FUNCTIONAL DESCRIPTION
The 24AA01/02 supports a bi directional 2-wire bus
and data transmission protocol. A device that sends
data onto the bus is defined as transmitter, and a
device receiving data as receiver. The bus has to be
controlled by a master device which generates the
serial clock (SCL), controls the bus access, and gener-
ates the START and STOP conditions, while the
24AA01/02 works as slave. Both, master and slave can
operate as transmitter or receiver but the master device
determines which mode is activated.
The state of the data line represents valid data when,
after a START condition, the data line is stable for the
duration of the HIGH period of the clock signal.
The data on the line must be changed during the LOW
period of the clock signal. There is one clock pulse per
bit of data.
Each data transfer is initiated with a START condition
and terminated with a STOP condition. The number of
the data bytes transferred between the START and
STOP conditions is determined by the master device
and is theoretically unlimited, although only the last 16
will be stored when doing a write operation. When an
overwrite does occur it will replace data in a first in first
out fashion.
3.0
BUS CHARACTERISTICS
The following bus protocol has been defined:
• Data transfer may be initiated only when the bus
is not busy.
3.5
Acknowledge
• During data transfer, the data line must remain
stable whenever the clock line is HIGH. Changes
in the data line while the clock line is HIGH will be
interpreted as a START or STOP condition.
Each receiving device, when addressed, is obliged to
generate an acknowledge after the reception of each
byte. The master device must generate an extra clock
pulse which is associated with this acknowledge bit.
Accordingly, the following bus conditions have been
defined (Figure 3-1).
Note: The 24AA01/02 does not generate any
acknowledge bits if an internal program-
ming cycle is in progress.
3.1
Bus not Busy (A)
Both data and clock lines remain HIGH.
The device that acknowledges, has to pull down the
SDA line during the acknowledge clock pulse in such a
way that the SDA line is stable LOW during the HIGH
period of the acknowledge related clock pulse. Of
course, setup and hold times must be taken into
account. A master must signal an end of data to the
slave by not generating an acknowledge bit on the last
byte that has been clocked out of the slave. In this
case, the slave must leave the data line HIGH to enable
the master to generate the STOP condition.
3.2
Start Data Transfer (B)
A HIGH to LOW transition of the SDA line while the
clock (SCL) is HIGH determines a START condition.
All commands must be preceded by a START condi-
tion.
3.3
Stop Data Transfer (C)
A LOW to HIGH transition of the SDA line while the
clock (SCL) is HIGH determines a STOP condition. All
operations must be ended with a STOP condition.

WRITE OPERATION
The 24AA01/02 are software-compatible with older
devices such as 24C01A, 24C02A, 24LC01, and
24LC02. A single 24AA02 can be used in place of two
24LC01's, for example, without any modifications to
software. The “chip select” portion of the control byte
becomes a don't care.
4.1
Byte Write
Following the start signal from the master, the device
code (4 bits), the don't care bits (3 bits), and the R/W
bit which is a logic low is placed onto the bus by the
master transmitter. This indicates to the addressed
slave receiver that a byte with a word address will follow
after it has generated an acknowledge bit during the
ninth clock cycle.Therefore the next byte transmitted by
the master is the word address and will be written into
the address pointer of the 24AA01/02. After receiving
another acknowledge signal from the 24AA01/02 the
master device will transmit the data word to be written
into the addressed memory location. The 24AA01/02
acknowledges again and the master generates a stop
condition.This initiates the internal write cycle, and dur-
ing this time the 24AA01/02 will not generate acknowl-
edge signals (Figure 4-1).
After generating a START condition, the bus master
transmits the slave address consisting of a 4-bit device
code (1010) for the 24AA01/02, followed by three don't
care bits.
The eighth bit of slave address determines if the master
device wants to read or write to the 24AA01/02
(Figure 3-2).
The 24AA01/02 monitors the bus for its corresponding
slave address all the time. It generates an acknowledge
bit if the slave address was true and it is not in a pro-
gramming mode.
4.2
Page Write
Control
Code
Operation
Chip Select
R/W
The write control byte, word address and the first data
byte are transmitted to the 24AA01/02 in the same way
as in a byte write. But instead of generating a stop con-
dition the master transmits up to eight data bytes to the
24AA01/02 which are temporarily stored in the on-chip
page buffer and will be written into the memory after the
master has transmitted a stop condition. After the
receipt of each word, the three lower order address
pointer bits are internally incremented by one. The
higher order five bits of the word address remains con-
stant. If the master should transmit more than eight
words prior to generating the stop condition, the
address counter will roll over and the previously
received data will be overwritten. As with the byte write
operation, once the stop condition is received an inter-
nal write cycle will begin (Figure 7-1).

