Description
The Atmel AT24MAC402 and AT24MAC602 provides 2048 bits of Serial Electrically-Erasable Programmable Read-Only
Memory (EEPROM) organized as 256 words of eight bits each and is accessed via an I2C-compatible (2-wire) serial
interface. In addition, AT24MAC402/602 incorporates an easy and inexpensive method to obtain a globally unique MAC
or EUI address (EUI-48 or EUI-64). AT24MAC402 is an EUI-48 compatible device that contains a 48-bit EUI address,
and AT24MAC602 is an EUI-64 compatible device that contains a 64-bit EUI address.
The EUI-48 and EUI-64 addresses can be assigned as the actual physical address of a system hardware device or node
or it can be assigned to a software instance. These addresses are factory programmed by Atmel and permanently write
protected in an extended memory block located outside of the standard 2-Kbit bit memory array.
In addition, the AT24MAC402/602 provides the value added feature of a factory-programmed, guaranteed unique 128-bit
serial number located in the extended memory block (same area as the EUI address values). The serial number is Atmel
factory-programmed and permanently write protected. This 128-bit serial number is compatible with all AT24CS,
AT93CS, and AT25S family serial numbers, therefore, providing guaranteed unique serial numbers for any application
that is also using Atmel Serial EEPROMs.
The first-half of the AT24MAC402/602 incorporates a permanent and a reversible software write protection feature while
a hardware write protect feature for the entire array is available via an external pin. The permanent software write
protection is enabled by sending a special command to the device. This protection cannot be reversed once executed.
However, the reversible software write protection can be reversed by sending and executing a special command. The
hardware write protection is controlled by the WP pin state and can be used to protect the entire array regardless of
whether or not the software write protection has been enabled. The software and hardware write protection features
allow the user the flexibility to protect no portion of the memory, the first-half of the memory, or the entire memory array
depending on the specific needs of the application.
The device is optimized for use in many industrial and commercial applications where low-power and low-voltage
operations are essential. The AT24MAC402/602 is available in space saving 8-lead JEDEC SOIC, 8-lead TSSOP,
8-pad UDFN, and 5-lead SOT23 packages. Both devices operate across a wide supply voltage range from
1.7V to 5.5V VCC.

Pin Description
Serial Clock (SCL): The SCL input is used to positive edge clock data into each EEPROM device and negative edge
clock data out of each device.
Serial Data (SDA): The SDA pin is bidirectional for serial data transfer. This pin is open-drain driven and may be
wire-ORed with any number of other open-drain or open collector devices.
Device Addresses (A0, A1, A2): The A0, A1, and A2 pins are device address inputs that are hard wired for the
AT24MAC402/602. As many as eight 2K devices may be addressed on a single bus system. Device addressing is
discussed in detail under “Device Addressing” on page 10.
Write Protect (WP): The AT24MAC402/602 has a Write Protect pin that provides hardware data protection. When the
Write Protect pin is connected to ground (GND), normal Read/Write operations to the full array are possible. When the
Write Protect pin is connected to VCC, all write operations to the memory are inhibited, but read operations are still
possible. However, due to capacitive coupling that may appear during customer applications, Atmel recommends always
connecting the WP pins to a known state. When using a pull-up resistor, Atmel recommends using 10k or less. The
write protection operation is summarized in Table 2-1 below.

Memory Organization
Atmel AT24MAC402/602, 2K Serial EEPROM: The 2-Kbit memory array is internally organized as 16 pages of 16 bytes
of EEPROM each. Random word addressing requires a 8-bit data word address.
EUI Address and Serial Number: The 48-bit EUI address in the AT24MAC402 and the 64-bit EUI address in the
AT24MAC602 are located in the extended memory block. In addition, the serial number data is also located in the
extended memory block as shown below in Figure 3-1. These EUI-48 or EUI-64 addresses are stored in a dedicated
read-only EEPROM memory block located outside the standard 2K memory array as shown below. This means the full
standard 2-Kbit EEPROM array is available for use as opposed to solutions where only half of the EEPROM memory
array is available for application usage.

The EUI-48 and EUI-64 address fields contain either six or eight bytes respectively. The first three bytes of the EUI
read-only address field are called the Organizationally Unique Identifier (OUI) and the IEEE Registration Authority has
assigned FCC23Dh as the Atmel, OUI.
Following the OUI, the remaining bytes are called the Extension Identifier and will be either three bytes or five bytes
depending on if it is an EUI-48 address (AT24MAC402) or EUI-64 address (AT24MAC602). Atmel generates this unique
24-bit/40-bit data value along with the OUI to guarantee a globally unique EUI address value and programs it at the
factory before permanently locking the extended memory region.

EUI-48 Support
The EUI-48 address is stored in the last six bytes of the AT24MAC402’s extended memory block as shown in Table 3-1.

