Description
These I²C-compatible electrically erasable programmable memory (EEPROM) devices are
organized as 2048/1024/512/256/128 x 8 (M24C16, M24C08, M24C04, M24C02 and
M24C01).

I²C uses a two-wire serial interface, comprising a bidirectional data line and a clock line. The
devices carry a built-in 4-bit Device Type Identifier code (1010) in accordance with the I²C
bus definition.
The device behaves as a slave in the I²C protocol, with all memory operations synchronized
by the serial clock. Read and Write operations are initiated by a Start condition, generated
by the bus master. The Start condition is followed by a device select code and Read/Write
bit (RW) (as described in Table 3), terminated by an acknowledge bit.
th
When writing data to the memory, the device inserts an acknowledge bit during the 9 bit
time, following the bus master’s 8-bit transmission. When data is read by the bus master, the
bus master acknowledges the receipt of the data byte in the same way. Data transfers are
terminated by a Stop condition after an Ack for Write, and after a NoAck for Read.

Signal description
2.1
Serial Clock (SCL)
This input signal is used to strobe all data in and out of the device. In applications where this
signal is used by slave devices to synchronize the bus to a slower clock, the bus master
must have an open drain output, and a pull-up resistor can be connected from Serial Clock
(SCL) to V . (Figure 5 indicates how the value of the pull-up resistor can be calculated). In
CC
most applications, though, this method of synchronization is not employed, and so the pull-
up resistor is not necessary, provided that the bus master has a push-pull (rather than open
drain) output.
2.2
2.3
Serial Data (SDA)
This bidirectional signal is used to transfer data in or out of the device. It is an open drain
output that may be wire-ORed with other open drain or open collector signals on the bus. A
pull up resistor must be connected from Serial Data (SDA) to V . (Figure 5 indicates how
CC
the value of the pull-up resistor can be calculated).
Chip Enable (E0, E1, E2)
These input signals are used to set the value that is to be looked for on the three least
significant bits (b3, b2, b1) of the 7-bit device select code. These inputs must be tied to V
CC
or V , to establish the device select code as shown in Figure 4. When not connected (left
SS
floating), E0, E1, E2 are read as low (0,0,0).

2.3.1
Write Control (WC)
This input signal is useful for protecting the entire contents of the memory from inadvertent
write operations. Write operations are disabled to the entire memory array when Write
Control (WC) is driven High. When unconnected, the signal is internally read as V , and
IL
Write operations are allowed.
When Write Control (WC) is driven High, device select and address bytes are
acknowledged, data bytes are not acknowledged.

Supply voltage (VCC)
2.4.1
Operating supply voltage V
CC
Prior to selecting the memory and issuing instructions to it, a valid and stable V voltage
CC
within the specified [V (min), V (max)] range must be applied (see Table 6, Table 7 and
CC
CC
Table 8). In order to secure a stable DC supply voltage, it is recommended to decouple the
V
V
line with a suitable capacitor (usually of the order of 10 nF to 100 nF) close to the
CC
/V package pins.
CC SS
This voltage must remain stable and valid until the end of the transmission of the instruction
and, for a Write instruction, until the completion of the internal write cycle (t ).
W
2.4.2
2.4.3
Power-up conditions
The V voltage has to rise continuously from 0 V up to the minimum V operating voltage
CC
CC
defined in Table 6, Table 7 and Table 8 and the rise time must not vary faster than 1 V/µs.
Device reset
In order to prevent inadvertent write operations during power-up, a power-on-reset (POR)
circuit is included. At power-up (continuous rise of V ), the device does not respond to any
CC
instruction until V reaches the power-on-reset threshold voltage (this threshold is lower
CC
than the minimum V operating voltage defined in Table 6, Table 7 and Table 8). When
CC
V
passes over the POR threshold, the device is reset and enters the Standby Power
CC
mode. The device, however, must not be accessed until V reaches a valid and stable V
CC
CC
voltage within the specified [V (min), V (max)] range.
CC
CC
In a similar way, during power-down (continuous decrease in V ), as soon as V drops
CC
CC
below the power-on-reset threshold voltage, the device stops responding to any instruction
sent to it.
2.4.4
Power-down conditions
During power-down (continuous decrease in V ), the device must be in the Standby Power
CC
mode (mode reached after decoding a Stop condition, assuming that there is no internal
write cycle in progress).

