What is a DS1307 RTC module?
GENERAL DESCRIPTION. The DS1307 serial real-time clock (RTC) is a low- power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I2C, bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information.
What is address of DS1307?
The address byte contains the 7 bit DS1307 address, which is 1101000, followed by the *direction bit (R/W ) which, for a write, is a 0. After receiving and decoding the address byte the device outputs an acknowledge on the SDA line.

What is DS1307 used for?
Real time clocks (RTC), as the name recommends are clock modules. The DS1307 real time clock (RTC) IC is an 8 pin device using an I2C interface. The DS1307 is a low-power clock/calendar with 56 bytes of battery backup SRAM. The clock/calendar provides seconds, minutes, hours, day, date, month and year qualified data.
How long does a RTC battery last?
3 years
The memory battery (aka motherboard, CMOS, real-time clock (RTC), clock battery) is generally a CR2032 lithium coin cell. This cell battery has an estimated life of 3 years when power supply unit (PSU) is unplugged or when the PSU power switch is turned off.
What’s the difference between DS1307 and ds132 RTC?
Aside from I2C support, are there any serious differences between the DS1307 RTC that comes installed on the PDB and the DS1302 that people keep talking about?
What’s the difference between DS1307 and ds3231 real time clocks?
There are two main differences between the ICs on the real-time clock modules, which is the accuracy of the time-keeping. The DS1307 used in the first module works very well, however the external temperature can affect the frequency of the oscillator circuit which drives the DS1307’s internal counter.
Which is RTC chip does Arduino interface with?
DS1307 RTC chip. At the heart of the module is a low-cost, quite accurate RTC chip from Maxim – DS1307. It manages all timekeeping functions and features a simple two-wire I2C interface which can be easily interfaced with any microcontroller of your choice. The chip maintains seconds, minutes, hours, day, date, month, and year information.
How does the Arduino work with the DS1307?
Button B1 selects the parameter and B2 increments the selected parameter. The Arduino code below doesn’t use any library for the DS1307 RTC, the Wire library is for the communication between the Arduino and the DS1307 using I2C protocol.
