Note 1: Not 100% tested. CB = total capacitance of one bus line in pF.
2: As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region
(minimum 300 ns) of the falling edge of SCL to avoid unintended generation of Start or Stop conditions.
3: The combined TSP and VHYS specifications are due to new Schmitt Trigger inputs, which provide improved
noise spike suppression. This eliminates the need for a TI specification for standard operation.

SDA Serial Data
2.5
Noise Protection
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).
The 24VL014 employs a VCC threshold detector circuit
that disables the internal erase/write logic if the VCC is
below 1.0 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.
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 A0, A1 and A2 inputs are used by the 24VL014 for
multiple device operations. The levels on these inputs
are compared with the corresponding bits in the slave
address. The chip is selected if the compare is true.
Up to eight 24VL014 devices (four for the SOT-23
package) may be connected to the same bus by using
different Chip Select bit combinations. These inputs
must be connected to either VCC or VSS.
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
microcontroller or other programmable device, the chip
address pins must be driven to logic ‘0’ or logic ‘1’
before normal device operation can proceed.
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 and will protect the entire array (00h-7Fh). If
the WP pin is tied to VSS the hardware write protection
is disabled. Write Protection is not available on the
SOT-23 package; for this package, write operations are
always enabled.

FUNCTIONAL DESCRIPTION
The 24VL014 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 24VL014 works as
slave. Both master and slave can operate as
transmitter or receiver, but the master device
determines which mode is activated.

24VL014
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
overwrite 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 24VL014 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 24VL014 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 24VL014 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
For the SOT-23 package, the A2 pin is not connected.
During device addressing, the A2 chip select bit should
be set to logic ‘0’. Only four 24VL014 SOT-23 devices
can be connected to the same bus.
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 24VL014 devices on the same
bus. In this case, software can use A0 of the control
byte as address bit A7, A1 as address bit A8, and A2
as address bit A9. It is not possible to sequentially read
across device boundaries.
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 24VL014
monitors the SDA bus, checking the control byte being
transmitted. Upon receiving a ‘1010’ code and appro-
priate Chip Select bits, the slave device outputs an
Acknowledge signal on the SDA line. Depending on the
state of the R/W bit, the 24VL014 will select a read or
write operation.
For the SOT-23 package, up to four devices can be
added for up to 4 Kbit of address space. In this case,
software can use A0 of the control byte as address bit
A7, and A1 as address bit A8. Bit A2 of the control byte
must always be set to logic ‘0’ for the SOT-23 package.

24VL014
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
internal 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 24VL014.
After receiving another Acknowledge signal from the
24VL014, the master device will transmit the data word
to be written into the addressed memory location. The
24VL014 acknowledges again and the master
generates a Stop condition. This initiates the internal
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.

24VL014
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 24VL014 in the same way
as in a byte write. But instead of generating a Stop
condition, the master transmits up to 15 additional data
bytes to the 24VL014 that are temporarily stored in the
on-chip page buffer and will be written into the memory
once the master has transmitted 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 (00h-7Fh). If the
WP pin is tied to VSS, write operations to all address
locations are allowed. Write protection is not available
on the SOT-23 package; for this package, write
operations are always enabled.

ACKNOWLEDGE POLLING

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.

24VL014
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 24VL014 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 24VL014 discontinues 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 24VL014 contains an address counter that main-
tains 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 24VL014 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
24VL014 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 24VL014 transmits
the first data byte, the master issues an acknowledge
as opposed to a Stop condition in a random read. This
directs the 24VL014 to transmit the next sequentially
addressed 8-bit word (Figure 8-3).
8.2
Random Read
To provide sequential reads, the 24VL014 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. The internal Address
Pointer will automatically roll over from address 7F to
address 00h.
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
24VL014 as part of a write operation.

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
ensure that your application meets with your specifications.
