EEPROM Serial 2-Kb I2C
forDDR2 DIMM SPD
CAT34C02
Description
The CAT34C02 is a EEPROM Serial 2−Kb I2C, internally
organized as 16 pages of 16 bytes each, for a total of 256 bytes of 8 bits
each.
It features a 16−byte page write buffer and supports both the
Standard (100 kHz) as well as Fast (400 kHz) I2C protocol.
Write operations can be inhibited by taking the WP pin High (this
protects the entire memory) or by setting an internal Write Protect flag
via Software command (this protects the lower half of the memory).
In addition to Permanent Software Write Protection, the
CAT34C02 also features JEDEC compatible Reversible Software
Write Protection for DDR2 Serial Presence Detect (SPD)
applications operating over the 1.7 V to 3.6 V supply voltage range.
The CAT34C02 is fully backwards compatible with earlier
DDR1 SPD applications operating over the 1.7 V to 5.5 V supply
voltage range.

4. These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AEC−Q100

5. When not driven, the WP, A0, A1 and A2 pins are pulled down to GND internally. For improved noise immunity, the internal pull−down is relatively
strong; therefore the external driver must be able to supply the pull−down current when attempting to drive the input HIGH. To conserve power,
as the input level exceeds the trip point of the CMOS input buffer (~ 0.5 x VCC), the strong pull−down reverts to a weak current source.

CAT34C02
Power−On Reset (POR)
The CAT34C02 incorporates Power−On Reset (POR)
circuitry which protects the internal logic against powering
up in the wrong state.
The CAT34C02 will power up into Standby mode after
VCC exceeds the POR trigger level and will power down into
Reset mode when VCC drops below the POR trigger level.
This bi−directional POR feature protects the device against
‘brown−out’ failure following a temporary loss of power.
device pulls down the SDA line to ‘transmit’ a ‘0’ and
releases it to ‘transmit’ a ‘1’.
Data transfer may be initiated only when the bus is not
busy (see A.C. Characteristics).
During data transfer, the SDA line must remain stable
while the SCL line is HIGH. An SDA transition while SCL
is HIGH will be interpreted as a START or STOP condition
(Figure 2).
Start
The START condition precedes all commands. It consists
of a HIGH to LOW transition on SDA while SCL is HIGH.
The START acts as a ‘wake−up’ call to all receivers. Absent
a START, a Slave will not respond to commands.
Pin Description
SCL: The Serial Clock input pin accepts the Serial Clock
generated by the Master.
SDA: The Serial Data I/O pin receives input data and
transmits data stored in EEPROM. In transmit mode, this pin
is open drain. Data is acquired on the positive edge, and is
delivered on the negative edge of SCL.
A0, A1 and A2: The Address pins accept the device address.
These pins have on−chip pull−down resistors.
WP: The Write Protect input pin inhibits all write
operations, when pulled HIGH. This pin has an on−chip
pull−down resistor.
Stop
The STOP condition completes all commands. It consists
of a LOW to HIGH transition on SDA while SCL is HIGH.
The STOP starts the internal Write cycle (when following a
Write command) or sends the Slave into standby mode
(when following a Read command).
Device Addressing
The Master initiates data transfer by creating a START
condition on the bus. The Master then broadcasts an 8−bit
serial Slave address. The first 4 bits of the Slave address are
set to 1010, for normal Read/Write operations (Figure 3).
The next 3 bits, A2, A1 and A0, select one of 8 possible Slave
devices. The last bit, R/W, specifies whether a Read (1) or
Write (0) operation is to be performed.
Functional Description
The CAT34C02 supports the Inter−Integrated Circuit
(I2C) Bus data transmission protocol, which defines a device
that sends data to the bus as a transmitter and a device
receiving data as a receiver. Data flow is controlled by a
Master device, which generates the serial clock and all
START and STOP conditions. The CAT34C02 acts as a
Slave device. Master and Slave alternate as either
transmitter or receiver. Up to 8 devices may be connected to
the bus as determined by the device address inputs A0, A1,
and A2.
Acknowledge
After processing the Slave address, the Slave responds
with an acknowledge (ACK) by pulling down the SDA line
during the 9th clock cycle (Figure 4). The Slave will also
acknowledge the byte address and every data byte presented
in Write mode. In Read mode the Slave shifts out a data byte,
and then releases the SDA line during the 9th clock cycle. If
the Master acknowledges the data, then the Slave continues
transmitting. The Master terminates the session by not
acknowledging the last data byte (NoACK) and by sending
a STOP to the Slave. Bus timing is illustrated in Figure 5.
I2C Bus Protocol
The I2C bus consists of two ‘wires’, SCL and SDA. The
two wires are connected to the VCC supply via pull−up
resistors. Master and Slave devices connect to the 2−wire
bus via their respective SCL and SDA pins. The transmitting

