DS1644P-120+ Product Details
DS1644P-120+ Overview
This can be found in the package 34-PowerCap™ Module.The package is Tube.This electrical RTC receives its power from the 4.5V~5.5V supply voltage.There is a type of electrical real time clock Clock/Calendar associated with this real time clock.Here, Surface Mount represents how this part is mounted.Temperature should be set at 0°C~70°C.In order to ensure Leap Year, NVSRAM when operating, a certain value has to be set.There is the possibility of terminating transmission lines with 34 terminations, which means that the equipment used to terminate the line will match its characteristic impedance.This RTC real time clock has a voltage of 5V.With 34 pins, it is equipped with the necessary functions.DS1644 are a family of objects that belongs to RTCs .There is a voltage of 3V when powering this electrical digital time clock.It should be noted that the RTC times embed a memory of 32KB which is usable for storing programs and data as well.Neither real time clocks' output frequency nor real time clocks' response frequency should exceed 0.032MHz.It operates from 5V power supplies.There are 34 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock.
