DS1670E+ Product Details

DS1670E+ Overview


real time clocks is located in package 20-TSSOP (0.173, 4.40mm Width).As of Tube, time clock is packaged in this way.There is 2.97V~3.63V voltage supply for this electrical RTC.It can be said that this electrical real time clock belongs to the Portable System Controller type.The real time clock (RTC) that is mounted in the way of Surface Mount is connected to this circuit board.In order to operate properly, the temperature should be 0°C~70°C.During the course of operation, Alarm, Leap Year, Watchdog Timer can be ensured.There is the possibility of terminating transmission lines with 20 terminations, which means that the equipment used to terminate the line will match its characteristic impedance.In this case, the voltage supplied to the electronic component is 3.3V.A total of 20 pins are included in this product.DS1670 are the family name of RTCs .As far as the supply voltage for this electrical digital time clock is concerned, it is 2.5V~3.7V.Mounting type Surface Mount matches the RTC module.A total of 20 pins are attached to this real time clock.Maintaining the supply voltage at 3.3V is the key to high efficiency.Additionally, it has the property of 3-CHANNEL, 8-BIT ADC.There is a frequency of 32.768kHz that can be achieved.With 1 outputs, the real time analog clock is configured.
