DS1305E+ Overview
This can be found in the package 20-TSSOP (0.173, 4.40mm Width).The package is Tube.This electrical RTC receives its power from the 2V~5.5V supply voltage.There is a type of electrical real time clock Clock/Calendar associated with this real time clock.Here, Surface Mount represents how this part is mounted.Temperature should be set at 0°C~70°C.In order to ensure Alarm, Leap Year, NVSRAM, Trickle-Charger when operating, a certain value has to be set.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.This RTC real time clock has a voltage of 5V.With 20 pins, it is equipped with the necessary functions.DS1305 are a family of objects that belongs to RTCs .There is a voltage of 2V~5.5V when powering this electrical digital time clock.It should be noted that the RTC times embed a memory of 96B which is usable for storing programs and data as well.This RTC module is mounted using type Surface Mount.There are 20 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock. The frequency that can be achieved is 32.8kHz.It is configured with 1 outputs.