Device operation

Device operation
The device supports the I²C protocol. This is summarized in Figure 6. Any device that sends
data on to the bus is defined to be a transmitter, and any device that reads the data to be a
receiver. The device that controls the data transfer is known as the bus master, and the
other as the slave device. A data transfer can only be initiated by the bus master, which will
also provide the serial clock for synchronization. The device is always a slave in all
communication.
3.1
3.2
Start condition
Start is identified by a falling edge of Serial Data (SDA) while Serial Clock (SCL) is stable in
the High state. A Start condition must precede any data transfer command. The device
continuously monitors (except during a Write cycle) Serial Data (SDA) and Serial Clock
(SCL) for a Start condition.
Stop condition
Stop is identified by a rising edge of Serial Data (SDA) while Serial Clock (SCL) is stable
and driven High. A Stop condition terminates communication between the device and the
bus master. A Read command that is followed by NoAck can be followed by a Stop condition
to force the device into the Standby mode. A Stop condition at the end of a Write command
triggers the internal Write cycle.
3.3
3.4
Acknowledge bit (ACK)
The acknowledge bit is used to indicate a successful byte transfer. The bus transmitter,
whether it be bus master or slave device, releases Serial Data (SDA) after sending eight bits
th
of data. During the 9 clock pulse period, the receiver pulls Serial Data (SDA) Low to
acknowledge the receipt of the eight data bits.
Data input
During data input, the device samples Serial Data (SDA) on the rising edge of Serial Clock
(SCL). For correct device operation, Serial Data (SDA) must be stable during the rising edge
of Serial Clock (SCL), and the Serial Data (SDA) signal must change only when Serial Clock
(SCL) is driven Low.

3.5
Memory addressing
To start communication between the bus master and the slave device, the bus master must
initiate a Start condition. Following this, the bus master sends the device select code, shown
in Table 3 (on Serial Data (SDA), most significant bit first).
The device select code consists of a 4-bit Device Type Identifier, and a 3-bit Chip Enable
“Address” (E2, E1, E0). To address the memory array, the 4-bit Device Type Identifier is
1010b.
Each device is given a unique 3-bit code on the Chip Enable (E0, E1, E2) inputs. When the
device select code is received, the device only responds if the Chip Enable Address is the
same as the value on the Chip Enable (E0, E1, E2) inputs. However, those devices with
larger memory capacities (the M24C16, M24C08 and M24C04) need more address bits. E0
is not available for use on devices that need to use address line A8; E1 is not available for
devices that need to use address line A9, and E2 is not available for devices that need to
use address line A10 (see Figure 2 and Table 3 for details). Using the E0, E1 and E2 inputs,
up to eight M24C02 (or M24C01), four M24C04, two M24C08 or one M24C16 devices can
be connected to one I²C bus. In each case, and in the hybrid cases, this gives a total
memory capacity of 16 Kbits, 2 KBytes (except where M24C01 devices are used).
th
The 8 bit is the Read/Write bit (RW). This bit is set to 1 for Read and 0 for Write operations.
If a match occurs on the device select code, the corresponding device gives an
th
acknowledgment on Serial Data (SDA) during the 9 bit time. If the device does not match
the device select code, it deselects itself from the bus, and goes into Standby mode.

Write operations
Following a Start condition the bus master sends a device select code with the Read/Write
bit (RW) reset to 0. The device acknowledges this, as shown in Figure 8, and waits for an
address byte. The device responds to the address byte with an acknowledge bit, and then
waits for the data byte.
When the bus master generates a Stop condition immediately after a data byte’s Ack bit (in
th
the “10 bit” time slot), either at the end of a Byte Write or a Page Write, the internal write
cycle is triggered. A Stop condition at any other time slot does not trigger the internal write
cycle.
During the internal Write cycle, Serial Data (SDA) and Serial Clock (SCL) are ignored, and
the device does not respond to any requests.
3.6.1
Byte Write
After the device select code and the address byte, the bus master sends one data byte. If
the addressed location is Write-protected, by Write Control (WC) being driven High (during
the period from the Start condition until the end of the address byte), the device replies to
the data byte with NoAck, as shown in Figure 7, and the location is not modified. If, instead,

