    Features :
    + 24C32 32K I2C EEPROM Memory
    + DS1307 based RTC with LIR2032 battery
    + Backup by AT24C32 32Kbit
    + DS1307,AT24C32 can work separated
    + Leads to the DS1307 clock pin, to provide the clock signal for the microcontroller

    Datasheet:
    + DE4205-sample.zip
    + AT24C32.pdf
    + DS1307.pdf

    Pin out:
    1. DS (not used)
    2. SCL (I2C bus clock)
    3. SDA (I2C bus data)
    4. VCC (+5V)
    5. Ground.

    Note:
    + These units work well with Arduinos, it is as simple as connecting 4 wires, +V, ground, and the two I2C bus wires which gives access to both the real time clock and EEPROM.
    + The real time clock will not run unless initialised (It keeps it's data in RAM which can be cleared by removing the battery which also de initialises it).
