CAT24WC03/05

Doc. No. 1005, Rev. C
FUNCTIONAL DESCRIPTION
The CAT24WC03/05 supports the I
2
C 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. Data transfer is controlled by the Master device
which generates the serial clock and all START and
STOP conditions for bus access. The CAT24WC03/05
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 (24WC03) and 4 devices
(24WC05) may be connected to the bus as determined
by the device address inputs A0, A1, and A2.
PIN DESCRIPTIONS
SCL:
Serial Clock
The CAT24WC03/05 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 CAT24WC03/05 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. When these pins are left floating the default
values are zeros.
A maximum of eight devices can be cascaded when
using the CAT24WC03. All three address pins are used
for CAT24WC03. If only one CAT24WC03 is addressed
on the bus, all three address pins (A0, A1, and A2) can
be left floating or connected to V
