Description
The Atmel® AT24CS01 and AT24CS02 provides 1024/2048 bits of Serial Electrically Erasable and Programmable
Read-only Memory (EEPROM) organized as 128/256 words of eight bits each. The device is optimized for use in many
industrial and commercial applications where low-power and low-voltage operation are essential. The AT24CS01/02 is
available in space-saving, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-pad UDFN and 5-lead SOT23 packages and is
accessed via a 2-wire serial interface. In addition, both devices fully operate from 1.7V to 5.5V VCC.
The AT24CS01/02 provides the additional feature of a factory programmed, guaranteed unique 128-bit serial number,
while maintaining all of the traditional features available in the 1-Kbit or 2-Kbit Serial EEPROM. The time consuming step
of performing and ensuring true serialization of product on a manufacturing line can be removed from the production flow
by employing the CS Series Serial EEPROM. The 128-bit serial number is programmed and permanently locked from
future writing during the Atmel production process. Further, this 128-bit location does not consume any of the user
read/write area of the 1-Kbit or 2-Kbit Serial EEPROM. The uniqueness of the serial number is guaranteed across the
entire CS Series of Serial EEPROMs, regardless of the size of the memory array or the type of interface protocol. This
means that as an application's needs for memory size or interface protocol evolve in future generations, any previously
deployed serial number from any Atmel CS Series Serial EEPROM part will remain valid.

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/Page Addresses (A2, A1, A0): The A2, A1 and A0 pins are device address inputs that are hard wired for the
AT24CS01/02. As many as eight 1-Kbit or 2-Kbit devices may be addressed on a single bus system. For more detail, see
section, “Device Addressing” on page 10.
Write Protect (WP): AT24CS01/02 has a Write Protect (WP) 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.
This operation is summarized in Table 5-1 below.

Device Operation
Clock and Data Transitions: The SDA pin is normally pulled high with an external device. Data on the SDA pin may
change only during SCL low time periods (see Figure 7-4 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 7-5 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 7-5 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 AT24CS01/02 features a low-power standby mode which is enabled upon power-up as well as 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 in Figure 7-1.
The device is ready for next communication after above steps have been completed.

Device Addressing
Standard EEPROM Access: The 1K and 2K EEPROM device requires an 8-bit device address word following a Start
condition to enable the chip for a read or write operation.
The device address word consists of a mandatory ‘1010’ (Ah) sequence for the first four most significant bits as shown
in Figure 10-1 on page 12. This is common to all Serial EEPROM devices.
The next three bits are the A2, A1, and A0 device address bits for the 1K and 2K EEPROM. These three bits must
compare to 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 valid compare of the device address with hard-wired input pins A2, A1, and A0, the EEPROM will output a zero. If
a compare is not successfully made, the chip will return to a standby state.
Serial Number Access: The AT24CS01 and AT24CS02 utilizes a separate 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 EEPROM addressing
sequence. These three bits must compare to their corresponding hard-wired input pins A2, A1, and A0 in order for the part
to acknowledge.
The eighth bit of the device address needs 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 data read from the part. Writing
or altering the 128-bit serial number is not possible.
Further specific protocol is needed to read the serial number from of the device. See Read Operations on page 11 for
more details on accessing the special feature.
9.
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 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 10-2 on page 12).
Page Write: The 1K and 2K EEPROM are capable of an 8-byte Page Write. A Page Write is initiated in the same way 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 seven 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 10-3 on page 12).
The data word address lower three 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 subsequent byte loaded will be placed at the beginning of the same page.
If more than eight data words are transmitted to the EEPROM, the data word address will roll-over and previously loaded
data will be overwritten.
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 next read or write sequence to begin.

Read Operations
Read operations are initiated in 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 four read operations:

Current Address Read

Random Address Read

Sequential Read

Serial Number 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 the chip power 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. The address roll-over during write is from the last byte of the current page to the first byte of the same 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. The microcontroller does not respond with an zero but does generate a
following Stop condition (see Figure 10-4 on page 12).
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.
The microcontroller does not respond with a zero but does generate a following Stop condition (see Figure 10-5 on page
13).
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 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 (see Figure 10-6 on page 13).
Serial Number Read: Reading the serial number is similar to the sequential read sequence but requires use of the
device address seen in Figure 10-1 on page 12, a dummy write, and the use of 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 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
access location, incremented by one. Reading the serial number from a location other than the initial address of the block
will not result in a unique serial number.
Additionally, the word address must begin with a ‘10’ sequence regardless of the intended address. If a word address
other than ‘10’ is used, then the device will output undefined data.
Example:
If the application desires to read the first byte of the serial number, the word address input would need to be
80h.
When the end of the 128-bit serial number is reached (16 bytes of data), the data word address will roll-over back to the
beginning of the 128-bit serial number. The Serial Number Read operation is terminated when the microcontroller does
not respond with an zero (ACK) and instead issues a Stop condition (see Figure 10-7 on page 13).
