DS1306EN+T&R Product Details

DS1306EN+T&R Overview


real time clocks is located in package 20-TSSOP (0.173, 4.40mm Width).As of Tape & Reel (TR), 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, NVSRAM, Square Wave Output, Trickle-Charger can be ensured.DS1306 are the family name of RTCs .As far as the supply voltage for this electrical digital time clock is concerned, it is 2V~5.5V.For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 96B.Mounting type Surface Mount matches the RTC module.A total of 20 pins are attached to this real time clock.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.