Write Operations
The internal byte address counter is automatically
incremented after each data byte is loaded. 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 starts
immediately following the STOP.
Byte Write
In Byte Write mode the Master sends a START, followed
by Slave address, byte address and data to be written
(Figure 6). The Slave acknowledges all 3 bytes, and the
Master then follows up with a STOP, which in turn starts the
internal Write operation (Figure 7). During internal Write,
the Slave will not acknowledge any Read or Write request
from the Master.
Acknowledge Polling
Acknowledge polling can be used to determine if the
CAT34C02 is busy writing or is ready to accept commands.
Polling is implemented by interrogating the device with a
‘Selective Read’ command (see READ OPERATIONS).
The CAT34C02 will not acknowledge the Slave address,
as long as internal Write is in progress.
Page Write
The CAT34C02 contains 256 bytes of data, arranged in 16
pages of 16 bytes each. A page is selected by the 4 most
significant bits of the address byte following the Slave
address, while the 4 least significant bits point to the byte
within the page. Up to 16 bytes can be written in one Write
cycle (Figure 8).
Delivery State
The CAT34C02 is shipped ‘unprotected’, i.e. neither SWP
flag is set. The entire 2 kb memory is erased, i.e. all bytes are
FFh.

CAT34C02
Read Operations
The address counter can be initialized by performing a
‘dummy’ Write operation (Figure 11). Here the START 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.
Immediate Address Read
In standby mode, the CAT34C02 internal address counter
points to the data byte immediately following the last byte
accessed by a previous operation. If that ‘previous’ byte was
the last byte in memory, then the address counter will point
to the 1st memory byte, etc.
When, following a START, the CAT34C02 is presented
with a Slave address containing a ‘1’ in the R/W bit position
(Figure 10), it will acknowledge (ACK) in the 9th clock cycle,
and will then transmit data being pointed at by the internal
address counter. The Master can stop further transmission by
issuing a NoACK, followed by a STOP condition.
Sequential Read
If the Master acknowledges the 1st data byte transmitted
by the CAT34C02, then the device will continue
transmitting as long as each data byte is acknowledged by
the Master (Figure 12). If the end of memory is reached
during sequential Read, then the address counter will
‘wrap−around’ 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.
Selective Read
The Read operation can also be started at an address
different from the one stored in the internal address counter.

CAT34C02
Software Write Protection
The lower half of memory (first 128 bytes) can be
protected against Write requests by setting one of two
Software Write Protection (SWP) flags.
The Permanent Software Write Protection (PSWP) flag
can be set or read while all address pins are at regular CMOS
levels (GND or VCC), whereas the very high voltage VHV
must be present on address pin A0 to set, clear or read the
Reversible Software Write Protection (RSWP) flag. The
D.C. OPERATING CONDITIONS for RSWP operations
are shown in Table 8.
The SWP commands are listed in Table 9. All commands
are preceded by a START and terminated with a STOP,
following the ACK or NoACK from the CAT34C02. All
SWP related Slave addresses use the pre−amble: 0110 (6h),
instead of the regular 1010 (Ah) used for memory access.
For PSWP commands, the three address pins can be at any
logic level, whereas for RSWP commands the address pins
must be at pre−assigned logic levels. VHV is interpreted as
logic ‘1’. The VHV condition must be established on pin A0
before the START and maintained just beyond the STOP.
Otherwise an RSWP request could be interpreted by the
CAT34C02 as a PSWP request.
The SWP Slave addresses follow the standard I2C
convention, i.e. to read the state of the SWP flag, the LSB of
the Slave address must be ‘1’, and to set or clear a flag, it
must be ‘0’. For Write commands a dummy byte address and
dummy data byte must be provided (Figure 14). In contrast
to a regular memory Read, a SWP Read does not return Data.
Instead the CAT34C02 will respond with NoACK if the flag
is set and with ACK if the flag is not set. Therefore, the
Master can immediately follow up with a STOP, as there is
no meaningful data following the ACK interval (Figure 15).
Hardware Write Protection
With the WP pin held HIGH, the entire memory, as well
as the SWP flags are protected against Write operations, see
Memory Protection Map below. If the WP pin is left floating
or is grounded, it has no impact on the operation of the
CAT34C02.
The state of the WP pin is strobed on the last falling edge
of SCL immediately preceding the first data byte (Figure 9).
If the WP pin is HIGH during the strobe interval, the
CAT34C02 will not acknowledge the data byte and the Write
request will be rejected.

11. To prevent damaging the CAT34C02 while applying VHV, it is strongly recommended to limit the power delivered to pin A0, by inserting a series
resistor (> 1.5 kW) between the supply and the input pin. The resistance is only limited by the combination of VHV and maximum IHVD. While
the resistor can be omitted if VHV is clamped well below 10 V, it nevertheless provides simple protection against EOS events.
As an example: VCC = 1.7 V, VHV = 8 V, 1.5 kW < RS < 15 kW.
