CAT24C00
SDA: Serial Data/Address
FUNCTIONAL DESCRIPTION
The CAT24C00 bidirectional serial data/address pin is
usedtotransferdataintoandoutofthedevice. TheSDA
pin is an open drain output and can be wire-ORed with
other open drain or open collector outputs.
The CAT24C00 supports the I2C Bus data transmission
protocol.ThisInter-IntegratedCircuitBusprotocoldefines
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 CAT24C00 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.
I2C BUS PROTOCOL
ThefollowingdefinesthefeaturesoftheI2Cbusprotocol:
(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.
PIN DESCRIPTIONS
SCL: Serial Clock
The CAT24C00 serial clock input pin is used to clock all
data transfers into or out of the device. This is an input
pin.

CAT24C00
START Condition
The CAT24C00 responds with an acknowledge after
receivingaSTARTconditionanditsslaveaddress. Ifthe
device has been selected along with a write operation,
it responds with an acknowledge after receiving each 8-
bit byte.
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 CAT24C00 monitors the
SDA and SCL lines and will not respond until this
condition is met.
When the CAT24C00 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 CAT24C00 will continue to transmit data. If no
acknowledgeissentbytheMaster,thedeviceterminates
data transmission and waits for a STOP condition.
STOP Condition

with a STOP condition.
DEVICE ADDRESSING
WRITE OPERATION
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 CAT24C00 (see Fig. 5). The next three
significant bits are "don't care" bits. The last bit of the
slaveaddressspecifieswhetheraReadorWriteoperation
is to be performed. When this bit is set to 1, a Read
operationisselected,andwhensetto0,aWriteoperation
is selected.
Byte Write
In the 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 CAT24C00. After receiving another acknowledge
from the Slave, the Master device transmits the data
byte to be written into the addressed memory location.
The CAT24C00 acknowledges once more and the
MastergeneratestheSTOPcondition, atwhichtimethe
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.
After the Master sends a START condition and the slave
address byte, the CAT24C00 monitors the bus and
responds with an acknowledge (on the SDA line) when
its address matches the transmitted slave address. The
CAT24C00 then performs a Read or Write operation
depending on the state of the R/W bit.
After a write command, the internal address counter
will continue to point to the same address location
that was just written. If a stop bit is transmitted to the
device at any point in the write sequence before the
entire sequence is complete, then the command will
abort and no data will be written. If more than eight

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

Selective Read
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 CAT24C00 acknowledges the word

and the slave address, this time with the R/W bit is set to

begin loading the data buffer again. If more than one
data byte is transmitted to the device and a stop bit
is sent before a full eight bits of data have been
transmitted, then the write command will abort and
no data will be written.

of the typical write cycle time. Once the stop condition
isissuedtoindicatetheendofthehost’swriteoperation,
the CAT24C00 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 CAT24C00 is still busy with
the write operation, no ACK will be returned. If the
CAT24C00 has completed the write operation, an ACK
will be returned and the host can then proceed with the
Sequential Read
The Sequential READ operation can be initiated by
either the immediate Address READ or Selective READ
operations. After the CAT24C00 sends initial 8-bit byte
requested, the Master will respond with an acknowledge
which tells the device it requires more data. The
CAT24C00 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.
next read or write operation.
READ OPERATIONS
TheREADoperationfortheCAT24C00isinitiatedinthe
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.
The data being transmitted from the CAT24C00 is
outputtedsequentiallywithdatafromaddressNfollowed
bydatafromaddressN+1. TheREADoperationaddress
counter increments all of the CAT24C00 address bits so
that the entire memory array can be read during one
operation. Ifmorethan16bytesarereadout, thecounter
will “wrap around” and continue to clock out data bytes.
Immediate Address Read
The device’s address counter contains the address of
the last byte accessed, incremented by one. In other
words, if the last READ access was to address N, the
READ immediately following would access data from
addressN+1.IfN=15,thenthecounterwill'wraparound'
to address 0 and continue to clock out data.
