DS1501WZ+T&R Overview
There is an embedded version in the package 28-SOIC (0.295, 7.50mm Width).Packaged as Tape & Reel (TR).This electrical RTC is powered by 3V~3.6V 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 0°C~70°C should be used for operation.During operation, Alarm, Leap Year, NVSRAM, Square Wave Output, Watchdog Timer, Y2K can be guaranteed.RTCs are a member of the family DS1501.Its supply voltage is 2.5V~3.7V.In these RTC times, there is a memory of 256B 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 important to maintain the supply voltage at 3.3V in order to maintain high efficiency.RTC time is recommended that the operating temperature be above 0°C.Lower than 70°C should be the operating temperature.There is minimum supply voltage of 3V required for real time clocks to operate.In this case, 3.6V is the maximum supply voltage.
