BQ4802LYDW Overview
There is an embedded version in the package 28-SOIC (0.295, 7.50mm Width).Packaged as Tube.This electrical RTC is powered by 2.7V~3.6V voltage.This electrical real time clock is of type Clock/Calendar.Surface Mount is the way to mount this real time clock (RTC).A temperature of 0°C~70°C should be used for operation.During operation, Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer can be guaranteed.The 28 termination is the practice of terminating a transmission line with a RTC module matched to its characteristic impedance.It is possible to see 3.3V voltage being supplied to this RTC real time clock.28 pins are attached to it.RTCs are a member of the family BQ4802.Its supply voltage is 2.4V~4V.There should be no more than 0.032MHz frequency in real time clocks' output.This RTC module has a mounting type of Surface Mount.28 pins are present on it.In this system, there are 1 timers, which are real time clocks that output a signal at a preset time after an input signal is received.RTC time is important to maintain the supply voltage at 3.3V in order to maintain high efficiency.The real time analog clock has 8 outputs configured.
