DS17485E-3+ Overview
In package 28-TSSOP (0.465, 11.80mm Width), real time clocks can be found.Tray is the way in which time clock is packaged.This electrical RTC is powered by 2.7V~3.7V voltage.Electrical real time clocks of this type are Clock/Calendar.The way this real time clock (RTC) is mounted on the system board is Surface Mount.In order to be safe, electronic time clocks are imperative that the temperature are kept at 0°C~70°C at all times.Alarm, Daylight Savings, Leap Year, NVSRAM, Square Wave Output can be ensured when operating.In the case of 28 terminations, transmission lines have the characteristic impedance of the terminating RTC module.The supply voltage of this RTC real time clock is 3V.As it has 28 pins, it is equipped with the necessary features.The family to which RTCs belongs are DS17485.This electrical digital time clock has a supply voltage of 2.5V~3.7V.In Timer or RTC, this part is included.The RTC times have a memory size of 4KB that is available for storing data and programs.There should be no frequency greater than 0.032MHz in real time clocks' output.Mounting type for the RTC module is Surface Mount.For the purpose of powering the real time clock, the power supply is set to 3V.There are 28 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock. Following an input signal, there are 1 timers that output a signal at a preset time.High efficiency requires a 3V supply voltage.