Device operation
M24C16, M24C08, M24C04, M24C02, M24C01
the addressed location is not Write-protected, the device replies with Ack. The bus master
terminates the transfer by generating a Stop condition, as shown in Figure 8.
3.6.2
Page Write
The Page Write mode allows up to 16 bytes to be written in a single Write cycle, provided
that they are all located in the same page in the memory: that is, the most significant
memory address bits are the same. If more bytes are sent than will fit up to the end of the
page, a condition known as ‘roll-over’ occurs. This should be avoided, as data starts to
become overwritten in an implementation dependent way.
The bus master sends from 1 to 16 bytes of data, each of which is acknowledged by the
device if Write Control (WC) is Low. If the addressed location is Write-protected, by Write
Control (WC) being driven High (during the period from the Start condition until the end of
the address byte), the device replies to the data bytes with NoAck, as shown in Figure 7,
and the locations are not modified. After each byte is transferred, the internal byte address
counter (the 4 least significant address bits only) is incremented. The transfer is terminated
by the bus master generating a Stop condition.

Minimizing system delays by polling on ACK
During the internal Write cycle, the device disconnects itself from the bus, and writes a copy
of the data from its internal latches to the memory cells. The maximum Write time (tw) is
shown in Table 15, but the typical time is shorter. To make use of this, a polling sequence
can be used by the bus master.
The sequence, as shown in Figure 9, is:
●
Initial condition: a Write cycle is in progress.
●
Step 1: the bus master issues a Start condition followed by a device select code (the
first byte of the new instruction).
●
Step 2: if the device is busy with the internal Write cycle, no Ack will be returned and
the bus master goes back to Step 1. If the device has terminated the internal Write
cycle, it responds with an Ack, indicating that the device is ready to receive the second
part of the instruction (the first byte of this instruction having been sent during Step 1).

1. The seven most significant bits of the device select code of a Random Read (in the 1st and 3rd bytes) must
be identical.
3.7
Read operations
Read operations are performed independently of the state of the Write Control (WC) signal.
The device has an internal address counter which is incremented each time a byte is read.
3.7.1
Random Address Read
A dummy Write is first performed to load the address into this address counter (as shown in
Figure 10) but without sending a Stop condition. Then, the bus master sends another Start
condition, and repeats the device select code, with the Read/Write bit (RW) set to 1. The
device acknowledges this, and outputs the contents of the addressed byte. The bus master
must not acknowledge the byte, and terminates the transfer with a Stop condition.

Device operation
3.7.2
Current Address Read
For the Current Address Read operation, following a Start condition, the bus master only
sends a device select code with the Read/Write bit (RW) set to 1. The device acknowledges
this, and outputs the byte addressed by the internal address counter. The counter is then
incremented. The bus master terminates the transfer with a Stop condition, as shown in
Figure 10, without acknowledging the byte.
3.7.3
Sequential Read
This operation can be used after a Current Address Read or a Random Address Read. The
bus master does acknowledge the data byte output, and sends additional clock pulses so
that the device continues to output the next byte in sequence. To terminate the stream of
bytes, the bus master must not acknowledge the last byte, and must generate a Stop
condition, as shown in Figure 10.
The output data comes from consecutive addresses, with the internal address counter
automatically incremented after each byte output. After the last memory address, the
address counter ‘rolls-over’, and the device continues to output data from memory address
00h.
3.7.4
Acknowledge in Read mode
For all Read commands, the device waits, after each byte read, for an acknowledgment
th
during the 9 bit time. If the bus master does not drive Serial Data (SDA) Low during this
time, the device terminates the data transfer and switches to its Standby mode.

I²C specification that the input signal rise and fall times be more than 20 ns and less than 300 ns when
fC < 400 kHz.
5. To avoid spurious Start and Stop conditions, a minimum delay is placed between SCL=1 and the falling or
rising edge of SDA.
6. tCLQV is the time (from the falling edge of SCL) required by the SDA bus line to reach either 0.3VCC or
0.7VCC, assuming that Rbus × Cbus time constant is within the values specified in Figure 5.
