E Overview
In the 44-BSOP (0.337, 8.56mm Width) requires SNAPHAT package, real time clocks is embedded.Tube is the way time clock is packaged.A voltage of 4.5V~5.5V is supplied to this electrical RTC.It can be said that this electrical real time clock belongs to the Clock/Calendar type.Surface Mount is the way to mount this real time clock (RTC).Maintaining a constant temperature of -25°C~70°C is essential for safe operation.Electronic time clocks are possible to guarantee Leap Year, NVSRAM when operating.Transmission lines can be terminated with 44 terminations, which means that the RTC module that terminates the line matches its characteristic impedance.In the case of this RTC real time clock, there is 5V voltage supplied to it.A total of 44 pins are included in this product.RTCs belongs to M41T256 family.Keeping in mind that the supply voltage of this electrical digital time clock is 2.5V~3.5V is important.It is included as part of Timer or RTC.A memory of 32KB is embedded in the RTC times, which can be used to store programs and data.There should not be a frequency higher than 0.032MHz in the output.In this case, the RTC module has a mounting type of Surface Mount.For the purpose of powering the real time clock, the power supply is set to 5V.It is a type of real time clock belonging to the Timekeeper? series.
