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.
DS1307 Specifications
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
The DS1307 operates as a slave device on the serial bus. Access is obtained by implementing a START condition and providing a device identification code followed by a register address. Subsequent registers can be accessed sequentially until a STOP condition is executed. The START and STOP conditions are generated using the low level drives, SEND_START and SEND_STOP found in the attached DS5000 code. Also the subroutines SEND_BYTE and READ_BYTE provide the 2-wire handshaking required for writing and reading 8-bit words to and from the DS1307.
