ISL12027IBZ Overview
In package SOIC, real time clocks can be found.In this case, time clock is packaged in the way of Bulk.It is possible to terminate transmission lines with 8 terminations, which means that the RTC module terminating the line matches its characteristic impedance.This electronic component receives a voltage of 3.3V.A memory of 512B is embedded in the RTC times, which can be used to store programs and data.0.032MHz should be the maximum output frequency.A Surface Mount mounting type is assigned to the RTC module.For the purpose of powering the real time clock, the power supply is set to 3/5V.The real time clock is equipped with 8 pins.A high efficiency supply voltage should be maintained at 3.3V.-40°C is the minimum operating temperature.Operating temperatures should be below 85°C.In order for it to operate, real time clocks require a minimal supply voltage of 2.7V.The maximum voltage for the supply is 5.5V.
