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 must be hardwired for the AT24C02A. As many as eight 2K devices
may be addressed on a single bus system. (Device addressing is discussed in detail
under Device Addressing, page 8).

AT24C02A/04A
The AT24C04A uses the A2 and A1 inputs for hardwire addressing, and a total of four
4K devices may be addressed on a single bus system. The A0 pin is a no-connect.
WRITE PROTECT (WP): The AT24C02A/04A have a WP pin that provides hardware
data protection. The WP pin allows normal read/write operations when connected to
ground (GND). When the WP pin is connected to VCC, the write protection feature is
enabled and operates as shown.

Device Operation
CLOCK and DATA TRANSITIONS: The SDA pin is normally pulled high with an exter-
nal device. Data on the SDA pin may change only during SCL low time periods (see
Figure 2). Data changes during SCL high periods will indicate a start or stop condition as
defined below.
Figure 2. Data Validity
START CONDITION: A high-to-low transition of SDA with SCL high is a start condition
that must precede any other command (see Figure 3).
Figure 3. Start and Stop Definition
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 3).
ACKNOWLEDGE: All addresses and data words are serially transmitted to and from
the EEPROM in 8-bit words.. The EEPROM sends a “0” to acknowledge that it has
received each word. This happens during the ninth clock cycle.
STANDBY MODE: The AT24C02A/04A/08A/16A features a low-power standby mode
that is enabled: (a) upon power-up and (b) after the receipt of the Stop bit and the com-
pletion of any internal operations.
MEMORY RESET: After an interruption in protocol, power loss or system reset, any
two-wire part can be reset by following these steps:
1. Clock up to 9 cycles
2. Look for SDA high in each cycle while SCL is high
3. Create a start condition as SDA is high.

Device Addressing
The 2K and 4K EEPROM devices require an 8-bit device address word following a start
condition to enable the chip for a read or write operation, as shown in Figure 7.

The device address word consists of a mandatory “1”, “0” sequence for the first four
most significant bits as shown. This is common to all the EEPROM devices.
The next three bits are the A2, A1 and A0 device address bits for the 2K EEPROM.
These three bits must compare to their corresponding hardwired input pins.
The 4K EEPROM only uses the A2 and A1 device address bits with the third bit being a
memory page address bit. The two device address bits must compare to their corre-
sponding hardwired input pins. The A0 pin is no-connect.
The eighth bit of the device address is the read/write operation select bit. A read opera-
tion 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 “0”. If a compare is
not made, the chip will return to a standby state.
Write Operations
BYTE WRITE: A write operation requires an 8-bit data word address following the
device address word and acknowledgement. Upon receipt of this address, the EEPROM
will again respond with a “0” and then clock in the first 8-bit data word. Following receipt
of the 8-bit data word, the EEPROM will output a “0” 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 on page 8.

PAGE WRITE: The 2K EEPROM is capable of an 8-byte page write, and the 4K device
is capable of 16-byte page writes.

AT24C02A/04A
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 seven
(2K) or fifteen (4K) more data words. The EEPROM will respond with a “0” after each
data word received. The microcontroller must terminate the page write sequence with a
stop condition, see Figure 9.

The data word address lower three (2K) or four (4K) bits are internally incremented fol-
lowing 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, inter-
nally generated, reaches the page boundary, the following byte is placed at the
beginning of the same page. If more than eight (2K) or sixteen (4K) data words are
transmitted to the EEPROM, the data word address will “roll over” and previous 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 send-
ing 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 “0” allowing the read or write sequence to continue.

0976Q–SEEPR–8/05
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 “1”. 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 “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 cur-
rent page to the first byte of the same page.
Once the device address with the read/write select bit set to “1” 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 “0” but does generate a following
stop condition, see Figure 10.

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 “0” but does generate a following stop condition, see Figure 11.

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 sequen-

tial read will continue. The sequential read operation is terminated when the
microcontroller does not respond with a “0” but does generate a following stop condition,
see Figure 12.
