BQ3285ESSTR Overview
In package 24-SSOP (0.154, 3.90mm Width), real time clocks is located.The package is Tape & Reel (TR).It requires a voltage of 4.5V~5.5V to be supplied.This electrical real time clock is of type Clock/Calendar.Surface Mount is the way this real time clock (RTC) is mounted on the system board.The operating temperature should be 0°C~70°C.During operation, Alarm, Daylight Savings, Leap Year, NVSRAM, Square Wave Output can be guaranteed.When a transmission line is terminated with 24 terminations, it 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.With its 24 pins, it has the necessary functions.A voltage of 2.5V~4V is required for the supply of this electrical digital time clock.For storing data and programs, the RTC times embed a memory of 242B.In order for it to work properly, real time clocks' output frequency should not exceed 0.032MHz.1 timers are in the real time clock that outputs a signal in response to an input signal.
