PIN DESCRIPTIONS

2.1

SDA Serial Data

This is a bi-directional 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 V

(typical 10 k

for 100 kHz, 2 k

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 condi-
tions.

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 cor-
responding 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. These inputs must be connected to either V

2.4

This is the hardware write protect pin. It must be tied to
V

or V

. 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 V

threshold detector circuit

which disables the internal erase/write logic if the V

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 DESCRIPTION

The 24C02C supports a bi-directional 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 which 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 trans-
mitter or receiver but the master device determines
which mode is activated.

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)

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.

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 six-
teen will be stored when doing a write operation. When
an overwrite does occur it will replace data in a first 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 master device must generate an extra clock
pulse which is associated with this acknowledge bit.

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).

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 one a read operation is
selected, and when set to a zero 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 appropri-
ate 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 add-
ing 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.

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 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 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 transmitted to the 24C02C in the same way as
in a byte write. But instead of generating a stop condi-
tion, 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 con-
stant. 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 writ-
ten. 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 V

or V

. If tied to V

the upper half of the array (080-0FF) will be write pro-
tected. If the WP pin is tied to V

, then write opera-

tions to all address locations are allowed.

FIGURE 6-1:

BYTE WRITE

FIGURE 6-2:

PAGE WRITE

Note:

Page write operations are limited to writing
bytes within a single physical page, regard-
less 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 neces-
sary 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 com-
mand has been issued from the master, the device ini-
tiates the internally timed write cycle. ACK polling can
be initiated immediately. This involves the master send-
ing 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 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 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 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 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).

8.2

Random Read

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 dis-
continues transmission (Figure 8-2). After this com-
mand, the internal address counter will point 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 ran-
dom 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.
