DS1340Z-3+T&R Product Details

DS1340Z-3+T&R Overview


real time clocks is located in package 8-SOIC (0.154, 3.90mm Width).As of Tape & Reel (TR), time clock is packaged in this way.There is 2.7V~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, Leap Year, Trickle-Charger can be ensured.DS1340 are the family name of RTCs .As far as the supply voltage for this electrical digital time clock is concerned, it is 1.3V~3.7V.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 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 2.7V, real time clocks are capable of operating.This real time clock operates with a max supply voltage of 3.3V.