Using an EUI-48 Value in an EUI-64 Application: An EUI-64 compatible value can be generated from the EUI-48 value
contained in the AT24MAC402 by concatenating the 24-bit OUI, an FFFEh data value, and the 24-bit Extension
Identifier. This is commonly referred to as an Encapsulated EUI-48 value. However, Atmel recommends using the
AT24MAC602 which contains a true EUI-64 value so that post read processing is not required by the application.
3.2
EUI-64 Support
For applications that utilize an EUI-64 standard, the EUI-64 address is stored in the last eight bytes of the
AT24MAC602’s extended memory block. Similar to EUI-48, the EUI-64 standard consists of the same three byte OUI
coupled with a five byte extension identifier (see Table 3-2). Atmel generates this unique 40-bit data value coupled with
the OUI to guarantee a globally unique 64-bit EUI value and requires no additional data manipulation like other solutions
where the application must manually insert a two byte FFFEh value in between the OUI and Extension Identifier. For
information on how to read the EUI read protocol, see “Device Addressing” on page 10 and “Read Operations” on page
15.

Device Operation
Clock and Data Transitions: The SDA pin is normally pulled high with an external component such as a pull-up resistor.
Data on the SDA pin may change only during SCL low time periods (see Figure 4-4 on page 9). Data changes during
SCL high periods will indicate a Start or Stop condition as defined below.
Start Condition: A high-to-low transition of SDA with SCL high is a Start condition which must precede any other
command (see Figure 4-5 on page 9).
Stop Condition: A low-to-high transition of SDA with SCL high is a Stop condition. After a read sequence, the stop
command will place the EEPROM in a standby power mode (see Figure 4-5 on page 9).
Acknowledge: All addresses and data words are serially transmitted to and from the EEPROM in 8-bit words. The
EEPROM sends a zero to acknowledge that it has received each word. This happens during the ninth clock cycle.
Standby Mode: The AT24MAC402/602 features a low-power standby mode which is enabled upon

Power-up or

After the receipt of the Stop bit and the completion of any internal operations.
2-Wire Software Reset: After an interruption in protocol, power loss or system reset, any 2-wire part can be reset by
following these steps:
1.
Create a start bit condition.
2.
Clock nine cycles.
3.
Create another start bit followed by Stop bit condition as shown below.

Device Addressing
Standard EEPROM Access: The 2K EEPROM requires an 8-bit device address word following a start condition to
enable the chip for a read or write operation (see Table 8-1 on page 16).
The device address word consists of a mandatory one-zero sequence for the first four most-significant bits ‘1010’(Ah)
for normal read and write operations and ‘0110’ (6h) for writing to the Software Write Protect Register.
The next three bits in the protocol sequence are the A2, A1, and A0 device address bits. These three bits must match
their corresponding hard-wired input pins A2, A1, and A0 in order for the part to acknowledge.
The eighth bit of the device address is the read/write operation select bit. A read operation is initiated if this bit is high,
and a write operation is initiated if this bit is low. Upon a compare of the device address, the EEPROM will output a zero.
If a compare is not made, the device will return to a standby state. The device will not acknowledge if the Write Protect
Register has been programmed and the control code is ‘0110’(6h).
Serial Number Access: The AT24MAC402/602 incorporates an extended memory block containing a
factory-programmed 128-bit serial number. Access to this memory location is obtained by beginning the device address
word with a ‘1011’(Bh) sequence. The behavior of the next three bits (A2, A1, and A0) remain the same as during a
standard memory addressing sequence.
The eighth bit of the device address needs to be set to a one to read the serial number. A zero in this bit position, other
than during a dummy write sequence to set the address pointer, will result in a unknown condition and behavior. Writing
or altering the 128-bit serial number is not possible as it is permanently write protected. Further specific protocol is
needed to address the serial number feature of the part. For more details on accessing this special feature, See “Read
Operations” on page 15.
EUI Address Access: The AT24MAC402/602 utilizes an extended memory block containing a factory-programmed
read-only EUI-48 or EUI-64 address respectively. Access to this memory block is obtained by beginning the device
address word with a ‘1011’ (Bh) sequence. The behavior of the next three bits (A2, A1, and A0) remain the same as
during a standard memory addressing sequence.
The eighth bit of the device address needs to be set to a one to read the EUI address. A zero in this bit position, other
than during a dummy write sequence to set the address pointer, will result in a unknown condition and behavior.
Attempting to write or alter the EUI address is not possible as it is permanently write protected. Further specific protocol
is needed to address this feature of the part. For more details on accessing this special feature, see “Read Operations”
on page 15.

