DS14285Q+ Overview
In the 28-LCC (J-Lead) package, real time clocks is embedded.Time clock is packaged in the way of Tube.There is 4.5V~5.5V voltage supply for this electrical RTC.An electrical real time clock of this type is called a Clock/Calendar.Here, Surface Mount represents how this part is mounted.Maintaining a constant temperature of 0°C~70°C is essential for safe operation.As long as Alarm, Daylight Savings, Leap Year, NVSRAM, Square Wave Output is ensured when operating, the system will work properly.Transmission lines with 28 terminations have the characteristic impedance of their termination RTC modules.A voltage of 5V is applied to this electronic component.There are 28 pins on it.In the family DS14285, RTCs are a member.There is 2.5V~3.6V supply voltage for this electrical digital time clock.There is a component of this type in Timer or RTC.In the RTC times, there is a memory of 114B that is available for storing programs as well as data.A maximum output frequency of 0.032MHz should be maintained by the real time analog clock.As a power supply for the real time clock, a value of 5V is used.In this system, there are 1 timers, which are real time clocks that output a signal at a preset time after an input signal is received.
