SMBus/I 2 C-Compatible Serial Interface
The MAX6884/MAX6885 feature an I 2 C/SMBus-compati-
ble 2-wire serial interface consisting of a serial data line
(SDA) and a serial clock line (SCL). SDA and SCL facili-
tate bidirectional communication between the
MAX6884/MAX6885 and the master device at clock
rates up to 400kHz. Figure 6 shows the 2-wire interface
timing diagram. The MAX6884/MAX6885 are transmit/
receive slave-only devices, 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 MAX6884/
MAX6885 by transmitting the proper address followed by
command and/or data words. Each transmit sequence is
SDA
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 an open-drain
input/output. SCL and SDA both require external pullup
resistors to generate the logic-high voltage. Use 4.7k ?
resistors for most applications.
Bit Transfer
Each clock pulse transfers one data bit. The data on
SDA must remain stable while SCL is high (see Figure
7), otherwise the MAX6884/MAX6885 register a START
or STOP condition (see Figure 8) from the master. SDA
and SCL idle high when the bus is not busy.