Write Operations
Byte Write: A Byte Write operation requires an 8-bit data word address following the device address word and
acknowledgment. Upon receipt of this address, the EEPROM will again acknowledge or respond with a zero and then
clock in the first 8-bit data word. Following receipt of the 8-bit data word, the EEPROM will output a zero and the
addressing device, such as a microcontroller, must terminate the write sequence with a Stop condition. At this time, the
EEPROM enters an internally-timed write cycle, tWR, to the nonvolatile memory. All inputs are disabled during this write
cycle and the EEPROM will not respond until the write is complete (see Figure 8-1 on page 16). The device will
acknowledge a write command, but not write the data if the software or hardware write protection has been enabled. The
write cycle time must be observed even when the write protection is enabled.
Page Write: The AT24MAC402/602 is capable of a 16-byte Page Write. A Page Write is initiated by the same method as
a Byte Write, but the microcontroller does not send a Stop condition after the first data word is clocked in. Instead, after
the EEPROM acknowledges receipt of the first data word, the microcontroller can transmit up to fifteen more data words.
The EEPROM will respond with a zero after each data word received. The microcontroller must terminate the page write
sequence with a Stop condition (see Figure 8-2 on page 17).
The lower four data word address bits are internally incremented following the receipt of each data word. The higher data
word address bits are not incremented, retaining the memory page row location. When the internally generated word
address reaches the page boundary, the next byte is placed at the beginning of the same page. If more than sixteen data
words are transmitted to the EEPROM, the data word address will roll-over and previous data will be overwritten. The
address roll-over during write is from the last byte of the current page to the first byte of the same page. The device will
acknowledge a write command, but will not write the data if the software or hardware write protection has been enabled.
The write cycle time must be observed even when the write protection is enabled.
Acknowledge Polling: Once the internally-timed write cycle has started and the EEPROM inputs are disabled,
acknowledge polling can be initiated. This involves sending a Start condition followed by the device address word. The
read/write bit is representative of the operation desired. Only if the internal write cycle has completed will the EEPROM
respond with a zero allowing the read or write sequence to continue.
7.
Write Protection
Once enabled, the Software Write Protection write protects only the first-half of the array (00h - 7Fh) while the hardware
write protection, via the WP pin, is used to protect the entire array (see Table 7-1 on page 13).
Permanent Software Write Protection (PSWP): The Permanent Software Write Protection is enabled by sending a
command to the device, similar to a normal write command, which programs the Permanent Write Protect Register. This
must be done with the WP pin low. The Write Protect Register is programmed by sending a write command with the
device address of ‘0110’(6h) instead of ‘1010’ (Ah) with the address and data bit(s) being don’t cares (see Figure 7-1
on page 12). The write cycle time must be observed. Once the permanent software write protection has been enabled,
the device will no longer acknowledge the ‘0110’ (6h) control byte and cannot be reversed even if the device is
powered down. The Permanent Software Write Protection can only be invoked on a SOT23 packaged device with the
A2, A1, and A0 bits set to zero.
Reversible Software Write Protection (RSWP): The Reversible Software Write Protection is enabled by sending a
command to the device, similar to a normal write command, which programs the Reversible Write Protect Register. This
must be done with the WP pin low. The Reversible Write Protect Register is programmed by sending a write command
‘01100010’(62h) with pins A2 and A1 tied to ground or not connected and the A0 pin connected to VHV (see Figure 7-2
Atmel AT24MAC402/602 [DATASHEET]
8807A–SEEPR–6/12

on page 12 and Table 7-2 on page 13). The Reversible Write Protection Register or Write Protection can be reversed by
sending a command ‘01100110’(66h) with the A2 pin tied to ground or no connect, the A1 pin tied to VCC and the A0 pin
tied to VHV (see Figure 7-3 on page 12 and Table 7-2 on page 13). Due to the unavailability of the A2, A1, and A0 pins, the
Reversible Software Write Protection function is not available on the SOT23 package.
Hardware Write Protection: The WP pin can be connected to VCC, GND, or left floating. Connecting the WP pin to VCC
will write protect the entire array regardless of whether or not the Software Write Protection has been enabled or invoked
(see Table 7-3 on page 13 and Table 7-4 on page 14). The Software Write Protection Register cannot be programmed
when the WP pin is connected to VCC. If the WP pin is connected to GND or left floating, the write protection mode is
determined by the status of the Software Write Protect Register.

