DS1643P-85+ Overview
In package 34-PowerCap™ Module, 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 Clock/Calendar.There is an electronic component mounted in the way of Surface Mount.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 34 terminations, which means that the RTC module terminating the line matches its characteristic impedance.This electronic component receives a voltage of 5V.There are 34 pins on it.This object belongs to the family DS1643.There is 3V supply voltage for this electrical digital time clock.A memory of 8KB 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.The real time clock is equipped with 34 pins.A high efficiency supply voltage should be maintained at 5V.
