M41T56C64MY6F Overview
In the 18-SOX, 18-SOIC with Crystal (7.5mm Width) package, real time clocks is embedded as a dependency.Tape & Reel (TR) is the package format.In this electrical RTC, the supply voltage is 4.5V~5.5V.Clock/Calendar is the type of electrical real time clock that is being used.As you can see from the diagram, this electronic component is mounted in the way of Surface Mount.There should be -40°C~85°C operating temperature.When operating, electronic time clocks are possible to ensure that EEPROM, Leap Year, NVSRAM are maintained.When a transmission line is terminated with 18 terminations, it means that the RTC module that terminates the line matches its characteristic impedance.It should be noted that this RTC real time clock is being supplied with 5V voltage at the moment.A total of 18 pins are equipped with the RTCs.The family in which RTCs belongs are M41T56.A voltage of 2.5V~3.5V is supplied to this electrical digital time clock.RTC times embed a memory of 56B 8KB for storing programs and data.The frequency of real time clocks' output should not exceed 0.032MHz.Mounting type Surface Mount is chosen for the RTC module.In order for it to be powered, it requires a power supply of 5V.There are 18 pins on it.Optimal efficiency can be achieved by maintaining the supply voltage at 5V.
