I
2
C Serial Interface
The device features an I
2
C-compatible serial interface
consisting of a serial data line (SDA) and a serial clock
line (SCL). SDA and SCL allow bidirectional communica-
tion between the device and the master device at clock
rates from 100kHz to 400kHz. The I
2
C bus can have
several devices (e.g., more than one device, or other I
2
C
devices in addition to the device) attached simultane-
ously. The A0 and A1 inputs set one of nine possible I
2
C
addresses (see Table 53).
The 2-wire communication is fully compatible with exist-
ing 2-wire serial interface systems; Figure 4 shows
the interface timing diagram. The device is a transmit/
receive slave-only device, relying upon a master device
to generate a clock signal. The master device (typically
a microcontroller) initiates data transfer on the bus and
generates SCL to permit that transfer.
A master device communicates to the device by trans-
mitting the proper address followed by command and/
or data words. Each transmit sequence is framed by
a START (S) or Repeated START (SR) condition and a
STOP (P) condition. Each word transmitted over the bus
is 8 bits long and is always followed by an acknowledge
pulse.
SCL is a logic input, while SDA is a logic input/open-
drain output. SCL and SDA both require external pullup
resistors to generate the logic-high voltage. Use 4.7kI
for most applications.
