2.0 PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 2-1.
TABLE 2-1: PIN FUNCTION TABLE
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 pull-up
resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for
400 kHz).
For norma l data trans fer SDA is all owed 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 i nput is u sed t o sy nchron ize the d ata trans fer fro m
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 combina-
tions. T hese i nput s mu st be c onnec ted to e ither VCC or
VSS.
2.4 WP
This is the hardware write-p rotect pin. It must be tie d to
VCC or VSS. If tied to Vcc, the ha rdware write protectio n
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.
3.0 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
receivi ng data as receiver . The bus has t o be controlle d
by a master device which generates the Serial Clock
(SCL), controls the bus access, and generates the S tart
and S t op conditi ons, while the 24C02C works as slave.
Both master and slave can operate as transmitter or
receive r but th e mas ter devic e det ermine s whic h mod e
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 (Fig ure 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 opera-
tions must be ended with a Stop condition.
4.4 Dat a 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 th e 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 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
theoretically unlimited, although only the last sixteen
will be stored when doing a write operation. When an
overwri te does occur it will replace da ta in a firs t-in first-
out fashion.
4.5 Acknowledge
Each receiving device, when addressed, is required to
generate an acknowledge after the reception of each
byte. The mast er device mus t ge nera te a n ext ra c lock
pulse which is associated with this Acknowledge bit.
The device that acknowledges has to pull down the
SDA line du ring the Acknow ledge cl ock pulse in s uch 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 no t g ene rati ng an Acknow led ge bi t o n th e las t
byte that has been clocked out of the slave. In this
case, the slave must leave the data line high to enable
the maste r to gen erat e the Stop conditi on (Fi gure 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 control byte consists of a four bit control code; for
the 24C02C this is set as ‘1010’ binary for read and
write op erat ion s. Th e ne xt three bits of th e control byte
are t he C hip Sele ct b its (A 2, A1 , A0) . Th e C hip S ele ct
bits allo w th e us e of up to eigh t 24C 02C d evice s on the
same bus and are used to select which device is
accessed. The Chip Select bits in the control byte must
corresp ond to the logic lev els on the corresp onding 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 ‘0a 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 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 24C02C will select a read or
write operation.
FIGURE 5-1: CONTROL BYTE FORMAT
5.1 Contiguous Addressing Across
Multiple Devices
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 A8, A1 as address bit A9, and A2 as
address bit A10. It is not possible to write or read
across device boundaries.

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 i s a logi c low, is pl aced ont o the bu s 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 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 gener-
ates a Stop condition. This initiates the internal write
cycle, and during this time the 24C02C will not gener-
ate 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 Page Write
The write control byte, word address and the first data
byte are tr ansmitted to the 24 C02C in the same way a s
in a byte write. But instead of generating a Stop
conditi on, th e mas ter tran smit s u p to 15 addi tional dat a
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
conditi on. After th e recei pt of each word , the four lo wer
order Address Pointer bits are internally incremented
by o ne. T h e hi g her o r der f o ur bi ts of t he w o rd a d dr e ss
remains constant. If the master should transmit more
than 1 6 bytes p rior to gen erating the S top cond ition, 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 acknowl-
edge the command, but no data will be written. The
write cycle time must be observed even if the write
protection is enabled.
6.3 Write Protection
The WP pin must be tied to VCC or VSS. If tied to VCC,
the upper half of the array (080-0FF) will be write-
protected. If the WP pin is tied to VSS, then write
operations t o all addr ess locations a re allowed.
FIGURE 6-1: BYTE WRITE
FIGURE 6-2: PAGE 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 size’ ) an d end at address es that a re
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 ritte n to th e nex t page as mi ght be
expected. It is therefore necessary for the
application software to 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
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 AC K is retu rned, then the S t art bit and cont rol 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.
FIGURE 7-1: ACKNOWLEDGE
POLLING FLOW
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 one. There a re three basic types
of read operation s: curren t address re ad, ra ndom rea d,
and sequential read.
8.1 Current Address Read
The 24C02C 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
operat ion woul d acc ess da ta f rom add ress n + 1. Upo n
receipt o f the slave a ddress with the R/W bit s et 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 S top condition and the
24C02C 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 o peration, fi rst the word address m us t
be set. This is done b y sending the word address to the
24C02C as part of a write operation. After the word
address is sent, the master generat es a Start condi tion
following the acknowledge. This terminates the write
operatio n, 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 m aster wil l not a cknowledg e the tra nsfer b ut
does generate a Stop condition and the 24C02C
discontinues transmission (Figure 8-2). After this
command, the interna l address counte r will po int 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 24C02C transmits
the first data byte, the master issues an acknowledge
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).
To provide sequential reads, the 24C02C 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 FF to
address 00.
