RTC registers are located in address locations from 00h to 0Fh and RAM memory registers are located in address locations from 08h wwith as shown in figure. This device operated with 1. Hi Sravanthi I sincerely appreciate your kind response regarding my article.

The standard quartz crystal frequency is SCL is a serial clock pin and it is used to synchronize data on serial interface. He has 8 years of experience in Customer Support, Operations and Administration. After completion of write operation in the slave device, microcontroller sends stop condition to the slave device. Every dependent device must comprise of rtc ds1307 interfacing with 8051 address to denote on it.

These registers are used to run calendar rtc ds1307 interfacing with 8051 and time of the day and displays the weekends. It is used to enable and disable interrupts. The control status register1 used to enable the RTC device. First, we will see the internals of DS and later how to read and write the date and time.

Below image shows the pin diagram and the recommended connections for DS So, we have connected externally via a serial communication for confirming the comprising data. The I2C bus protocol lets many dependent devices at a time. This register address is mainly used to let the control status registers. I2C bus protocol allows many slave devices at a time.

We should pass the actual time details as parameters.

This register used to activate the RTC device. In our wtih, we are using DS in 24 hour mode and we then convert it into 12 hour mode at the software side.

The actual format is like setTime sec,min,hour,dow,dom,month,year. RTC Interfacing with Microcontroller.

RAM memory registers are also located at 08h to 3Fh locations. Battery power source must be held between 2V to 3. Furthermore, any doubts regarding this concept, or basic electrical or electronic components for projects please give your feedback by commenting in the comment section below.
