X1288V14-2.7T1 Overview
This RTC real time clock has a voltage supply of 5V which is provided to it.A total of 14 pins are attached to this RTCs.Ensure that the output frequency does not exceed 0.032MHz.As a power supply for the real time clock, a value of 3/5V is used.Following an input signal, there are 1 timers that output a signal at a preset time.As soon as the maximum supply voltage (Vsup) of 5.5V is reached, the circuit is off.The type of uPs/uCs/peripheral ICs in this electrical real time analog clock is TIMER, REAL TIME CLOCK.Normal operation requires a supply voltage (Vsup) greater than 2.7V.It is recommended that the operating temperature be kept below 70°C.
