CAT24WC03/05
FUNCTIONAL DESCRIPTION
clock all data transfers into or out of the device. This is
an input pin.
The CAT24WC03/05 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 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.
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.
SCL: Serial Clock

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 VSS.

CAT24WC03/05
A total of four devices can be addressed on a single bus
when using the CAT24WC05 device. Only A1 and A2
address pins are used with this device. The A0 address
pin is a no connect pin and can be tied to VSS or left
floating. If only one CAT24WC05 is being addressed on
the bus, the address pins (A1 and A2) can be left floating
or connected to VSS.
STOP Condition
WP: Write Protect
If the WP pin is tied to VCC the upper half of memory array
becomes Write Protected (READ only)(locations 80H to
FFH for the CAT24WC03 and locations 100H to 1FFH
for the CAT24WC05). When the WP pin is tied to VSS or
left floating normal read/write operations are allowed to
the device.
The bus Master begins a transmission by sending a
START condition. The Master then sends the address
of the particular slave device it is requesting. The four
most significant bits of the 8-bit slave address are fixed
as 1010 for the CAT24WC03/05 (see Fig. 5). The next
three significant bits (A2, A1, A0) are the device address
bits and define which device or which part of the device
the Master is accessing. Up to eight CAT24WC03 and
four CAT24WC05 can be individually addressed by the
system. The last bit of the slave address specifies
whether a Read or Write operation is to be performed.
When this bit is set to 1, a Read operation is selected,
and when set to 0, a Write operation is selected.
A LOW to HIGH transition of SDA when SCL is HIGH
determines the STOP condition. All operations must end
with a STOP condition.
DEVICE ADDRESSING
I2C BUS PROTOCOL
The following defines the features of the I2C bus protocol:
d
e
(1) Data transfer may be initiated only when the bus is
not busy.
After the Master sends a START condition and the slave
address byte, the CAT24WC03/05 monitors the bus and
responds with an acknowledge (on the SDA line) when
its address matches the transmitted slave address. The
CAT24WC03/05 then performs a Read or Write operation
depending on the state of the R/W bit.
(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.
it
n
o
START Condition
u
n
Acknowledge
The START Condition precedes all commands to the
device, and is defined as a HIGH to LOW transition of
SDA when SCL is HIGH. The CAT24WC03/05 monitor
the SDA and SCL lines and will not respond until this
condition is met.
c
s
a
P
s
t
r
After a successful data transfer, each receiving device is
required to generate an acknowledge. The
Acknowledging device pulls down the SDA line during
the ninth clock cycle, signaling that it received the 8 bits
of data.

CAT24WC03/05
The CAT24WC03/05 responds with an acknowledge
after receiving a START condition and its slave address.
If the device has been selected along with a write
operation, it responds with an acknowledge after receiving
each 8-bit byte.
The CAT24WC03/05 writes up to 16 bytes of data in a
single write cycle, using the Page Write operation. The
Page Write operation is initiated in the same manner as
the Byte Write operation; however, instead of terminating
after the initial word is transmitted, the Master is allowed
to send up to 15 additional bytes. After each byte has
been transmitted, the CAT24WC03/05 will respond with
an acknowledge and internally increment the low order
address bits by one. The high order bits remain
unchanged.
When the CAT24WC03/05 is in a READ mode it transmits
8 bits of data, releases the SDA line, and monitors the
line for an acknowledge. Once it receives this
acknowledge, the CAT24WC03/05 will continue to
transmit data. If no acknowledge is sent by the Master,
the device terminates data transmission and waits for a
STOP condition.
WRITE OPERATIONS
In the Byte Write mode, the Master device sends the
START condition and the slave address information
(with the R/W bit set to zero) to the Slave device. After
the Slave generates an acknowledge, the Master sends
the byte address that is to be written into the address
pointer of the CAT24WC03/05. After receiving another
acknowledge from the Slave, the Master device transmits
the data byte to be written into the addressed memory
location. The CAT24WC03/05 acknowledge once more
and the Master generates the STOP condition, at which
time the device begins its internal programming cycle to
nonvolatile memory. While this internal cycle is in
progress, the device will not respond to any request from
the Master device.

Once all 16 bytes are received and the STOP condition

If the Master transmits more than 16 bytes prior to

Acknowledge Polling
The disabling of the inputs can be used to take advantage
of the typical write cycle time. Once the stop condition
is issued to indicate the end of the host’s write operation,
the CAT24WC03/05 initiates the internal write cycle.
ACK polling can be initiated immediately. This involves
issuing the start condition followed by the slave address
for a write operation. If the CAT24WC03/05 is still busy
with the write operation, no ACK will be returned. If the
CAT24WC03/05 has completed the write operation, an
ACK will be returned and the host can then proceed with
the next read or write operation.

CAT24WC03/05
In other words, if the last READ or WRITE access was
to address N, the READ immediately following would
access data from address N+1. If N=E (where E = 255
for the CAT24WC03 and 511 for the CAT24WC05), then
the counter will ‘wrap around’ to address 0 and continue
to clock out data. After the CAT24WC03/05 receives its
slave address information (with the R/W bit set to one),
it issues an acknowledge, then transmits the 8-bit byte
requested. The master device does not send an
acknowledge but will generate a STOP condition.
WRITE PROTECTION
The Write Protection feature allows the user to protect
against inadvertent programming of the memory array.
If the WP pin is tied to VCC, the upper half (locations 80H
to FFH for CAT24WC03 and locations 100H to 1FFH for
CAT24WC05) of the memory array is protected and
becomes read only. The CAT24WC03/05 will accept
both slave and byte addresses, but the memory location
accessed is protected from programming by the device’s
failure to send an acknowledge after the first byte of data
is received.
Selective Read
READ OPERATIONS
The READ operation for the CAT24WC03/05 is initiated
in the same manner as the write operation with the one
exception that the R/W bit is set to a one. Three different
READ operations are possible: Immediate Address
READ, Selective READ and Sequential READ.
Immediate Address Read
The CAT24WC03/05 address counter contains the
address of the last byte accessed incremented by one.

Selective READ operations allow the Master device to
select at random any memory location for a READ
operation. The Master device first performs a ‘dummy’
write operation by sending the START condition, slave
address and byte address of the location it wishes to
read. After the CAT24WC03/05 acknowledge the word
address, the Master device resends the START condition
and the slave address, this time with the R/W bit set to
one. The CAT24WC03/05 then responds with its
acknowledge and sends the 8-bit byte requested. The
master device does not send an acknowledge but will
generate a STOP condition.

CAT24WC03/05
Sequential Read
The data being transmitted from the CAT24WC03/05 is
outputted sequentially with data from address N followed
by data from address N+1. The READ operation address
counter increments all of the CAT24WC03/05 address
bits so that the entire memory array can be read during
one operation. If more than the E (where E = 255 for the
CAT24WC03 and 511 for the CAT24WC05) bytes are
read out, the counter will “wrap around” and continue to
clock out data bytes.
The Sequential READ operation can be initiated by
either the Immediate Address READ or Selective READ
operations. After the CAT24WC03/05 sends the initial 8bit byte requested, the Master will respond with an
acknowledge which tells the device it requires more
data. The CAT24WC03/05 will continue to output an 8bit byte for each acknowledge sent by the Master. The
operation is terminated when the Master fails to respond
with an acknowledge, thus sending the STOP condition.
