FUNCTIONAL DESCRIPTION
The CAT34WC02 supports the I
2
C Bus data transmis-
sion 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 re-
ceiver. Data transfer is controlled by the Master device
which generates the serial clock and all START and
STOP conditions for bus access. The CAT34WC02
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 CAT34WC02 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 CAT34WC02 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.
These inputs set device address when cascading mul-
tiple 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 CAT34WC02 when this pin is
tied to V
CC
, the entire array of memory is write protected.
When left floating, memory is unprotected.
