consumer and telecommunications products, as a control, diagnostics and power management bus.
Multiple matches I 2 C bus standard devices can communicate via the same I 2 C bus, without the
need to address decoder.
I 2 C bus require only the two signal lines, a serial data line SDA, the other is a serial clock
line SCL. I 2 C bus devices generally have their SDA and SCL pins are open-drain (or open
collector) output structure. Therefore, actual use, SDA Figure 4: AM2320 wiring diagram and SCL
signal lines must add pull-up resistors (Rp, Pull-Up Resistor). Value pull-up resistor is generally 3 ~
10 kΩ. Therefore, when the bus is idle, the two signal lines remain high, almost no current
consumption; electrical compatibility, and supports a variety of different voltage logic device
interfaces; may be directly connected between the two buses, not require additional conversion
circuitry to support a variety of communication more from a major is the most common means of
communication. It also supports dual-host communication, multi host communication and
broadcast mode, etc.
I 2 C typical configuration shown in Figure 5.

8.1.3 I 2 C bus protocol specification
I 2 C Bus Definition of Terms
I 2 C bus connection via the serial data (SDA) and serial clock (SCL) lines on the bus, so that
each device to transmit information between the device has a unique address recognition, and can be
used as a transmitter or receiver (the device's functions decision), the device when performing data
transfers can also be seen as a master or slave, the master is initialized data transmission device
allows the transmission bus and generates a clock signal. At this time, any device addressed is
considered a slave. I 2 C bus terms are defined in detail in Table 5.
I 2 C-bus transfer rate
I 2 C bus communication rate controlled by the host, to fast to slow. However, the maximum rate
is limited, the transfer rate on a I 2 C bus data in standard mode speeds up to 100Kb / s.
I 2 C Bus bit transmission
I 2 C bus bit transmitted through the data line SDA and SCL clock line two lines together to
complete. During high clock line SCL and SDA data line represents the current transmission is low
