CAT24WC01/02/04/08/16
FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
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
andSTOPconditionsforbusaccess.TheCAT24WC01/
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
isactivated. Amaximumof8devices(CAT24WC01and
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.
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

three address pins are used for these densities. If only
one CAT24WC01 or CAT24WC02 is addressed on the
bus, all three address pins (A0, A1and A2) can be left
floating or connected to VSS.
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.
START Condition
The START Condition precedes all commands to the
device, and is defined as a HIGH to LOW transition of
SDAwhenSCLisHIGH. TheCAT24WC01/02/04/08/16

this condition is met.
A total of four devices can be addressed on a single bus
when using CAT24WC04 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 CAT24WC04 is being addressed on
thebus, theaddresspins(A1andA2)canbeleftfloating
or connected to VSS.

Only two devices can be cascaded when using
CAT24WC08. The only address pin used with this
device is A2. The A0 and A1 address pins are no
connectpinsandcanbetiedtoVSS orleftfloating. Ifonly
one CAT24WC08 is being addressed on the bus, the
addresspin(A2)canbeleftfloatingorconnected toVSS.
DEVICE ADDRESSING
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 CAT24WC01/02/04/08/16 (see Fig. 5).
Thenextthreesignificantbits(A2,A1,A0)arethedevice
addressbitsanddefinewhichdeviceorwhichpartofthe
devicetheMasterisaccessing. UptoeightCAT24WC01/
02, four CAT24WC04, two CAT24WC08, and one
CAT24WC16 may 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.
The CAT24WC16 is a stand alone device. In this case,
all address pins (A0, A1and A2) are no connect pins and
can be tied to VSS or left floating.
WP: Write Protect
If the WP pin is tied to VCC the entire memory array
becomes Write Protected (READ only). When the WP
pin is tied to VSS or left floating normal read/write
operations are allowed to the device.
I2C Bus Protocol
ThefollowingdefinesthefeaturesoftheI2Cbusprotocol:
After the Master sends a START condition and the slave
address byte, the CAT24WC01/02/04/08/16 monitors
the bus and responds with an acknowledge (on the SDA
line) when its address matches the transmitted slave

R/W bit.
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 CAT24WC01/02/04/08/16. After receiving
another acknowledge from the Slave, the Master device
transmits the data byte to be written into the addressed
memory location. The CAT24WC01/02/04/08/16 ac-
knowledge once more and the Master generates the
STOP condition, at which time the device begins its
internalprogrammingcycletononvolatilememory.While
this internal cycle is in progress, the device will not
respond to any request from the Master device.
Acknowledge
Afterasuccessfuldatatransfer, eachreceivingdeviceis
requiredtogenerateanacknowledge.TheAcknowledg-
ing device pulls down the SDA line during the ninth clock
cycle, signaling that it received the 8 bits of data.
The CAT24WC01/02/04/08/16 responds with an ac-
knowledge 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.
When the CAT24WC01/02/04/08/16 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 CAT24WC01/02/04/08/16 will
continue to transmit data. If no acknowledge is sent by
theMaster, thedeviceterminatesdatatransmissionand
waits for a STOP condition.
Page Write
The CAT24WC01/02/04/08/16 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

the Master is allowed to send up to fifteen additional
bytes. After each byte has been transmitted the
CAT24WC01/02/04/08/16 will respond with an
acknowledge, and internally increment the low order
address bits by one. The high order bits remain
unchanged.
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 entire memory array is
protected and becomes read only. The CAT24WC01/
02/04/08/16 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.
If the Master transmits more than sixteen bytes prior to
sendingtheSTOPcondition,theaddresscounter‘wraps
around’, and previously transmitted data will be
overwritten.
Once all sixteen bytes are received and the STOP
condition has been sent by the Master, the internal
programmingcyclebegins.Atthispointallreceiveddata
is written to the CAT24WC01/02/04/08/16 in a single
write cycle.
READ OPERATIONS
The READ operation for the CAT24WC01/02/04/08/16
is initiated in the same manner as the write operation
with the one exception that the R/W bit is set to a one.

operations. After the 24WC01/02/04/08/16 sends initial
8-bit byte requested, the Master will respond with an
acknowledge which tells the device it requires more
data. The CAT24WC01/02/04/08/16 will continue to
output an 8-bit 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.
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 CAT24WC01/02/04/08/16 acknowledge
thewordaddress,theMasterdeviceresendstheSTART
condition and the slave address, this time with the R/W
bit set to one. The CAT24WC01/02/04/08/16 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.
The data being transmitted from the CAT24WC01/02/
04/08/16isoutputtedsequentiallywithdatafromaddress
