BQ4285LSTR Overview
In the SOIC package, real time clocks is embedded as a dependency.When a transmission line is terminated with 24 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 3.15V voltage at the moment.A total of 24 pins are equipped with the RTCs.The frequency of real time clocks' output should not exceed 0.032MHz.There are 24 pins on it.When an input signal is received, 1 timers are used to output a signal at a preset time.It reaches a maximum supply voltage of 3.6V (Vsup).In this electrical real time analog clock, uPs/uCs/peripheral ICs are of the type TIMER, REAL TIME CLOCK.In order to maintain normal operation, the supply voltage (Vsup) must be kept above 2.7V.Under 70°C, the operating temperature should be maintained.
