    Bus Architecture

    I2C-bus parallel vs serialCommonly described as Two-wire bus

    One wire for data, one wire for clock

    Serial bus to conserve pins (versus parallel)

    Master-Slave hierarchy for simplicity

    Good for low to medium speed applications (< 1 MHz)

    Logic

    VCC

    I2C = Inter-IC Parallel

    Costs EMC, interconnects and pins

    Lot of programming

    Lots of wires

    Saves PCB space

    Easily expandable

    Better results, no hassle

    S = Start condition R = read (active high)

    A = Acknowledge A = Not Acknowledge

    P = Stop condition W = Write (active low)

    Write data

    Read data

    New devices can be

    easily clipped on to an existing bus!

    Each device is addressed individually by

    software with a unique address that can be

    modified by hardware pins.

    Open drain outputs provide for a wired-AND connection that allows devices to be

    added or removed without impact.

    The master always

    sends the SCL
