CAT24C512

512 kb I²C CMOS Serial

EEPROM

Description

The CAT24C512 is a 512 kb Serial CMOS EEPROM, internally

organized as 65,536 words of 8 bits each.

http://onsemi.com

It features a 128−byte page write buffer and supports the Standard

2

(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).

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.

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.

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.

CAT24C512

Power-On Reset (POR)

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).

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 V

exceeds the POR trigger level and will power down into

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).

CC

Reset mode when V drops below the POR trigger level.

CC

This bi−directional POR behavior protects the device

against brown−out failure, following a temporary loss of

power.

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.

STOP

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.

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).

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

2

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.

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).

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

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.

CAT24C512

Acknowledge Polling

WRITE OPERATIONS

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 (A to A ) identify the

15

7

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.
