DS1308U-33+T Overview
There is an embedded version of real time clocks in the package 8-TSSOP, 8-MSOP (0.118, 3.00mm Width).This package has a package type of Tape & Reel (TR).Electrical RTCs such as this have a 3V~5.5V supply.In this case, we are dealing with an electrical real time clock that has a type of Clock/Calendar.It should be noted that the real time clock (RTC) is mounted in the way of Surface Mount.Electronic time clocks are recommended to operate at a temperature of -40°C~85°C.If Leap Year, NVSRAM, Square Wave Output is ensured when operating, then the operation will be successful.There are 8 terminations for transmission lines, which means that the RTC module that terminates the line matches its characteristic impedance.This RTC real time clock has a voltage supply of 3.3V which is provided to it.There are a family named DS1308 that consarets of the RTCs .In this electrical digital time clock, the supply voltage is 1.3V~5.5V.In the RTC times, there is a memory of 56B that is available for storing programs as well as data.In this case, the RTC module is mounted in the way of Surface Mount.As a power supply for the real time clock, a value of 3.3/5V is used.A total of 8 pins are equipped with the real time clock.Following an input signal, there are 1 timers that output a signal at a preset time.RTC time is essential that the supply voltage remain at 3.3V for maximum efficiency.
