BQ3285ESTR Product Details

BQ3285ESTR Overview


You can find real time clocks in package 24-SOIC (0.295, 7.50mm Width) among the other packages that are available.Tape & Reel (TR) is the way time clock is packaged, which is the way time clock is intended to be.It requires a voltage of 4.5V~5.5V to be supplied.Electrical real time clocks of type Clock/Calendar are involved.This electronic component has been mounted in the way of Surface Mount.In order to be safe, electronic time clocks are imperative that the temperature are kept at 0°C~70°C at all times.When a command are executed, electronic time clocks are possible to maintain Alarm, Daylight Savings, Leap Year, NVSRAM, Square Wave Output in order to maintain the current state.A transmission line with 24 terminations possesses the characteristic impedance of the RTC module terminating it.RTC real time clocks like this have a 5V supply voltage.The RTCs are equipped with the necessary features due to its 24 pins.As far as the family are concerned, RTCs are part of BQ3285.This electrical digital time clock's supply voltage is 2.5V~4V.In the real time analog clocks, the available memory size is 242B.The frequency of real time clocks' output should not be higher than 0.032MHz.The RTC module is mounted with mounting type Surface Mount.As a power supply for the real time clock, a value of 5V is used.A total of 24 pins are equipped with the real time clock.Following an input signal, there are 1 timers that output a signal at a preset time.RTC time is essential that the supply voltage remain at 5V for maximum efficiency.
