PCF8523TS/1,112 Overview
In the 14-TSSOP (0.173, 4.40mm Width) package, real time clocks is embedded as a dependency.Tube is the package format.In this electrical RTC, the supply voltage is 1.6V~5.5V.Clock/Calendar is the type of electrical real time clock that is being used.As you can see from the diagram, this electronic component is mounted in the way of Surface Mount.There should be -40°C~85°C operating temperature.When operating, electronic time clocks are possible to ensure that Alarm, Leap Year, Watchdog Timer are maintained.When a transmission line is terminated with 14 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 3V voltage at the moment.A total of 14 pins are equipped with the RTCs.The family in which RTCs belongs are PCF8523.A voltage of 1.8V~5.5V is supplied to this electrical digital time clock.The frequency of real time clocks' output should not exceed 0.032MHz.In order for it to be powered, it requires a power supply of 1.2/5.5V.When an input signal is received, 1 timers are used to output a signal at a preset time.
