What is RTC module DS1307?
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. The end date of each month is automatically adjusted, especially for months with less than 31 days.
How do I reset my RTC DS1307?
So to start, remove the battery from the holder while the Arduino is not powered or plugged into USB. Wait 3 seconds and then replace the battery. This resets the RTC chip.
What is DS1307 clock?
Maxim Integrated DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. The clock/calendar on the DS1307 provides seconds, minutes, hours, day, date, month, and year information.
What is the use of RTC?
A real-time clock (RTC) is an IC that keeps an updated track of the current time. This information can be read by a microprocessor, usually over a serial interface to facilitate the software performing functions that are time dependent.
Does RTC work without battery?
The DS1302 real-time clock (RTC) works very much like a watch. The RTC module accurately keeps time with a precise oscillator and is maintained with a small battery (not included).
Whats is RTC?
A real-time clock (RTC) is a computer clock, usually in the form of an integrated circuit that is solely built for keeping time. RTCs can be found running in personal computers, embedded systems and servers, and are present in any electronic device that may require accurate time keeping.
How does the DS1307 RTC chip work?
The DS1307 RTC chip is a low power, full binary-coded decimal (BCD) clock/calendar RTC (Real Time Clock) IC with 56 bytes of SVRAM that communicates through I2C Protocol. The DS1307 is 8 pin IC. The IC is operated on low power consumption when it operated on a battery then it consumes less than 500 nA power.
Is the DS1307 an I2C real time clock?
DS1307 I2C Real Time Clock (RTC) The DS1307 is a low power Full Binary (BCD) Real Time Clock (RTC) IC with 56 bytes of SVRAM that communicates through I2C Protocol. The IC can work from directly supply on Vcc and switch to Battery automatically when required.
What are the pins on a DS1307 clock?
Pin Description of DS1307: Pin 1, 2: Connections for standard 32.768 kHz quartz crystal. The internal oscillator circuitry is intended for operation with a crystal having a specified load capacitance of 12.5pF. X1 is the input to the oscillator and can alternatively be connected to an external 32.768 kHz oscillator.
Is the DS1307 IC 5V or 5V?
The DS1307 is a 8-pin IC which operates on 5V and communicates with CPU though I2C protocol. A typical application circuit for the DS1307 from DS1307 datasheet is shown below. As you can see the IC has SCL (Serial Clock) and SDA (Serial Data) pins using which it communicates to the CPU, both these pins has to be pulled high using a resistor.
