CAT34RC02
FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The CAT34RC02 supports the I2C (2-wire) 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 CAT34RC02
operates as a Slave device. Both the Master and Slave
devices can operate as either transmitter or receiver, but
the Master alone assigns those roles. A maximum of 8
devices may be connected to the bus as determined by
the device address inputs A0, A1, and A2.
SCL: Serial Clock
The serial clock input pin is used to clock all data
transfers into or out of the device.
SDA: Serial Data/Address
The bidirectional serial data/address pin is used to
transfer data into and out of the device. This pin is an
open drain output in transmit mode.
A0, A1, A2: Device Address Inputs
These inputs set the device address. When left floating,
the address pins are internally pulled to ground.
WP: Write Protect
This input, when grounded or left floating, allows write
operations to the entire memory. When this pin is tied to
VCC, the entire memory is write protected.

ADDRESS
CAT34RC02
I2C BUS PROTOCOL
Device Addressing
The I2C bus consists of two ‘wires’, SCL and SDA. The
two ‘wires’ are connected to the supply (VCC) via pull-up
resistors. Master and Slave devices connect to the bus
via their respective SCL and SDA pins. The transmitting
device pulls down the SDA line to ‘transmit’ a ‘0’ and
releases it to ‘transmit’ a ‘1’.
The Master initiates a data transfer by creating a START
condition on the bus. The Master then broadcasts an 8bit serial Slave address. The four most significant bits of
the Slave address (the ‘preamble’) are fixed to 1010
(Ah), for normal read/write operations and 0110 (6h) for
Software Write Protect (SWP) operations (Fig. 5). The
next three bits, A2, A1 and A0, select one of eight possible
Slave devices. The last bit, R/W, specifies whether a
Read (1) or Write (0) operation is to be performed.
(1) Data transfer may be initiated only when the bus is
not busy (see A.C. Characteristics).
(2) During a data transfer, the data line must remain
stable whenever the SCL line is high. An SDA
transition while SCL is high will be interpreted as a
START or STOP condition.
Acknowledge
After processing the Slave address, the Slave responds
with an acknowledge (ACK) by pulling down the SDA
line during the 9th clock cycle. The Slave will aslo
acknowledge the 8-bit byte address and every data byte
presented in WRITE mode. In READ mode the Slave
shifts out eight bits of data, and then ‘releases’ the SDA
line durng the 9th clock cycle. If the Master acknowledges
in the 9th clock cycle (by pulling down the SDA line), then
the Slave continues transmitting. When data transfer is
complete, the Master responds with a NoACK (it does
not acknowledge the last data byte) and the Slave stops
transmitting and waits for a STOP condition.
START Condition
The START Condition precedes all commands. It consists
of a HIGH to LOW transition on SDA while SCL is HIGH.
The START condition acts as a ‘wake-up’ call for the
Slave devices. A Slave will not respond to commands
unless the MASTER generates a START condition.
STOP Condition
The STOP condition completes all commands. It consists
of a LOW to HIGH transition on SDA while SCL is HIGH.
The STOP condition starts the internal write cycle, when
following a WRITE command and sends the Slave into
standby mode, when following a READ command.

