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.
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.
This parameter is not tested but ensured by characterization. For endurance estimates in a specific
application, please consult the Total Endurance™ Model, which can be obtained from Microchip’s web site

2.1
SDA Serial Data
This is a bidirectional 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 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
This input is used to synchronize the data transfer from
and to the device.
2.3
A0, A1, A2
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 24C02C 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
This 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 24C02C employs a VCC threshold detector circuit
which disables the internal erase/write logic if the VCC
is below 3.8 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.

FUNCTIONAL DESCRIPTIONS
The 24C02C 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 24C02C 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
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).
4.1
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)
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.
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 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 sixteen
will be stored when doing a write operation. When an
overwrite does occur it will replace data in a first-in firstout fashion.
4.5
Acknowledge
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.
Note:
The 24C02C 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).
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.

DEVICE ADDRESSING
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 24C02C 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 24C02C 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.
The last bit of the control byte defines the operation to
be performed. When set to a ‘1’ a read operation is
selected, and when set to a ‘0’ a write operation is
selected. Following the Start condition, the 24C02C
monitors the SDA bus checking the control byte being
transmitted. Upon receiving a ‘1010’ code and appropriate Chip Select bits, the slave device outputs an
Acknowledge signal on the SDA line. Depending on the
state of the R/W bit, the 24C02C will select a read or
write operation.

The Chip Select bits A2, A1, A0 can be used to expand
the contiguous address space for up to 16K bits by
adding up to eight 24C02C devices on the same bus.
In this case, software can use A0 of the control byte
as address bit A9, A1 as address bit A10, and A2 as
address bit A11. It is not possible to write or read across
device boundaries.

WRITE OPERATIONS
6.1
Byte Write
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 the write
protection is enabled.
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, is 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 24C02C.
After receiving another Acknowledge signal from the
24C02C the master device will transmit the data word
to be written into the addressed memory location. The
24C02C acknowledges again and the master generates a Stop condition. This initiates the internal write
cycle, and during this time the 24C02C will not generate Acknowledge signals (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 the write protection is enabled.
6.2
Note:
Page Write
The write control byte, word address and the first data
byte are transmitted to the 24C02C 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 24C02C 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 four lower
order Address Pointer bits are internally incremented
by one. The higher order four bits of the word address
remains 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.

6.3
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 for the
application software to prevent page write
operations that would attempt to cross a
page boundary.

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. 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, then no ACK will be returned.
If no ACK is returned, then the Start bit and control byte
must be re-sent. 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 7-1 for flow diagram.

READ OPERATION
8.2
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
24C02C 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 24C02C 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 24C02C
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.
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.
8.1
Current Address Read
The 24C02C 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 one,
the 24C02C issues an acknowledge and transmits the
eight bit data word. The master will not acknowledge
the transfer, but does generate a Stop condition and the
24C02C discontinues transmission (Figure 8-1).

Sequential reads are initiated in the same way as a
random read except that after the 24C02C transmits

as opposed to a Stop condition in a random read. This
directs the 24C02C to transmit the next sequentially
addressed 8-bit word (Figure 8-3).

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.