Read Operations
Read operations are initiated the same way as write operations with the exception that the read/write select bit in the
device address word is set to one. There are three types of read operations:

Current Address Read

Random Address Read

Sequential Read
Current Address Read: The internal data word address counter maintains the last address accessed during the last
read or write operation, incremented by one. This address stays valid between operations as long as VCC to the chip is
maintained. The address roll-over during read is from the last byte of the last memory page to the first byte of the first
page.
Once the device address with the read/write select bit set to one is clocked in and acknowledged by the EEPROM, the
current address data word is serially clocked out. To end the command, the microcontroller does not respond with a zero
but does generate a Stop condition in the subsequent clock cycle (see Figure 8-3 on page 17).
Random Read: A random read requires a dummy byte write sequence to load in the data word address. Once the
device address word and data word address are clocked in and acknowledged by the EEPROM, the microcontroller must
generate another Start condition. The microcontroller now initiates a current address read by sending a device address
with the read/write select bit high. The EEPROM acknowledges the device address and serially clocks out the data word.
To end the random read sequence, the microcontroller does not respond with a zero but does generate a Stop condition
in the subsequent clock cycle (see Figure 8-4 on page 17).
Sequential Read: Sequential reads are initiated by either a current address read or a random address read. After the
microcontroller receives a data word, it responds with an acknowledge. As long as the Serial EEPROM receives an
acknowledge, it will continue to increment the data word address and serially clock out sequential data words. When the
memory address limit is reached, the data word address will “roll over” and the sequential read will continue. The
sequential read operation is terminated when the microcontroller does not respond with a zero but does generate a
following Stop condition in the subsequent clock cycle (see Figure 8-5 on page 17).
Serial Number Read: Reading the serial number is similar to the sequential read sequence but requires use of a
different device address value as shown in Figure 8-6 on page 18, followed by a dummy write, and the use of a specific
word address.
Note:
The entire 128-bit value must be read from the starting address of the serial number block to guarantee a
unique number.
Since the address pointer of the device is shared between the regular EEPROM array and the serial number block, a
dummy write sequence should be performed to ensure the address pointer is set to zero. Random reads of the serial
number block are supported but if the previous operation was to the EEPROM array, the address pointer will retain the
last location accessed, incremented by one. Reading the serial number from a location other than the first address of the
block will not result in a unique serial number.
Additionally, the most-significant four bits of the word address must be ‘1000’(8h). Thus, if the application desires to
read the pre-programmed serial number, then the corresponding word address input would be 80h. If a word address
other than 80h is used, then the device will output undefined data.
EUI Address Read: Reading the EUI address is very similar to the Serial Number read sequence with the exceptions of
the starting word address and the amount of data bytes clocked out (see Figure 8-7 on page 18). The EUI read sequence
requires use of the device address values as shown in Table 8-1 on page 16, followed by a dummy write, and the use of
a specific word address from Figure 3-1 on page 7 for EUI-48 standard or Figure 3-2 on page 7 for EUI-64 standard.
Note:
The entire six byte (EUI-48) or eight byte (EUI-64) values must be read from the respective starting address
of either 9Ah (for EUI-48) or 98h (for EUI-64) to guarantee a unique EUI data value.
Atmel AT24MAC402/602 [DATASHEET]
8807A–SEEPR–6/12
15
Since the address pointer of the device is shared between the regular EEPROM array, the serial number block, and the
EUI block, a dummy write sequence should be performed to ensure the address pointer is set to the correct starting EUI48 or EUI-64 address. Random reads of the EUI block are supported, but if the previous operation was to the EEPROM
array or to the serial number block, the address pointer will retain the last location accessed, incremented by one.
Reading the EUI data from a location other than the correct starting EUI address of the block will not result in a unique
EUI data value.
Additionally, the most-significant four bits of the word address must be ‘1001’(9h). Therefore, if the application desires
to read the pre-programmed EUI value, then the corresponding word address input would be 9Ah in the AT24MAC402
and 98h for the AT24MAC602. If a word address other than 9Ah or 98h respectively is used, the device will output
undefined data.
Once the EUI block of six or eight bytes of data have been clocked out of the device, the EUI read operation will end
when the microcontroller does not respond with a zero or acknowledge, but then creates a Stop condition. It is important
to note that the data word address will not roll-over back to the beginning of the respective EUI starting address. If the
read operation continues past the last EUI data value, the data word address will roll-over back to the beginning of the
extended memory block where the 128-bit serial number will begin to read out. Therefore, every EUI read sequence
attempt requires a valid starting address in the dummy write sequence as shown in Figure 8-7 on page 18.
Checking the Permanent Write Protect Register (PSWP) Status: Determining the status of the Permanent Write
Protect Register can be accomplished by sending a similar command to the device as was used when programming the
register, except the R/W bit must be set to one. If the device responds with an acknowledge, the Permanent Write Protect
Register has not been programmed; otherwise, it has been programmed and the first-half of the array is permanently
write protected.
Checking the Reversible Write Protect Register (RSWP) Status: Determining the status of the Reversible Write
Protect Register can be accomplished by sending a similar command to the device as was used when programming the
register, except the R/W bit must be set to one. If the device returns an acknowledge, the Reversible Write Protect
Register has not been programmed; otherwise, it has been programmed and the first-half of the array is write protected,
but remains reversible.
