3. 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 and A1): The AT24C04C uses the A2 and A1 inputs for hard wire addressing allowing a
total of four 4K devices to be addressed on a single bus system. Pin 1 is a no connect and can be connected to ground
(see Section 6. “Device Addressing” on page 10). The AT24C08C only uses the A2 input for hardware addressing and a
total of two 8K devices may be addressed on a single bus system. The A0 and A1 pins are no connects and can be
connected to ground (see Section 6. “Device Addressing” on page 10).
Write Protect (WP): AT24C04C/08C has a Write Protect pin that provides hardware data protection. The Write Protect
pin allows normal read/write operations when connected to Ground (GND). When the Write Protect pin is connected to
VCC, the write protection feature is enabled and operates as shown in Table 3-1.

5. 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 5-4 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 5-5 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 5-5 on page 9).
Acknowledge: All addresses and data words are serially transmitted to and from the EEPROM in eight 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 Atmel AT24C04/08C features a low-power standby mode which is enabled:
 Upon power-up
 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.
The device is ready for next communication after above steps have been completed.

6. Device Addressing
Standard EEPROM Access: The 4K and 8K 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” (0xA)
sequence for the first four Most Significant Bits (MSB) as shown in Figure 8-1 on page 11. This is common to all the
EEPROM devices.
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 corresponding hard-wired input pins. The A0 pin is no connect.
The 8K EEPROM only uses the A2 device address bit with the next two bits being for memory page addressing. The A2
address bit must compare to its corresponding hard-wired input pin. The A1 and A0 pins are no connect.
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 chip will return to
a standby state.
For the SOT23 package offering, the 4K EEPROM software A2 and A1 bits in the device address word must be set to
zero to properly communicate. The 8K EEPROM software A2 bit in the device address word must be set to zero to
properly communicate.

7. Write Operations
Byte Write: A 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 8-2 on page 11).
Page Write: The 4K and 8K EEPROM devices are capable of a 16-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 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 8-3 on page 12).
The data word address lower four 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
16 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 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.

Atmel-8787D-SEEPROM-AT24C04C,08C-Datasheet_042013
8. 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 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 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 input zero but does
generate a following stop condition (see Figure 8-4 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 8-5 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 8-6 on page 12).
