DS1244Y-70+ Product Details
DS1244Y-70+ Overview
In package 28-DIP Module (0.600, 15.24mm), real time clocks can be found.In this case, time clock is packaged in the way of Tube.A voltage of 4.5V~5.5V is supplied to this electrical RTC.Electrical real time clock type Phantom Time Chip.There is an electronic component mounted in the way of Through Hole.Ideally, the operating temperature should be 0°C~70°C.During operation, the value of Leap Year, NVSRAM can be ensured.It is possible to terminate transmission lines with 28 terminations, which means that the RTC module terminating the line matches its characteristic impedance.This electronic component receives a voltage of 5V.There are 28 pins on it.This object belongs to the family DS1244.A memory of 32KB is embedded in the RTC times, which can be used to store programs and data.A Through Hole mounting type is assigned to the RTC module.For the purpose of powering the real time clock, the power supply is set to 5V.The real time clock is equipped with 28 pins.A high efficiency supply voltage should be maintained at 5V.You can achieve 70GHz frequency.
