DS1307 Real Time Clock Module (RTC)

DS1307 Real Time Clock Module (RTC) 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. The end date of each month is automatically adjusted, especially for months with less than 31 days. Pin Configurations: Pin Number Pin ?Name Description 1,2 X1 , X2 Crystal Oscillator should be connected to these pins 3 V-Bat Connected to Positive terminal of the battery 4 Ground Ground pin of the IC 5,6 SCL and SDA Pins for I2C communication with CPU 7 SQW / Out Square wave output driver pin to obtain square wave frequencies. 8 Vcc Powers the IC typically 5V Features: I2C Interface RTC IC Operating Voltage: 5V Less than 500nA current when operating with battery 56bytes SVRAM Operates in power or battery mode Programmable square wave output pin Available in PDIP and SO package Applications: Robotics Gaming Servers Computer Peripherals GPS Utility power meters Package Includes: 1x RTC DS1307 Real-Time Clock Module 1x CR2032 Battery Datasheet: DS1307 Real Time Clock Module Related Products: SENSORS | MODULES
