PCF2129AT/1,512 Overview


In the 20-SOIC (0.295, 7.50mm Width) package, real time clocks is embedded as a dependency.As you can see, time clock is packaged as if time clock were in the form of Tube.This electrical RTC is powered by a voltage that is 1.8V~4.2V at the time of installation.Electrical real time clock type Clock/Calendar.In this case, Surface Mount is the way this part is mounted on the systemboard.Maintaining a constant temperature of -40°C~85°C is essential for safe operation.Operating with Alarm, Leap Year, Square Wave Output, TCXO/Crystal, Watchdog Timer are possible.A transmission line can have a 20 termination by terminating it with a RTC module whose characteristic impedance matches the line's.The board is equipped with a total of 20 pins.There are only one family in which RTCs belongs, and that are PCF2129.Its supply voltage is 1.8V~4.2V.The content of Timers or RTCs includes this component.For the purpose of powering the real time clock, the power supply is set to 2/4V.