Note: Page write operations are limited to writing
bytes within a single physical page, regard-
less of the number of bytes actually being
written. Physical page boundaries start at
addresses that are integer multiples of the
page buffer size (or Ôpage sizeÕ) and end at
addresses that are integer multiples of
[page size - 1]. If a page write command
attempts to write across a physical page
boundary, the result is that the data wraps
around to the beginning of the current page
(overwriting data previously stored there),
instead of being written to the next page as
might be expected. It is therefore neces-
sary for the application software to prevent
page write operations that would attempt to
cross a page boundary.

ACKNOWLEDGE POLLING
7.0
READ OPERATION
Since the device will not acknowledge during a write
cycle, this can be used to determine when the cycle is
complete (this feature can be used to maximize bus
throughput). Once the stop condition for a write com-
mand has been issued from the master, the device ini-
tiates the internally timed write cycle. ACK polling can
be initiated immediately.This involves the master send-
ing a start condition followed by the control byte for a
write command (R/W = 0). If the device is still busy with
the write cycle, then no ACK will be returned. If the
cycle is complete, then the device will return the ACK
and the master can then proceed with the next read or
write command. See Figure 5-1 for flow diagram.
Read operations are initiated in the same way as write
operations with the exception that the R/W bit of the
slave address is set to one. There are three basic types
of read operations: current address read, random
read, and sequential read.
7.1
Current Address Read
The 24AA01/02 contains an address counter that
maintains the address of the last word accessed, inter-
nally incremented by one. Therefore, if the previous
access (either a read or write operation) was to
address n, the next current address read operation
would access data from address n + 1. Upon receipt of
the slave address with R/W bit set to one, the 24AA01/
02 issues an acknowledge and transmits the eight bit
data word. The master will not acknowledge the trans-
fer but does generate a stop condition and the 24AA01/
02 discontinues transmission (Figure 7-1).
FIGURE 5-1: ACKNOWLEDGE POLLING
FLOW
Send
Write Command
7.2
Random Read
Random read operations allow the master to access
any memory location in a random manner. To perform
this type of read operation, first the word address must
be set.This is done by sending the word address to the
24AA01/02 as part of a write operation. After the word
address is sent, the master generates a start condition
following the acknowledge. This terminates the write
operation, but not before the internal address pointer is
set. Then the master issues the control byte again but
with the R/W bit set to a one. The 24AA01/02 will then
issue an acknowledge and transmits the eight bit data
word. The master will not acknowledge the transfer but
does generate a stop condition and the 24AA01/02 dis-
continues transmission (Figure 7-2).

7.3
Sequential Read
(ACK = 0)?
Sequential reads are initiated in the same way as a ran-
dom read except that after the 24AA01/02 transmits the
first data byte, the master issues an acknowledge as
opposed to a stop condition in a random read. This
directs the 24AA01/02 to transmit the next sequentially
addressed 8-bit word (Figure 7-3).
Yes
Next
Operation
To provide sequential reads the 24AA01/02 contains an
internal address pointer which is incremented by one at
the completion of each operation. This address pointer
allows the entire memory contents to be serially read
during one operation.
6.0
WRITE PROTECTION
The 24AA01/02 can be used as a serial ROM when the
WP pin is connected to VCC. Programming will be inhib-
ited and the entire memory will be write-protected.
7.4
Noise Protection
The 24AA01/02 employs a VCC threshold detector cir-
cuit which disables the internal erase/write logic if the
VCC is below 1.5 volts at nominal conditions.
The SCL and SDA inputs have Schmitt trigger and filter
circuits which suppress noise spikes to assure proper
device operation even on a noisy bus.

PIN DESCRIPTIONS
This pin must be connected to either VSS or VCC.
8.1
SDA Serial Address/Data Input/Output
If tied to VSS, normal memory operation is enabled
(read/write the entire memory).
This is a bi-directional pin used to transfer addresses
and data into and data out of the device. It is an open
drain terminal, therefore the SDA bus requires a pullup
resistor to VCC (typical 10KΩ for 100 kHz, 2K for 400
kHz).
If tied to VCC, WRITE operations are inhibited. The
entire memory will be write-protected. Read opera-
tions are not affected.
This feature allows the user to use the 24AA01/02 as a
serial ROM when WP is enabled (tied to VCC).
For normal data transfer SDA is allowed to change only
during SCL low. Changes during SCL high are
reserved for indicating the START and STOP condi-
tions.
8.4
A0, A1, A2
These pins are not used by the 24AA01/02. They may
be left floating or tied to either VSS or VCC.
8.2
SCL Serial Clock
This input is used to synchronize the data transfer from
and to the device.
