FUNCTIONAL DESCRIPTION
The 24AA014/24LC014 supports a bidirectional, 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 that generates 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.
This is a bidirectional pin used to transfer addresses
and data into and out of the device. It is an open drain
terminal. Therefore, the SDA bus requires a pull-up
resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for
400 kHz).
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.
2.2
SCL Serial Clock
The SCL input is used to synchronize the data transfer
to and from the device.
2.3
A0, A1, A2
The levels on the inputs A0, A1 and A2 are compared
with the corresponding bits in the slave address. The
chip is selected if the compare is true.
Up to eight 24AA014/24LC014 devices may be
connected to the same bus by using different Chip
Select bit combinations. These inputs must be
connected to either VCC or VSS.
2.4
WP
WP is the hardware write-protect pin. It must be tied to
VCC or VSS. If tied to VCC, the hardware write protection
is enabled. If the WP pin is tied to VSS the hardware
write protection is disabled.
2.5
Noise Protection
The 24AA014/24LC014 employs a VCC threshold
detector circuit that 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 that suppress noise spikes to assure
proper device operation even on a noisy bus.
DS21809C-page 4

24AA014/24LC014
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.

BUS CHARACTERISTICS
The following bus protocol has been defined:
• Data transfer may be initiated only when the bus
is not busy.
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, though only the last sixteen will
be stored when doing a write operation. When an over-
write does occur, it will replace data in a first-in first-out
fashion.
• 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.
Accordingly, the following bus conditions have been
defined (Figure 4-1).
4.5
Acknowledge
4.1
Bus Not Busy (A)
Each receiving device, when addressed, is required 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.
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.
Note:
The 24AA014/24LC014 does not generate
any Acknowledge bits if an internal
programming cycle is in progress.
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 (Figure 4-2).
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
duration of the high period of the clock signal.

CONTROL BYTE FORMAT
5.0
DEVICE ADDRESSING
Read/Write Bit
A control byte is the first byte received following the
Start condition from the master device (Figure 5-1).
The control byte consists of a four-bit control 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 corresponding A2, A1 and A0 pins for the device
to respond. These bits are in effect the three Most
Significant bits of the word address.

Contiguous Addressing Across
Multiple Devices
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 24AA014/24LC014
will select a read or write operation.
The Chip Select bits A2, A1 and A0 can be used to
expand the contiguous address space for up to 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.

24AA014/24LC014
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
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 6-2). 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.
6.0
6.1
WRITE OPERATIONS
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 byte during the ninth clock pulse. The next byte
transmitted by the master is the word address and will
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 data word to be written into the addressed
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.
Note:
Page write operations are limited to writing
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 size’) 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 necessary that the
application software prevent page write
operations that would attempt to cross a
page boundary.
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
temporarily 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.
6.3
Write Protection
The WP pin must be tied to VCC or VSS. If tied to VCC,
the entire array will be write-protected. If the WP pin is
tied to VSS, write operations to all address locations are
allowed.

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
command has been issued from the master, the device
initiates 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 with the write cycle, no ACK will be returned. 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 master can then proceed with the next
Read or Write command. See Figure 7-1 for a flow
diagram of this operation.

24AA014/24LC014
Once 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. The master then issues
the control byte again but with the R/W bit set to a ‘1’.
The 24AA014/24LC014 will then issue an acknowl-
edge and transmits the eight-bit data word. The master
will not acknowledge the transfer, but does generate a
Stop condition and the 24AA014/24LC014 discontin-
ues transmission (Figure 8-2). After this command, the
internal address counter will point to the address
location following the one that was just read.
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 operations: current address read, random read
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 data from
address n + 1. Upon receipt of the slave address with
the R/W bit set 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).
8.3
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).
8.2
Random Read
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 0FFh to address 000h.
Random read operations allow the master to access
any memory location in a random manner. To perform
this type of read operation, the word address must first
be set. This is done by sending the word address to the
24AA014/24LC014 as part of a write operation.

NOTES:
DS21809C-page 22
© 2005 Microchip Technology Inc.
Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
