DS1677E Overview
Among the packages 20-TSSOP (0.173, 4.40mm Width) is where real time clocks can be found.In this case, time clock is packaged in the way of Tube.There is 4.5V~5.5V supply voltage for this electrical RTC.Electrical real time clocks of type Portable System Controller are involved.Surface Mount is the way to mount this real time clock (RTC).Electronic time clocks are recommended to operate at a temperature of 0°C~70°C.When operating, Alarm, Leap Year, Watchdog Timer can be ensured.20 terminations result in transmission lines having the characteristic impedance of a RTC module terminating them.It should be noted that this RTC real time clock is being supplied with 5V voltage at the moment.A total of 20 pins are attached to this RTCs.This electrical digital time clock has a 2.5V~3.7V supply voltage.The frequency of real time clocks' output should not be higher than 0.032MHz.The 3-CHANNEL, 8-BIT ADC characteristics are also present.
