Stop Data Transfer (C)
2.0
FUNCTIONAL DESCRIPTION
The 24C01B/02B supports a bi-directional two 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 gener-
ates the START and STOP conditions, while the
24C01B/02B works as slave. Both master and slave
can operate as transmitter or receiver but the master
device determines which mode is activated.
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.
3.4
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 clock pulse per
bit of data.
3.0
BUS CHARACTERISTICS
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.
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 3-1).
3.5
Acknowledge
Each receiving device, when addressed, is obliged 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.
3.1
Bus Not Busy (A)
Both data and clock lines remain HIGH.
3.2
Start Data Transfer (B)
Note: The 24C01B/02B does not generate any
acknowledge bits if an internal program-
ming cycle is in progress.
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 condi-
tion.
The device that acknowledges has to pull down the
SDA line during the acknowledge clock pulse in such a

Device Address

WRITE OPERATION
After generating a START condition, the bus master
transmits the slave address consisting of a 4-bit device
code (1010) for the 24C01B/02B, followed by three
don't care bits.
4.1
Byte Write
Following the start signal from the master, the device
code (4 bits), the don't care bits (3 bits), and the R/W bit
which is a logic low is placed onto the bus by the master
transmitter. This indicates to the addressed slave
receiver that a byte with a word address will follow after
it has generated an acknowledge bit during the ninth
clock cycle. Therefore the next byte transmitted by the
master is the word address and will be written into the
address pointer of the 24C01B/02B. After receiving
another acknowledge signal from the 24C01B/02B the
master device will transmit the data word to be written
into the addressed memory location. The 24C01B/02B
acknowledges again and the master generates a stop
condition. This initiates the internal write cycle, and
during this time the 24C01B/02B will not generate
acknowledge signals (Figure 4-1).
The eighth bit of slave address determines if the master
device wants to read or write to the 24C01B/02B
(Figure 3-2).
The 24C01B/02B monitors the bus for its correspond-
ing slave address all the time. It generates an acknowl-
edge bit if the slave address was true and it is not in a
programming mode.

Page Write
The write control byte, word address and the first data
byte are transmitted to the 24C01B/02B in the same
way as in a byte write. But instead of generating a stop
condition the master transmits up to eight data bytes to
the 24C01B/02B 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 three lower order address
pointer bits are internally incremented by one. The
higher order five bits of the word address remains con-
stant. If the master should transmit more than eight
words 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 4-2).

ACKNOWLEDGE POLLING
7.0
READ OPERATION
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 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 5-1 for flow diagram.
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.
7.1
Current Address Read
The 24C01B/02B contains an address counter that
maintains the address of the last word accessed, inter-
nally incremented by one. Therefore, if the previous
access (either a read or write operation) was to
address n, the next current address read operation
would access data from address n + 1. Upon receipt of
the slave address with R/W bit set to one, the 24C01B/
02B issues an acknowledge and transmits the eight bit
data word. The master will not acknowledge the trans-
fer but does generate a stop condition and the 24C01B/
02B discontinues transmission (Figure 7-1).
FIGURE 5-1: ACKNOWLEDGE POLLING
FLOW
Send
Write Command
7.2
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
24C01B/02B 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 24C01B/02B 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 24C01B/02B
discontinues transmission (Figure 7-2).

Sequential Read

Acknowledge
Sequential reads are initiated in the same way as a ran-
dom read except that after the 24C01B/02B transmits
the first data byte, the master issues an acknowledge
as opposed to a stop condition in a random read. This
directs the 24C01B/02B to transmit the next sequen-
tially addressed 8-bit word (Figure 7-3).

YES
Next
Operation
To provide sequential reads the 24C01B/02B 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.
6.0
WRITE PROTECTION
The 24C01B/02B can be used as a serial ROM when
the WP pin is connected to VCC. Programming will be
inhibited and the entire memory will be write-protected.
7.4
Noise Protection
The 24C01B/02B employs a VCC threshold detector
circuit which 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 which suppress noise spikes to assure proper
device operation even on a noisy bus.

PIN DESCRIPTIONS
This pin must be connected to either VSS or VCC.
8.1
Serial Data
If tied to VSS, normal memory operation is enabled
(read/write the entire memory).
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 VCC (typically 10 K¾ for 100 kHz).
If tied to VCC, WRITE operations are inhibited. The
entire memory will be write-protected. Read operations
are not affected.
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.
This feature allows the user to use the 24C01B/02B as
a serial ROM when WP is enabled (tied to VCC).
8.2
SCL Serial Clock
This input is used to synchronize the data transfer from
and to the device.
