Doc. No. 1025, Rev. E
FUNCTIONAL DESCRIPTION
The CAT34AC02 supports the SMBus data transmission
protocol. This serial protocol defines any device that
sends data to the bus to be a transmitter and any device
receiving data to be a receiver. Data transfer is controlled
by the Master device which generates the serial clock
and all START and STOP conditions for bus access. The
CAT34AC02 operates as a Slave device. Both the
Master and Slave devices can operate as either
transmitter or receiver, but the Master device controls
which mode is activated. A maximum of 8 devices may
be connected to the bus as determined by the device
address inputs A0, A1, and A2.
PIN DESCRIPTIONS
SCL:
Serial Clock
The CAT34AC02 serial clock input pin is used to clock
all data transfers into or out of the device. This is an input
pin.
SDA:
Serial Data/Address
The CAT34AC02 bidirectional serial data/address pin is
used to transfer data into and out of the device. The SDA
pin is an open drain output and can be wire-ORed with
other open drain or open collector outputs.
A0, A1, A2:
Device Address Inputs
These inputs set device address when cascading multiple
devices. A maximum of eight devices can be cascaded
when using the device.
WP:
Write Protect
This input, when tied to GND, allows write operations to
the entire memory. For CAT34AC02 when this pin is tied
to V
CC
, the entire array of memory is write protected.
When left floating, memory is unprotected.
