DS1673S-3 Product Details

DS1673S-3 Overview


In package 20-SOIC (0.295, 7.50mm Width), real time clocks can be found.In this case, time clock is packaged in the way of Tube.A voltage of 2.7V~3.3V is supplied to this electrical RTC.Electrical real time clock type Portable System Controller.There is an electronic component mounted in the way of Surface Mount.Ideally, the operating temperature should be 0°C~70°C.During operation, the value of Alarm, Leap Year, Watchdog Timer can be ensured.It is possible to terminate transmission lines with 20 terminations, which means that the RTC module terminating the line matches its characteristic impedance.This electronic component receives a voltage of 3V.There are 20 pins on it.There is 2.5V~3.7V supply voltage for this electrical digital time clock.0.032MHz should be the maximum output frequency.Also, 3-CHANNEL, 8-BIT ADC characterize it.
