128 kb I2C CMOS Serial
EEPROM
Description
The CAT24C128 is a 128 kb Serial CMOS EEPROM, internally
organized as 16,384 words of 8 bits each.
http://onsemi.com
It features a 64−byte page write buffer and supports both the
2
Standard (100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I C
protocol.
Write operations can be inhibited by taking the WP pin High (this
protects the entire memory).
On−Chip ECC (Error Correction Code) makes the device suitable
for high reliability applications.*

4. The new product revision (C) 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.

6. When not driven, the WP pin is 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 V ), the strong pull−down reverts to a weak current source.

CAT24C128
Power−On Reset (POR)
resistors. Master and Slave devices connect to the 2−wire
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 CAT24C128 incorporates Power−On Reset (POR)
circuitry which protects the device against powering up in
the wrong state.
The CAT24C128 will power up into Standby mode after
Data transfer may be initiated only when the bus is not
busy (see A.C. Characteristics).
V
exceeds the POR trigger level and will power down into
CC
Reset mode when V drops below the POR trigger level.
This bi−directional POR feature protects the device against
‘brown−out’ failure following a temporary loss of power.
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). 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. The STOP condition completes all commands.
It consists of a LOW to HIGH transition on SDA while SCL
is HIGH.

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.
Device Addressing
A , A and A : The Address pins accept the device address.

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, A , A and A , select one of 8 possible Slave

devices and must match the state of the external address pins.
The last bit, R/W, specifies whether a Read (1) or Write (0)
operation is to be performed.
Functional Description
The CAT24C128 supports the Inter−Integrated Circuit
2
(I C) Bus data transmission protocol, which defines a device
Acknowledge
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 CAT24C128 acts as a
Slave device. Master and Slave alternate as either
transmitter or receiver. Up to 8 devices may be connected to
After processing the Slave address, the Slave responds
with an acknowledge (ACK) by pulling down the SDA line

acknowledge all address bytes and every data byte presented

CAT24C128
Write Operations
latched and the address count automatically increments to
and then wraps−around at the page boundary. Previously
loaded data can thus be overwritten by new data. What is
eventually written to memory reflects the latest Page Write
Buffer contents. Only data loaded within the most recent
Page Write sequence will be written to memory.
Byte Write
Upon receiving a Slave address with the R/W bit set to ‘0’,
the CAT24C128 will interpret the next two bytes as address
bytes. These bytes are used to initialize the internal address
counter; the 2 most significant bits are ‘don’t care’, the next
8 point to one of 256 available pages and the last 6 point to
a location within a 64 byte page. A byte following the
address bytes will be interpreted as data. The data will be
loaded into the Page Write Buffer and will eventually be
written to memory at the address specified by the 14 active
address bits provided earlier. The CAT24C128 will
acknowledge the Slave address, address bytes and data byte.
The Master then starts the internal Write cycle by issuing a
STOP condition (Figure 6). During the internal Write cycle
Acknowledge Polling
The ready/busy status of the CAT24C128 can be
ascertained by sending Read or Write requests immediately
following the STOP condition that initiated the internal
Write cycle. As long as internal Write is in progress, the
CAT24C128 will not acknowledge the Slave address.
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 CAT24C128. 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 CAT24C128 will not acknowledge the data byte
and the Write request will be rejected.

or Write requests will be ignored (Figure 7).
Page Write
By continuing to load data into the Page Write Buffer after
st
the 1 data byte and before issuing the STOP condition, up
to 64 bytes can be written simultaneously during one
internal Write cycle (Figure 8). If more data bytes are loaded
than locations available to the end of page, then loading will
continue from the beginning of page, i.e. the page address is

Read Operations
Immediate Read
with data, the Master instead follows up with an Immediate
Read sequence, then the CAT24C128 will use the 14 active
address bits to initialize the internal address counter and will
shift out data residing at the corresponding location. If the
Master does not acknowledge the data (NoACK) and then
follows up with a STOP condition (Figure 11), the
CAT24C128 returns to Standby mode.
Upon receiving a Slave address with the R/W bit set to ‘1’,
the CAT24C128 will interpret this as a request for data
residing at the current byte address in memory. The
CAT24C128 will acknowledge the Slave address, will
immediately shift out the data residing at the current address,
and will then wait for the Master to respond. If the Master
does not acknowledge the data (NoACK) and then follows
up with a STOP condition (Figure 10), the CAT24C128
returns to Standby mode.
Sequential Read
If during a Read session the Master acknowledges the 1
st
data byte, then the CAT24C128 will continue transmitting
data residing at subsequent locations until the Master
responds with a NoACK, followed by a STOP (Figure 12).
In contrast to Page Write, during Sequential Read the
address count will automatically increment to and then
wrap−around at end of memory (rather than end of page).
Selective Read
To read data residing at a specific location, the internal
address counter must first be initialized as described under
Byte Write. If rather than following up the two address bytes
