2.0 PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 2-1.
TABLE 2-1: PIN FUNCTION TABLE
2.1 A0, A1, A2 Chip Address Inputs
The A0, A1 and A2 inputs are used by the 24AA014/
24LC014 for multiple device operation. The levels on
these inputs are compared with the corresponding bits
in the slave address. The chip is selected if the com-
pare is true.
Up to eigh t devi ce s ma y be conn ected to th e sam e bu s
by using different Chip Select bit combinations. These
inputs must be connected to either VCC or VSS.
For the SOT -2 3 devices up to four device s may be con-
nected to the same bus using different Chip Select bit
combinations.
In most applications, the chip address inputs A0, A1
and A2 are hard-wired to logic ‘0’ or logic ‘1’. For
applications in which these pins are controlled by a
microc ontroller or oth er programmabl e device, th e chip
address pins must be driven to logic ‘0’ or logic ‘1’
before normal device operation can proceed.
2.2 Serial Data (SDA)
SDA is a bidirectional pin used to transfer addresses
and data into and out of the de vice . Sinc e it i s an open-
drain terminal, the SDA bus requires a pull-up resistor
to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 4 00 kH z).
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 conditions .
2.3 Serial Clock (SCL)
The SCL in put is u sed to s ynchro niz e th e da ta transf er
from and to the device.
2.4 Write-Protect (WP)
This pin m ust be conne cted to e ither VSS or VCC. If tied
to VSS, write operations are enabled. If tied to VCC,
write operations are inhibited but read operations are
not affected.
3.0 FUNCTIONAL DESCRIPTION
The 24AA014 /24LC014 suppo rts a bidirec tional, 2-wire
bus and data transmission protocol. A device that
sends da ta onto the bus is defin ed as transm itter , while
a device receiving data is defined as a receiver. The
bus h as to be co ntrolled by a master de vice wh ich gen-
erates the Serial Clock (SCL), controls the bus access
and generates the Start and Stop conditions, while the
24AA014/24LC014 works as slave. Both master and
slave can operate as transmitter or receiver, but the
master device determines which mode is activated.

4.0 BUS CHARACTERISTICS
The following bus protocol has been defined:
• Data transfer may be initiated only when the bus
is not busy.
• During data transfer, the data line must remain
stab le when ever th e clock lin e is high . Change s in
the data line while the clock line is high will be
interpreted as a Start or Stop condition.
Accordingly, the following bus conditions have been
defined (Figure 4-1).
4.1 Bus Not Busy (A)
Both data and clock lines remain high.
4.2 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 condition.
4.3 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.
4.4 Data Valid (D)
The state of the data line represents valid data when,
after a Start condition, the data line is stable for the
duratio n of th e high period of the cl ock signal.
The data on the line must be changed during the low
period of the clock signal. There is one bit of data per
clock pulse.
Each dat a transf er is initiated w ith a S tart condition an d
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,
theoret ically, unlimite d, though only the la st sixte en wil l
be stor ed when doing a write opera tion. When a n over-
write doe s occu r, it wi ll re pla ce da ta in a fi rst-in firs t-o ut
fashion.
4.5 Acknowledge
Each receiving device, when addressed, is required to
generate an acknowledge after the reception of each
byte. Th e mast er device mus t ge nera te a n ex tra c lock
pulse, which is associated with this Acknowledge bit.
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 b y not generating an Acknowle dge bit o n 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 (Figure 4-2).

5.0 DEVICE ADDRESSING
A control byte is the first byte received following the
Start condition from the master device (Figure 5-1).
The con tr ol by te cons ists of a fou r-bi t co ntro l code ; for
the 24AA014/24LC014 this is set as ‘1010’ binary for
read and write operations. The next three bits of the
control byte are the Chip Select bits (A2, A1, A0). The
Chip Select bits allow the use of up to eight 24AA014/
24LC014 devices on the same bus and are used to
select which device is accessed. The Chip Select bits
in the control byte must correspond to the logic levels
on the corre sponding A2, A1 an d A0 pins for the devic e
to respond. These bits are in effect the three Most
Significant bits of the word address.
For the SOT-23 package, the A2 address pin is not
available. During device addressing, the A2 Chip
Select bit should be set to ‘0’.
The last bit of the control byte defines the operation to
be performed. When set to a ‘1’, a read operation is
selected. When set to a ‘0’, a write operation is
selected. Following the Start condition, the 24AA014/
24LC014 monitors the SDA bus, checking the control
byte being transmitted. Upon receiving a ‘1010’ code
and appropriate Chip Select bits , the slave device out-
puts an Acknowledge signal on the SDA line. Depend-
ing on the state of the R/W bit , the 2 4AA 014 /24L C0 14
will select a read or write operation.
FIGURE 5-1: CONTROL BYTE FORMAT
5.1 Contiguous Addressing Across
Multi ple Devices
The Chip Select bits A2, A1 and A0 can be used to
expa nd the contiguou s ad dres s sp ac e for up t o 8K bits
by adding up to eight 24AA014/24LC014 devices on
the same bus. In this case, software can use A0 of the
control byte as address bit A8, A1 as address bit A9,
and A2 as address bit A10. It is not possible to
sequentially read across device boundaries.
For the SOT -23 p ackage, up to four 24AA014 /24LC014
devices can be added for up to 4K bits of address
space. In this case, software can use A0 of the control
byte as address bit A8, and A1 as address bit A9. It is
not possible to sequentially read across device bound-
aries.

