CAT24C02C

Doc. No. 25086-00 8/99 S-1
FUNCTIONAL DESCRIPTION
The CAT24C02C 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 CAT24C02C
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.
PIN DESCRIPTIONS
SCL:
Serial Clock
The CAT24C02C 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 CAT24C02C 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.
I
2
C BUS PROTOCOL
The following defines the features of the I
2
C bus proto-
col:
(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.
