PCA2129T/Q900/2,51 Overview
In the 16-SOIC (0.295, 7.50mm Width) package, real time clocks is embedded.Tape & Reel (TR) is the way time clock is packaged.1.8V~4.2V is the supply voltage of this electrical RTC.Clock/Calendar is the type of this electrical real time clock.There is an real time clock (RTC) mounted in the way of Surface Mount.-40°C~85°C should be the operating temperature.Operating with Alarm, Leap Year, Square Wave Output, TCXO/Crystal, Watchdog Timer are possible.In 16 terminations, a transmission line is terminated with an impedance-matched RTC module.2V voltage is present on this electronic component.With 16 pins, it is equipped.The PCA2129 family contains RTCs .This electrical digital time clock has a supply voltage of 1.8V~4.2V.The output frequency should not exceed 0.032MHz.A total of 1.8/4.2V power supplies are required to operate it.An input signal is received by 1 timers, which output a signal after a preset time.
