CAT9552

FUNCTIONAL DESCRIPTION

The CAT9552 is a 16-channel I/O bus expander that

provides a pair of programmable LED blinkers,

controlled through an I²C compatible serial interface.

SDA when SCL is HIGH. The CAT9552 monitors the

SDA and SCL lines and will not respond until this

condition is met.

CAT9552 supports the I²C Bus data transmission

protocol. This Inter-Integrated Circuit Bus protocol

defines any device that sends data to the bus to be a

transmitter and any device receiving data to be a

receiver. The transfer is controlled by the Master

device which generates the serial clock and all

START and STOP conditions for bus access. The

CAT9552 operates as a Slave device. Both the

Master device and Slave device can operate as either

transmitter or receiver, but the Master device controls

which mode is activated.

A LOW to HIGH transition of SDA when SCL is HIGH

determines the STOP condition. All operations must

end with a STOP condition.

Device Addressing

After the bus Master sends a START condition, a

slave address byte is required to enable the CAT9552

for a read or write operation. The four most significant

bits of the slave address are fixed as binary 1100

(Figure 3). The CAT9552 uses the next three bits as

address bits.

I²C Bus Protocol

The features of the I²C bus protocol are defined as

follows:

The address bits A2, A1 and A0 are used to select

which device is accessed from maximum eight

devices on the same bus. These bits must compare to

their hardwired input pins. The 8th bit following the 7-

bit slave address is the R/W bit that specifies whether

a read or write operation is to be performed. When

this bit is set to “1”, a read operation is initiated, and

when set to “0”, a write operation is selected.

(1) Data transfer may be initiated only when the bus

is not busy.

(2) During a data transfer, the data line must remain

stable whenever the clock line is high. Any

changes in the data line while the clock line is

high will be interpreted as a START or STOP

condition (Figure 2).

Following the START condition and the slave address

byte, the CAT9552 monitors the bus and responds

with an acknowledge (on the SDA line) when its

address matches the transmitted slave address. The

CAT9552 then performs a read or a write operation

depending on the state of the R/W bit.

START and STOP Conditions

The START Condition precedes all commands to the

device, and is defined as a HIGH to LOW transition of

SDA
