DS1347T+T&R Overview
real time clocks is located in package 8-WDFN Exposed Pad.As of Digi-Reel®, time clock is packaged in this way.There is 2V~5.5V voltage supply for this electrical RTC.It can be said that this electrical real time clock belongs to the Clock/Calendar type.The real time clock (RTC) that is mounted in the way of Surface Mount is connected to this circuit board.In order to operate properly, the temperature should be -40°C~85°C.During the course of operation, Alarm, Leap Year, SRAM can be ensured.DS1347 are the family name of RTCs .Mounting type Surface Mount matches the RTC module.A total of 8 pins are attached to this real time clock.Maintaining the supply voltage at 3.3V is the key to high efficiency.RTC time is advisable to operate at a temperature above -40°C.85°C is the optimal operating temperature.With the minimal voltage of 2V, real time clocks are capable of operating.This real time clock operates with a max supply voltage of 5.5V.
