BQ4822YMA-70 Overview
There is an embedded version of real time clocks in the package 28-DIP Module (0.61, 15.49mm).A Tray package is used to package time clock.Its supply voltage is 4.5V~5.5V.Electrical real time clocks of type Clock/Calendar are involved.A part of this electronic RTC module is mounted in the way of Through Hole.Temperature should be set at 0°C~70°C.If Alarm, Leap Year, Supervisor, Watchdog Timer is ensured during operation, then there is no problem.When transmission lines are terminated with a zero, their characteristic impedance is that of the terminating RTC module.In this case, the voltage supplied to the electronic component is 5V.There are 28 pins on it.The family RTCs belongs to are BQ4822.It is included as part of Timer or RTC.In the RTC times you will find a memory of 7.8kB which is available for your programs and data storage.A frequency of 0.032MHz should not be exceeded by real time clocks' output frequency.The mounting type of the RTC module is Through Hole.For powering the real time clock, a power supply with a voltage of 5V is used.A total of 28 pins are attached to this real time clock.RTC time is important to maintain the supply voltage at 5V in order to maintain high efficiency.
