DS1307 IC RTC Real Time Clock 64X8 Serial Real-Time Clock

DS1307 IC also known as RTC IC 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 I2 C, bidirectional bus.

The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year.

The clock operates in either the 24-hour or 12- hour format with AM/PM indicator.

IC RTC DS1307 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. Timekeeping operation continues while the part operates from the backup supply.

RTC IC DS1307 Real time clocks (RTC), as the name recommends are clock modules. IC 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.

They are available as integrated circuits (ICs) and supervise timing like a clock and also operate date like a calendar.

The main advantage of IC RTC DS1307 is that they have an arrangement of battery backup which keeps the clock/calendar running even if there is power failure.

An exceptionally little current is required for keeping the RTC animated. We can find these RTCs in many applications like embedded systems and computer mother boards, etc.

Two inputs X1 and X2 are connected to a 32.768 kHz crystal oscillator as the source for the chip. VBAT is connected to positive culture of a 3V battery chip. Vcc power to the I2C interface is 5V and can be given using microcontrollers.
