DS1305EN+ Overview
A package named 20-TSSOP (0.173, 4.40mm Width) contains real time clocks.Tube is the packaging method.There is 2V~5.5V supply voltage for this electrical RTC.Electrical real time clocks of this type are Clock/Calendar.real time clock (RTC)s like this are mounted in the way of Surface Mount.-40°C~85°C is the operating temperature.When operating, you can ensure Alarm, Leap Year, NVSRAM, Trickle-Charger.A transmission line can have a 20 termination by terminating it with a RTC module whose characteristic impedance matches the line's.In the case of this RTC real time clock, there is 5V voltage supplied to it.The RTCs are equipped with 20 pins.DS1305 is the family name of this object.This electrical digital time clock is powered by 2V~5.5V voltage.Programs and data can be stored in the 96B memory embedded in the RTC times.Mounting type for the RTC module is Surface Mount.20 pins are attached to it.There is 32.768kHz frequency that can be achieved.A total of 1 outputs have been configured.
