PT7C43390LEX Overview
A Tape & Reel (TR) package is used to package time clock.Transmission lines can be terminated with 8 terminations, which means that the RTC module that terminates the line matches its characteristic impedance.In this RTC real time clock, there is a voltage of 3V supplied to it.The power supply is 3/5V.1 timers are in the real time clock that outputs a signal in response to an input signal.It reaches 5.5V when the maximal supply voltage (Vsup) is reached.This electrical real time analog clock has TIMER, REAL TIME CLOCK for uPs/uCs/Peripheral ICs.For normal operation, Vsup must be above 1.3V.Temperatures should be kept below 85°C.