write is in progress.
WRITE OPERATIONS
Byte Write
WRITE PROTECTION
In Byte Write mode the Master creates a START condition,
and then broadcasts the Slave address, byte address
and data to be written. The Slave acknowledges the
three bytes by pulling down the SDA line during the 9th
clock cycle following each byte. The Master creates a
STOP condition after the last ACK from the Slave, which
then starts the internal write operation (Fig. 6). During
internal write, the Slave will ignore any read/write request
from the Master.
Hardware Write Protection
With the WP pin held HIGH, the entire memory, as well
as the SWP flags are protected against WRITE operations
(Fig. 9). If the WP pin is left floating or is grounded. then
it has no impact on the operation of the CAT34RC02.
Software Write Protection
Page Write
The lower half of memory (first 128 bytes) can be
protected against WRITE operations by setting one of
two Software Write Protection (SWP) flags/switches.
The PSWP (Permanent Software Write Protection) flag
can be set but not cleared by the user. The RSWP
(Reversible Software Write Protection) flag can be set
and cleared by the user. Whereas the PSWP flag can be
set ‘in-system’, the RSWP flag is meant to be used
during testing. RSWP commands require the presence
of a very high voltage (higher than VCC) on address pin
A0 and fixed logic levels for the other two address pins.
The CAT34RC02 contains 256 bytes of data, arranged
in 16 pages of 16 bytes each. The page is selected by the
four most significant bits of the address byte presented
to the device after the Slave address, while the four least
significant bits point to the byte within the page. By
‘loading’ more than one data byte into the device, up to
an entire page can be written in one write cycle (Fig. 7).
The internal byte address counter will increment after
each data byte. If the Master transmits more than 16
data bytes, then earlier bytes will be overwritten by later
bytes in a ‘wrap-around’ fashion within the selected
page. The internal write cycle is started following the
STOP condition created by the Master.
The CAT34RC02 is shipped ‘unprotected’. The state of
the SWP flags can be read by issuing an ‘Immediate
Address Read’ command, with the Slave address
‘preamble’ set to 0110 (6h) instead of the ‘normal’ 1010
(Ah). A SWP READ will return the complemented versions
of the two flags in the last two slots of the resulting data
byte; the other six more significant bits in the data byte
have no meaning to the user (Fig. 11).
Acknowledge Polling
Acknowledge polling can be used to determine if the
CAT34RC02 is busy writing or is ready to accept
commands. Polling is implemented by sending a
‘Selective Read’ command (described under READ
OPERATIONS) to the device. The CAT34RC02 will not

The PSWP flag can be set (forever) by issuing a ‘Byte

‘6h’, followed by a ‘don’t care’ address, followed by ‘don’t

acknowledge the Slave address, dummy byte address
and dummy data (Fig. 10). The PSWP flag will be
permanently set (after the internal write cycle is
completed).

then the CAT34RC02 will not acknowledge the command
itself. In addition, the CAT34RC02 will not acknowledge
a ‘reaffirming’ SWP command, even if the WP pin is
LOW.
Power-On Reset (POR)
The CAT34RC02 incorporates Power-On Reset (POR)
circuitry which protects the device against malfunctioning
while VCC is lower than the recommended operating
voltage.
The SWP commands are shown in Table 1.
Table 1. SWP Commands
The device will power up into a read-only state and will
power-down into a reset state when VCC crosses the
POR level of ~1.3V.

READ OPERATIONS
Immediate Address Read
In standby mode, the CAT34RC02 internal address
counter points to the data byte immediately following the
last byte accessed by a previous operation. If the
‘previous’ byte was the last byte in memory, then the
address counter will point to the first memory byte, etc.
If the CAT34RC02 decodes a Slave address with a ‘1’ in
the R/W bit position (Fig. 8), it will issue an ACK in the 9th
clock cycle, and will then transmit the data byte being
pointed at by the address counter. The Master can then
stop further transmission by issuing a NoACK, followed
by a STOP condition.
The CAT34RC02 will not acknowledge RSWP or PSWP
commands, once the PSWP flag is set. If the PSWP flag
is not set, but the WP pin is HIGH, then the CAT34RC02
will react to RSWP or PSWP commands as follows: if the
command attempts to ‘flip’ one of the two SWP switches,
then the CAT34RC02 will respond the same way the
regular memory would, i.e. the command and address
(in this case dummy) are acknowledged, but the data (in
this case dummy) will not be acknowledged; if the

address counter can be ‘initialized’ by performing a
‘dummy’ WRITE operation (Fig. 12). The START
condition is followed by the Slave address (with the R/W
bit set to ‘0’) and the desired byte address. Instead of
following up with data, the Master then issues a 2nd
START, followed by the ‘Immediate Address Read’
sequence, as described earlier.
Sequential Read
If the Master acknowledges the 1st data byte transmitted
by the CAT34RC02, then the device will continue
transmitting as long as each data byte is acknowledged
by the Master (Fig. 13). If the end of memory is reached
during sequential READ, the address counter will ‘wraparound’ to the beginning of memory, etc. Sequential
READ works with either ‘Immediate Address Read’ or
‘Selective Read’, the only difference being the starting
byte address.
