SMBus/I2C-Compatible Serial Interface
The MAX6872/MAX6873 feature an I2C/SMBus-compati-
ble serial interface consisting of a serial data line (SDA)
and a serial clock line (SCL). SDA and SCL allow bidirec-
tional communication between the MAX6872/MAX6873
and the master device at clock rates up to 400kHz. Figure
2
shows
the
interface
timing
diagram.
The
MAX6872/MAX6873 are transmit/receive slave-only
devices, relying upon a master device to generate a
clock signal. The master device (typically a microcon-
troller) initiates data transfer on the bus and generates
SCL to permit that transfer.
A master device communicates to the MAX6872/
MAX6873 by transmitting the proper address followed by
command and/or data words. Each transmit sequence is
framed by a START (S) or REPEATED START (SR) condi-
tion 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 4.7k
for most applications.
Bit Transfer
Each clock pulse transfers one data bit. The data on
SDA must remain stable while SCL is high (Figure 3),
otherwise the MAX6872/MAX6873 register a START or
STOP condition (Figure 4) from the master. SDA and
SCL idle high when the bus is not busy.