6.0 WRITE OPERATIONS
6.1 Byte Write
Following the Start signal from the master, the device
code (4 bits), the Chip Select bits (3 bits) and the R/W
bit (which is a logic low) are placed onto the bus by the
master transmitter. The device will acknowledge this
control by te during the ninth clock pulse. The ne xt byte
tran smit ted by the ma ster is the word add res s and wi ll
be written into the Address Pointer of the 24AA014/
24LC014. After receiving another Acknowledge signal
from the 24AA014/24LC014, the master device will
transmit the dat a word to be writt en in to th e ad dres se d
memory location. The 24AA014/24LC014 acknowl-
edges again and the master generates a Stop
condition. This initiates the internal write cycle and the
24AA014/24LC014 will not generate Acknowledge
signals during this time (Figure 6-1). If an attempt is
made to write to the protected portion of the array when
the hardware write protection has been enabled, the
device will acknowledge the command, but no data will
be written. The write cycle time must be observed even
if write protection is enabled.
6.2 Page Write
The write-control byte, word address and the first data
byte are transmitted to the 24AA014/24LC014 in the
same way as in a byte write. But instead of generating
a Stop condition, the master transmits up to 15 addi-
tional data bytes to the 24AA014/24LC014 that are
temporar ily stored in the on-chip page buffer and will be
written into the memory once the master has transmit-
ted a Stop condition. Upon receipt of each word, the
four lower order Address Pointer bits are internally
incremented by one.
The higher order four bits of the word address remain
constant. If the master should transmit more than 16
bytes prior to generating the Stop condition, the
address counter will roll over and the previously
receive d dat a will be overwri tten. As w ith the by te write
operat ion, once the S top co ndition is rece ived, an inter-
nal write cycle will begin (Figure 6-2). If an attempt is
made to write to the protected porti on of the array when
the hardware write protection has been enabled, the
device will ackno wled ge the c omma nd, but n o da ta w ill
be written. The write cycle time must be observed even
if wr ite p rotec tion is enabled.
6.3 Write Protection
The W P pi n m us t be t ie d t o VCC or VSS. If tied to VCC,
the entire array will be write-protected. If the WP pin is
tied to VSS, write op erations to a ll address loc ations are
allowed.
The WP pin is not available on the SOT-23 package.
FIGURE 6-1: BYTE WRITE
Note: Page write opera tions are l imited to wri ting
bytes within a single physical page,
regardless of the number of bytes
actually being written. Physical page
boundaries start at addresses that are
integer multiples of the page buffer size (or
‘page siz e’ ) an d end at ad dres s es 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 w ritten to the next page, as migh t be
expected. It is therefore necessary that the
application software prevent page write
operations that would attempt to cross a
page boundary.

7.0 ACKNOWLEDGE POLLING
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
comma nd has been is sued from the master , the device
initiate s the internally-timed write cycle and ACK polling
can be initiated immediately. This involves the master
sending a Start condition followed by the control byte
for a Write command (R/W = 0). If the device is still
busy wi th t he write cycl e, no ACK wil l be re turned. If no
ACK is returned, the Start bit and control byte must be
re-sent. If the cycle is complete, the device will return
the ACK and the mast er can then pro ceed with the next
Read or Write command. See Figure 7-1 for a flow
diagram of this operation.

8.0 READ OPERATIONS
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 ‘1’. There are three basic types
of read operat ions: current add ress read , rand om rea d
and sequential read.
8.1 Current Address Read
The 24AA014/24LC014 contains an address counter
that maintains the address of the last word accessed,
internally incremented by one. Therefore, if the
previous read access was to address n, the next
current address read operation would access dat a from
address n + 1. Upon receipt of the slave address with
the R/W bi t s et to ‘1’, the 24AA014/24LC014 issues an
acknowledge and transmits the 8-bit data word. The
master will not acknowledge the transfer, but does
generate a Stop condition and the 24AA014/24LC014
discontinues transmission (Figure 8-1).
8.2 Random Read
Random read operations allow the master to access
any memory location in a random manner. To perform
this typ e of re ad ope ratio n, the word add res s mus t firs t
be set. This is done b y sendi ng the word address to the
24AA014/24LC014 as part of a write operation.
Once the word address is s ent, the mas ter generates a
Start condition following the acknowledge. This
terminates the write operation, but not before the
internal Address Pointer is set. Th e mast er then i ssues
the control byte again but with the R/W bit se t to a ‘ 1’.
The 24AA014/24LC014 will then issue an acknowl-
edge an d trans mit s the eight -bit dat a word. The m aster
will not acknowledge the transfer, but does generate a
Stop condition and the 24AA014/24LC014 discontin-
ues tr ans mis sio n (F igure 8-2). Af ter th is comman d, th e
internal address counter will point to the address
location following the one that was just read.
8.3 Sequential Read
Sequential reads are initiated in the same way as a
random read except that after the 24AA014/24LC014
transmits the first data byte, the master issues an
acknowledge as opposed to a Stop condition in a
random read. This directs the 24AA014/24LC014 to
transmit the next sequentially addressed 8-bit word
(Figure 8-3).
To provide sequential reads the 24AA014/24LC014
contains an internal Address Pointer which is
incremented by one at the completion of each opera-
tion. This Address Pointer allows the entire memory
contents to be serially read during one operation. The
internal Address Pointer will automatically roll over
from address 07Fh to address 00 0h.
