2. 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 bi-directional for serial data transfer. This pin is opendrain driven and may be wire-ORed with any number of other open-drain or open-collector
devices.
DEVICE/ADDRESSES (A1/A2): The A1, A2 pin is a device address input that can be hardwired
or left not connected for hardware compatibility with other AT24Cxx devices. When the A1, A2
pins are hardwired, as many as four 1024K devices may be addressed on a single bus system
(device addressing is discussed in detail under the Device Addressing section). If the A1/A2 pins
are left floating, the A1/A2 pin will be internally pulled down to GND if the capacitive coupling to
the circuit board VCC plane is <3 pF. If coupling is >3 pF, Atmel recommends connecting the
A1/A2 pin to GND.
WRITE PROTECT (WP): The write protect input, when connected to GND, allows normal write
operations. When WP is connected high to VCC, all write operations to the memory are inhibited.
If the pin is left floating, the WP pin will be internally pulled down to GND if the capacitive coupling to the circuit board VCC plane is <3 pF. If coupling is >3 pF, Atmel recommends connecting
the pin to GND. Switching WP to VCC prior to a write operation creates a software write-protect
function.

4. 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 4-4 on
page 7). Data changes during SCL high periods will indicate a start or stop condition as defined
below.
5
5194F–SEEPR–1/08
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 8).
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 8).
ACKNOWLEDGE: All addresses and data words are serially transmitted to and from the
EEPROM in 8-bit words. The EEPROM sends a zero during the ninth clock cycle to acknowledge that it has received each word.
STANDBY MODE: The AT24C1024B 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.
SOFTWARE RESET: After an interruption in protocol, power loss or system reset, any 2-wire
part can be protocol reset by following these steps: (a) Create a start bit condition, (b) clock 9
cycles, (c) create another start bit followed by stop bit condition as shown below. The device is
ready for next communication after above steps have been completed.

5. Device Addressing
The 1024K EEPROM requires an 8-bit device address word following a start condition to enable
the chip for a read or write operation (see Figure 7-1 on page 11). The device address word consists of a mandatory one, zero sequence for the first four most significant bits as shown. This is
common to all two-wire EEPROM devices.
The 1024K uses the two device address bit, A1, A2, to allow up to four devices on the same bus.
These A1, A2 bits must compare to the corresponding hardwired input pins. The A1, A2 pin uses
an internal proprietary circuit that biases it to a logic low condition if the pin is allowed to float.
The seventh bit (P0) of the device address is a memory page address bit. This memory page
address bit is the most significant bit of the data word address that follows. 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.

5194F–SEEPR–1/08
AT24C1024B
DATA SECURITY: The AT24C1024B has a hardware data protection scheme that allows the
user to write-protect the entire memory when the WP pin is at VCC.
6. Write Operations
BYTE WRITE: To select a data word in the 1024K memory requires a 17-bit word address. The
word address field consists of the P0 bit of the device address, then the most significant word
address followed by the least significant word address (see Figure 7-2 on page 11)
A write operation requires the P0 bit and two 8-bit data word addresses 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. The addressing device, such as a microcontroller, then
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 7-2 on page
11).
PAGE WRITE: The 1024K EEPROM is capable of 256-byte page writes.
A page write is initiated 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 255 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 7-3 on page 11).
The data word address lower 8 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 word address, internally generated, reaches the page boundary, the following byte is placed at the beginning of the same page. If more than 256 data words are
transmitted to the EEPROM, the data word address will “roll over” and previous data will be
overwritten. The address “rollover” during write is from the last byte of the current page to the
first byte of the same page.
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. 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 read operations:
current address read, random address read and 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 the chip power is maintained. The address “rollover”
during read is from the last byte of the last memory page, to the first byte of the first page.
9
5194F–SEEPR–1/08
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 input zero but does generate a following stop condition (see Figure 7-4 on
page 11).
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 7-5 on page 12).
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 7-6 on page 12).
