DS1388Z-33+T&R Overview
There is an embedded version of real time clocks in the package 8-SOIC (0.154, 3.90mm Width).This package has a package type of Tape & Reel (TR).Electrical RTCs such as this have a 2.97V~3.63V 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 EEPROM, Leap Year, Supervisor, Trickle-Charger, Watchdog Timer is ensured when operating, then the operation will be successful.There are a family named DS1388 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 512B that is available for storing programs as well as data.A total of 8 pins are equipped with the real time clock.Operating temperatures should be greater than -40°C.A temperature lower than 85°C should be used for operating.
