10-Port I/O Expander with LED Intensity

Control and Interrupt

The MAX7316 SDA line operates as both an input and

Serial Interface

an open-drain output. A pullup resistor, typically 4.7k ,

is required on SDA. The MAX7316 SCL line operates

only as an input. A pullup resistor, typically 4.7k , is

required on SCL if there are multiple masters on the 2-

wire interface, or if the master in a single-master system

has an open-drain SCL output.

Serial Addressing

The MAX7316 operates as a slave that sends and

receives data through an I²C-compatible 2-wire inter-

face. The interface uses a serial data line (SDA) and a

serial clock line (SCL) to achieve bidirectional commu-

nication between master(s) and slave(s). A master (typ-

ically a microcontroller) initiates all data transfers to and

from the MAX7316 and generates the SCL clock that

synchronizes the data transfer (Figure 2).

Each transmission consists of a START condition

(Figure 3) sent by a master, followed by the MAX7316

7-bit slave address plus R/W bit, a register address

byte, one or more data bytes, and finally a STOP condi-

tion (Figure 3).

Start and Stop Conditions

Both SCL and SDA remain high when the interface is

not busy. A master signals the beginning of a transmis-

sion with a START (S) condition by transitioning SDA

from high to low while SCL is high. When the master

has finished communicating with the slave, it issues a

STOP (P) condition by transitioning SDA from low to

high while SCL is high. The bus is then free for another

transmission (Figure 3).

Bit Transfer

One data bit is transferred during each clock pulse.

The data on SDA must remain stable while SCL is high

(Figure 4).

SDA

Acknowledge

The acknowledge bit is a clocked 9th bit that the recipi-

ent uses to handshake receipt of each byte of data

(Figure 5). Thus, each byte transferred effectively

requires 9 bits. The master generates the 9th clock

pulse, and the recipient pulls down SDA during the

acknowledge clock pulse so the SDA line is stable low

during the high period of the clock pulse. When the

master is transmitting to the MAX7316, the device gen-

erates the acknowledge bit because the MAX7316 is

the recipient. When the MAX7316 is transmitting to the

master, the master generates the acknowledge bit

because the master is the recipient.

Slave Address

The MAX7316 has a 7-bit long slave address (Figure 6).

The eighth bit following the 7-bit slave address is the

R/W bit. The R/W bit is low for a write command, high

for a read command.
