DS1339U-3 Overview
In the UMAX package, real time clocks is embedded as a dependency.8 terminations result in transmission lines having the characteristic impedance of a RTC module terminating them.3V voltage is present on this electronic component.A total of 8 pins are attached to this RTCs.Timer or RTC includes this part.The output frequency should not exceed 0.032MHz.A mounting type of Surface Mount has been specified for this RTC module.There is a power supply of 3V used to power the real time clock.There are 8 pins on it.Following an input signal, there are 1 timers that output a signal at a preset time.Maintaining the supply voltage at 3V is the key to high efficiency.Operating temperatures should be greater than -40°C.A temperature lower than 85°C should be used for operating.The minimal supply voltage is 2.7V.The maximal supply voltage is 3.3V.
