PCF2129AT/2,518 Overview
The package 20-SOIC (0.295, 7.50mm Width) contains real time clocks.A Tape & Reel (TR) package is used to package time clock.Its supply voltage is 1.8V~4.2V.It can be said that this electrical real time clock belongs to the Clock/Calendar type.Surface Mount is the way this real time clock (RTC) is mounted.A temperature of -40°C~85°C should be used for operation.When operating, electronic time clocks are possible to ensure that Alarm, Leap Year, Square Wave Output, TCXO/Crystal, Watchdog Timer are maintained.With 20 terminations, transmission lines have the characteristic impedance of the RTC module terminating them.A voltage of 3.3V is applied to this electronic component.20 pins are present on it.The family to which RTCs belongs are PCF2129.Note that the supply voltage is 1.8V~4.2V for this electrical digital time clock.In Timers or RTCs, you can find this component.There is a power supply of 2/4V used to power the real time clock.1 timers are control real time clocks that emits a signal after receiving an input signal at a predetermined time.
