Description
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. This is Tiny RTC Real Time Clock DS1307 I2C IIC Module for Arduino . It contains a DS1307 real-time clock IC .
It’s one of the easiest to use RTCs out there, with Arduino and other libraries or simply use I2C commands to set and retrieve the time and date. Along with the DS1307 real-time clock, the module also has an Atmel 24C32 EEPROM chip which is handy for storing data without worrying about power loss. There is also space on the board to solder your own DS18B20 temperature sensor.
DS1307 Real Time Clock module is used to track the current time and date. It is generally used in computers, laptops, mobiles, embedded system applications devices, etc. e. sensor values, GPS coordinates, etc. For getting timestamps, we need to use RTC (Real Time Clock). This module is based on the DS1307 IC from Dallas. 768 kHz clock. And supports I2C Interface. 768 kHz quartz crystal. 5pF. 768 kHz oscillator.
The output of the internal oscillator, X2 is drifted if an external oscillator is connected to X1. Pin 3 : Battery input for any standard 3V lithium cell or another energy source. 5V for suitable operation. 25 x VBAT nominal. A lithium battery with 48mAhr or greater will back up the DS1307 for more than 10 years in the absence of power at 25ºC.
UL is recognized to ensure against reverse charging current when utilized as part of conjunction with a lithium battery. Pin 4: Ground. Pin 5: Serial data input/output. 5V. Regardless of the voltage on VCC. Pin 6: Serial clock input. It is the I2C interface clock input and is used in data synchronization. Pin 7: Square wave/output driver.
When enabled, the SQWE bit set to 1, the SQW/OUT pin outputs one of four square-wave frequencies (1Hz, 4 kHz, 8 kHz, and 32 kHz). This is also an open drain and requires an external pull-up resistor. 5V and can be left floating, if not used. Pin 8: Primary power supply. When the voltage is applied within normal limits, the device is fully accessible and data can be written and read.
When a backup supply is connected to the device and VCC is below VTP, read and write are inhibited. However, at low voltages, the timekeeping function still functions.
