No Connect: The NC pins are not bonded to a die pad. This pin can be
connected to GND or left floating.
Device Address Input: The A1 and A2 pins are used to select the
hardware device address and correspond to the sixth and fifth bit of the
I2C seven bit slave address. These pins can be directly connected to VCC
or GND, allowing up to four devices on the same bus.

The SDA pin must be pulled-high using an external pull-up resistor (not to
exceed 10K in value) and may be wire-ORed with any number of other
open-drain or open-collector pins from other devices on the same bus.
Serial Clock: The SCL pin is used to provide a clock to the device and to
control the flow of data to and from the device. Command and input data
present on the SDA pin is always latched in on the rising edge of SCL,
while output data on the SDA pin is clocked out on the falling edge of SCL.
SCL
The SCL pin must either be forced high when the serial bus is idle or
pulled-high using an external pull-up resistor.

Write Protect: Connecting the WP pin to GND will ensure normal write
operations.When the WP pin is connected to VCC, all write operations to
the memory are inhibited.

Note:
Device Power Supply: The VCC pin is used to supply the source voltage
to the device. Operations at invalid VCC voltages may produce spurious
results and should not be attempted.
VCC

If the A1, A2, or WP pins are not driven, they are internally pulled down to GND. In order to operate in a wide
variety of application environments, the pull-down mechanism is intentionally designed to be somewhat strong.
Once these pins are biased above the CMOS input buffer’s trip point (~0.5 x VCC), the pull-down mechanism
disengages. Atmel recommends connecting these pins to a known state whenever possible.

Device Operation and Communication
The AT24C04D operates as a slave device and utilizes a simple I2C-compatible 2-wire digital serial interface to
communicate with a host controller, commonly referred to as the bus Master. The Master initiates and controls
all Read and Write operations to the slave devices on the serial bus, and both the Master and the slave devices
can transmit and receive data on the bus.
The serial interface is comprised of just two signal lines: Serial Clock (SCL) and Serial Data (SDA). The SCL pin
is used to receive the clock signal from the Master, while the bidirectional SDA pin is used to receive command
and data information from the Master as well as to send data back to the Master. Data is always latched into the
AT24C04D on the rising edge of SCL and always output from the device on the falling edge of SCL. Both the
SCL and SDA pin incorporate integrated spike suppression filters and Schmitt Triggers to minimize the effects
of input spikes and bus noise.
All command and data information is transferred with the Most-Significant Bit (MSB) first. During bus
communication, one data bit is transmitted every clock cycle, and after eight bits (one byte) of data has been
transferred, the receiving device must respond with either an acknowledge (ACK) or a no-acknowledge (NACK)
response bit during a ninth clock cycle (ACK/NACK clock cycle) generated by the Master. Therefore, nine clock
cycles are required for every one byte of data transferred. There are no unused clock cycles during any Read or
Write operation, so there must not be any interruptions or breaks in the data stream during each data byte
transfer and ACK or NACK clock cycle.
During data transfers, data on the SDA pin must only change while SCL is low, and the data must remain stable
while SCL is high. If data on the SDA pin changes while SCL is high, then either a Start or a Stop condition will
occur. Start and Stop conditions are used to initiate and end all serial bus communication between the Master
and the slave devices. The number of data bytes transferred between a Start and a Stop condition is not limited
and is determined by the Master. In order for the serial bus to be idle, both the SCL and SDA pins must be in the
logic-high state at the same time.
3.1
Clock and Data Transition Requirements
The SDA pin is an open drain terminal and therefore must be pulled high with an external pull-up resistor. Data
on the SDA pin may change only during SCL low time periods. Data changes during SCL high periods will
indicate a Start or Stop condition as defined below.
3.2
Start and Stop Conditions
3.2.1
Start Condition
A Start condition occurs when there is a high-to-low transition on the SDA pin while the SCL pin is at a stable
Logic 1 state and will bring the device out of standby mode. The Master uses a Start condition to initiate any
data transfer sequence, therefore every command must begin with a Start condition. The device will
continuously monitor the SDA and SCL pins for a Start condition but will not respond unless one is detected.
Please refer to Figure 3-1 for more details.
3.2.2
Stop Condition
A Stop condition occurs when there is a low-to-high transition on the SDA pin while the SCL pin is stable in the
Logic 1 state. The Master can use the Stop condition to end a data transfer sequence with the AT24C04D which
will subsequently return to standby mode. The Master can also utilize a repeated Start condition instead of a
Stop condition to end the current data transfer if the Master will perform another operation. Please refer to
Figure 3-1 for more details.

Atmel-8896C-SEEPROM-AT24C04D-Datasheet_012015
3.3
Acknowledge and No-Acknowledge
After every byte of data is received, the receiving device must confirm to the Master that it has successfully
received the data byte by responding with what is known as an acknowledge (ACK). An ACK is accomplished
by the transmitting device first releasing the SDA line at the falling edge of the eighth clock cycle followed by the
receiving device responding with a Logic 0 during the entire high period of the ninth clock cycle.
When the AT24C04D is transmitting data to the Master, the Master can indicate that it is done receiving data
and wants to end the operation by sending a Logic 1 response to the AT24C04D instead of an ACK response
during the ninth clock cycle. This is known as a no-acknowledge (NACK) and is accomplished by the Master
sending a Logic 1 during the ninth clock cycle, at which point the AT24C04D will release the SDA line so the
Master can then generate a Stop condition.
The transmitting device, which can be the bus Master or the Serial EEPROM, must release the SDA line at the
falling edge of the eighth clock cycle to allow the receiving device to drive the SDA line to a Logic 0 to ACK the
previous 8-bit word. The receiving device must release the SDA line at the end of the ninth clock cycle to allow
the transmitter to continue sending new data. A timing diagram has been provided in Figure 3-1 to better
illustrate these requirements.

