DS1689S+T&R Overview
In package 28-SOIC (0.295, 7.50mm Width), real time clocks can be found.Tape & Reel (TR) is the way in which time clock is packaged.This electrical RTC receives its power from the 2.7V~3.3V 4.5V~5.5V supply voltage.It is a Clock/Calendar type electrical real time clock.This part is mounted on the systemboard in Surface Mount mode.Electronic time clocks are recommended to operate at a temperature of 0°C~70°C.During operation, the value of NVSRAM can be ensured.DS1689 are the family RTCs belongs to.This electrical digital time clock has a 2.5V~3.7V supply voltage.For storing data and programs, the RTC times embed a memory of 114B.A mounting type of Surface Mount has been specified for this RTC module.There are 28 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock. A temperature higher than 0°C is ideal for operating.Operating temperatures should be below 70°C.With the minimal voltage of 2.7V, real time clocks are capable of operating.The maximal supply voltage is 5.5V.
