Description
The CAT24C512 is a EERPOM Serial 512−Kb I2C internally
organized as 65,536 words of 8 bits each.
It features a 128−byte page write buffer and supports the Standard
(100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I2C protocol.
Write operations can be inhibited by taking the WP pin High (this
protects the entire memory).
External address pins make it possible to address up to eight
CAT24C512 devices on the same bus.
On−Chip ECC (Error Correction Code) makes the device suitable
for high reliability applications.

3. Page Mode, VCC = 5 V, 25°C.
4. The device uses ECC (Error Correction Code) logic with 6 ECC bits to correct one bit error in 4 data bytes. Therefore, when a single byte
has to be written, 4 bytes (including the ECC bits) are re-programmed. It is recommended to write by multiple of 4 bytes in order to benefit
from the maximum number of write cycles.

5. These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AEC−Q100
and JEDEC test methods.
6. When not driven, the WP, A0, A1, 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.

CAT24C512
Power-On Reset (POR)
The CAT24C512 incorporates Power−On Reset (POR)
circuitry which protects the internal logic against powering
up in the wrong state.
The device 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 behavior 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
signal 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 CAT24C512 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 CAT24C512 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
Acknowledge Polling
Acknowledge polling can be used to determine if the
CAT24C512 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 CAT24C512 will not acknowledge the Slave address,
as long as internal Write is in progress.
Byte Write
In Byte Write mode the Master sends a START, followed
by Slave address, two byte address and data to be written
(Figure 6). The Slave acknowledges all 4 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.
Hardware Write Protection
With the WP pin held HIGH, the entire memory is
protected against Write operations. If the WP pin is left
floating or is grounded, it has no impact on the operation of
the CAT24C512. 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 CAT24C512 will not acknowledge the data byte
and the Write request will be rejected.
Page Write
The CAT24C512 contains 65,536 bytes of data, arranged
in 512 pages of 128 bytes each. A two byte address word,
following the Slave address, points to the first byte to be
written. The most significant 9 bits (A15 to A7) identify the
page and the last 7 bits identify the byte within the page. Up
to 128 bytes can be written in one Write cycle (Figure 8).
The internal byte address counter is automatically
incremented after each data byte is loaded. If the Master
transmits more than 128 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.
Delivery State
The CAT24C512 is shipped erased, i.e., all bytes are FFh.

CAT24C512
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 two 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 CAT24C512 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 CAT24C512 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 CAT24C512, 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.
