DS1501WE+T&R Overview


In package 28-TSSOP (0.465, 11.80mm Width), real time clocks is located.Basically, time clock is packaged in a way that is equivalent to Tape & Reel (TR).This electrical RTC has a supply voltage of 3V~3.6V.An electrical real time clock of this type is called a Clock/Calendar.Surface Mount is the way this real time clock (RTC) is mounted on the system board.As far as the operating temperature are concerned, electronic time clocks should be 0°C~70°C.When operating, electronic time clocks would be possible to ensure that the value Alarm, Leap Year, NVSRAM, Square Wave Output, Watchdog Timer, Y2K are maintained.RTCs belongs to DS1501 family.This electrical digital time clock is powered by a voltage that is 2.5V~3.7V at the time of installation.The RTC times embed a memory of 256B available for storing programs and data.A Surface Mount mounting type is assigned to the RTC module.28 pins are present on it.The supply voltage should be maintained at 3.3V for high efficiency.RTC time is advisable to operate at a temperature above 0°C.Ideally, the operating temperature should be lower than 70°C.A minimum supply voltage of 3V is required to operate real time clocks.Real time clocks operate with the maximal supply voltage of 3.6V.
