DS1284QN/T&R Overview
There is an embedded version in the package 28-LCC (J-Lead).Packaged as Tape & Reel (TR).This electrical RTC is powered by 4.5V~5.5V voltage.This electrical real time clock is of type Clock/Calendar.Surface Mount is the way to mount this real time clock (RTC).A temperature of -40°C~85°C should be used for operation.During operation, Alarm, Leap Year, Square Wave Output, SRAM, Watchdog Timer can be guaranteed.RTCs are a member of the family DS1284.Its supply voltage is 2.4V~3.5V.In these RTC times, there is a memory of 50B where data and programs can be stored.This RTC module has a mounting type of Surface Mount.28 pins are present on it.RTC time is recommended that the operating temperature be above -40°C.Lower than 85°C should be the operating temperature.There is minimum supply voltage of 4.5V required for real time clocks to operate.In this case, 5.5V is the maximum supply voltage.
