Description  
The Microchip Technology Inc. 24AA014/24LC014 is a  
1 Kbit Serial Electrically Erasable PROM with opera-  
tion down to 1.8V. The device is organized as a single  
block of 128 x 8-bit memory with a 2-wire serial inter-  
face. Low current design permits operation with typical  
standby and active currents of only 1 µA and 1 mA,  
respectively. The device has a page write capability for  
up to 16 bytes of data. Functional address lines allow  
the connection of up to eight 24AA014/24LC014  
devices on the same bus for up to 8 Kbits of contiguous  
EEPROM memory. The device is available in the  
standard 8-pin PDIP, 8-pin SOIC (150 mil), TSSOP and

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 kfor 100 kHz, 2 kfor  
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.  
DS21809B-page 4  
2003 Microchip Technology Inc.  
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.  
4.0  
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 one, a read operation is  
selected. When set to a zero, 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 16K 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.  
DS21809B-page 6

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  
FLOW  
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  
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 incre-  
mented by one at the completion of each operation.  
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:  
DS21809B-page 20  
2003 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 intended through suggestion only  
and may be superseded by updates. It is your responsibility to  
ensure that your application meets with your specifications.  
No representation or warranty is given and no liability is  
assumed by Microchip Technology Incorporated with respect  
to the accuracy or use of such information, or infringement of  
patents or other intellectual property rights arising from such
