In the 20-SOIC (0.295, 7.50mm Width) package, real time clocks is embedded.Tube is the way time clock is packaged.3V~6V 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, Watchdog Timer are possible.In 20 terminations, a transmission line is terminated with an impedance-matched RTC module.5V voltage is present on this electronic component.This electrical digital time clock has a supply voltage of 2.2V~6V.A memory of 32B can be used to store data and programs.The output frequency should not exceed 2.1MHz.An input signal is received by 1 timers, which output a signal after a preset time.
