FUNCTIONAL DESCRIPTION
The CAT24WC01/02/04/08/16 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. Data transfer is controlled by the Master
device which generates the serial clock and all START
and STOP conditions for bus access. The CAT24WC01/
02/04/08/16 operates as a Slave device. Both the Mas-
ter and Slave devices can operate as either transmitter
or receiver, but the Master device controls which mode
is activated. A maximum of 8 devices (CAT24WC01 and
CAT24WC02), 4 devices (CAT24WC04), 2 devices
(CAT24WC08) and 1 device (CAT24WC16) may be
connected to the bus as determined by the device
address inputs A0, A1, and A2.
PIN DESCRIPTIONS
SCL:
Serial Clock
The CAT24WC01/02/04/08/16 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 CAT24WC01/02/04/08/16 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 mul-
tiple devices.
When these pins are left floating the
default values are zeros.
A maximum of eight devices can be cascaded when
