DS1688S+ Overview
In the 28-SOIC (0.295, 7.50mm Width) package, real time clocks is embedded.Time clock is packaged in the way of Tube.In this electrical RTC, the supply voltage is 2.7V~3.3V 4.5V~5.5V.The type of this electrical real time clock is Clock/Calendar.The position of this real time clock (RTC) on the system board is indicated by Surface Mount.Maintaining a constant temperature of 0°C~70°C is essential for safe operation.During operation, the value of Alarm, Leap Year, Square Wave Output, Unique ID can be ensured.There are 28 terminations, which are the practice of ending a transmission line welectronic time clocksh a RTC module that matches the characteristic impedance of the line.Its supply voltage is 3V.28 pins are attached to it.The family RTCs belongs to are DS1688.Programs and data can be stored in the 114B memory embedded in the RTC times.The output frequency of this real time analog clock should not exceed 0.032MHz Hz.There are 1 timers, which are control real time clocks that output a signal at a preset time after an input signal is received.The CAN ALSO OPERATE WITH 5V SUPPLY characteristics are also present.There are 16 bits in this digital time clock.
