Description
The AT24C11 provides 1024 bits of serial electrically erasable and programmable
read only memory (EEPROM) organized as 128 words of 8 bits each. The device is
optimized for use in many industrial and commercial applications where low power
and low voltage operation are essential. The AT24C11 is available in space saving
8-lead PDIP, 8-lead JEDEC SOIC, 5-lead SOT23 and 8-lead TSSOP packages and is
accessed via a two-wire serial interface. In addition, the entire family is available in
2.7V (2.7V to 5.5V) and 1.8V (1.8V to 5.5V) versions.

1. 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.

3. 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 3-3 on
page 7). 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 3-4 on page 7).
STOP CONDITION: A low-to-high transition of SDA with SCL high is a stop condition which ter-
minates all communications. After a read sequence, the stop command will place the EEPROM
in a standby power mode (see Figure 3-4 on page 7).
ACKNOWLEDGE: All addresses and data words are serially transmitted to and from the
EEPROM in 8-bit words. Any device on the system bus receiving data (when communicating
with the EEPROM) must pull the SDA bus low to acknowledge that it has successfully received
each word. This must happen during the ninth clock cycle after each word received and after all
other system devices have freed the SDA bus. The EEPROM will likewise acknowledge by pull-
ing SDA low after receiving each address or data word (see Figure 3-5 on page 7).
STANDBY MODE: The AT24C11 features a low power standby mode which is enabled: (a)
upon power-up and (b) after the receipt of the STOP bit and the completion of any internal
operations.
MEMORY RESET: After an interruption in protocol, power loss or system reset, any 2-wire part
can be reset by following these steps:
(a) clock up to 9 cycles, (b) look for SDA high in each cycle while SCL is high and then (c) create
a start condition as SDA is high.

4. Write Operations
BYTE WRITE: Following a start condition, a write operation requires a 7-bit data word address
and a low write bit. 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
to the nonvolatile memory. All inputs are disabled during this write cycle, tWR, and the EEPROM
will not respond until the write is complete (see Figure 5-1 on page 9).
PAGE WRITE: The AT24C11 is capable of a 4-byte page write.
A page write is initiated the same 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 three more data words. The
EEPROM will respond with a zero after each data word received. The microcontroller must ter-
minate the page write sequence with a stop condition (see Figure 5-2 on page 9).
The data word address lower 2 bits are internally incremented following the receipt of each data
word. The higher five data word address bits are not incremented, retaining the memory page
row location. When the word address, internally generated, reaches the page boundary, the fol-
lowing byte is placed at the beginning of the same page. If more than four data words are
transmitted to the EEPROM, the data word address will “roll over” and previous data will be
overwritten. Access to 1 additional page is available upon request.
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.
5. 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 two read operations:
byte read and sequential read.
BYTE READ: A byte read is initiated with a start condition followed by a 7-bit data word address
and a high read bit. The AT24C11 will respond with an acknowledge and then serially output 8
data bits. The microcontroller does not respond with a zero but does generate a following stop
condition (see Figure 5-3 on page 9).
SEQUENTIAL READ: Sequential reads are initiated the same as a byte read. After the micro-
controller receives an 8-bit 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 an input zero but does generate a
following stop condition (see Figure 5-4 on page 9).
