ISL12028IV27AZ-T Overview
There is a version of real time clocks in the package TSSOP.Transmission lines with 14 terminations have the characteristic impedance of the RTC module terminating them.This RTC real time clock is supplied with 3.3V voltage.The output frequency of this real time analog clock should not exceed 0.032MHz Hz.It appears that the RTC module's mounting type is Surface Mount.The power supply is 3/5V.With 14 pins, it is equipped.Maintaining a voltage of 3.3V will result in high efficiency.Over -40°C is the recommended operating temperature.RTC time is recommended that the operating temperature is lower than 85°C.With 2.7V as the minimum supply voltage, real time clocks operate.With a maximum voltage of 5.5V, real time clocks operate.