At the completion of an internal write cycle (see Section 5., “Write Operations”).
An unsuccessful match of the device type identifier or hardware address in the Device Address byte
occurs (see Section 4.1, “Device Addressing”).
The bus Master does not ACK the receipt of data read out from the device; instead it sends a NACK
response. (see Section 6., “Read Operations”).

Memory Organization
The AT24C04D is internally organized as 32 pages of 16 bytes each.
4.1
Device Addressing
Accessing the device requires an 8-bit Device Address word following a Start condition to enable the device for
a read or write operation. Since multiple slave devices can reside on the serial bus each slave device must have
its own unique address so that the Master can access each device independently.
The most significant four bits of the Device Address word is referred to as the device type identifier. The device
type identifier ‘1010’ (Ah) is required in bits seven through four of the Device Address byte (see Table 4-1).
Following the 4-bit device type identifier are the hardware slave address bits, A2 and A1. These bits can be used
to expand the address space by allowing up to four 4-Kbit Serial EEPROM devices on the same bus. The A2
and A1 values must correlate with the voltage level on the corresponding hardwired input pins A2 and A1.
The A2 and A1 pins use an internal proprietary circuit that automatically biases it to a Logic 0 state if the pin is
allowed to float. In order to operate in a wide variety of application environments, the pull-down mechanism is
intentionally designed to be somewhat strong. Once these pins are biased above the CMOS input buffer’s trip
point (~0.5 x VCC), the pull-down mechanism disengages. Atmel recommends connecting the A2 and A1 pins to
a known state whenever possible.
When using the SOT23 package, the A2 and A1 pins are not accessible and are left floating. The previously
mentioned automatic pull-down circuit will set these pins to a Logic 0 state. As a result, to properly communicate
with the device in the SOT23 packages, the A2 and A1 software bits must always be set to Logic 0 for any
operation.
Following the A2 and A1 hardware slave address bits is bit A8 (bit 1 of the Device Address byte), which is the
most significant bit of the memory array word address. Please refer to Table 4-1 to review these bit positions.
The eighth bit (bit 0) of the Device Address byte 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 the successful comparison of the Device Address byte, the EEPROM will return an ACK. If a valid
comparison is not made, the device will NACK and return to a standby state.

For all operations except the Current Address Read, a Word Address byte must be transmitted to the device
immediately following the Device Address byte. The Word Address byte consists of the remaining eight bits of
the 9-bit memory array word address, and is used to specify which byte location in the EEPROM to start reading
or writing. Please refer to Table 4-2 to review these bit positions.

Write Operations
All Write operations for the AT24C04D begin with the Master sending a Start condition, followed by a Device
Address byte with the R/W bit set to ‘0’, and then by the Word Address byte. The data value(s) to be written to
the device immediately follow the Word Address byte.
5.1
Byte Write
The AT24C04D supports the writing of single 8-bit bytes. Selecting a data word in the AT24C04D requires a
9-bit word address.
Upon receipt of the proper Device Address and Word Address bytes, the EEPROM will send an Acknowledge.
The device will then be ready to receive the first 8-bit data word. Following receipt of the 8-bit data word, the
EEPROM will respond with an Acknowledge. The addressing device, such as a bus Master, must then terminate
the Write operation with a Stop condition. At that time the EEPROM will enter an internally self-timed write cycle,
which will be completed within tWR, while the data word is being programmed into the nonvolatile EEPROM. All
inputs are disabled during this write cycle, and the EEPROM will not respond until the Write is complete.

Page Write
A Page Write operation allows up to 16 bytes to be written in the same write cycle, provided all bytes are in the
same row of the memory array (where address bits A8 through A4 are the same). Partial Page Writes of less
than 16 bytes are also allowed.
A Page Write is initiated the same way as a Byte Write, but the bus Master 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 bus
Master can transmit up to fifteen additional data words. The EEPROM will respond with an ACK after each data
word is received. Once all data to be written has been sent to the device, the bus Master must issue a Stop
condition (see Figure 5-2) at which time the internally self-timed write cycle will begin.
The lower four bits of the word address are internally incremented following the receipt of each data word. The
higher order address bits are not incremented and retain the memory page row location. Page Write operations
are limited to writing bytes within a single physical page, regardless of the number of bytes actually being
written. When the incremented word address reaches the page boundary, the address counter will “roll over” to
the beginning of the same page. Nevertheless, creating a roll over event should be avoided as previously
loaded data in the page could become unintentionally altered.

Acknowledge Polling
An Acknowledge Polling routine can be implemented to optimize time sensitive applications that would prefer
not to wait the fixed maximum write cycle time (tWR). This method allows the application to know immediately
when the Serial EEPROM write cycle has completed, so a subsequent operation can be started.
Once the internally self-timed write cycle has started, an Acknowledge Polling routine can be initiated. This
involves repeatedly sending a Start condition followed by a valid Device Address byte with the R/W bit set at
Logic 0. The device will not respond with an ACK while the write cycle is ongoing. Once the internal write cycle
has completed, the EEPROM will respond with an ACK, allowing a new Read or Write operation to be
immediately initiated. A flow chart has been included below in Figure 5-3 to better illustrate this technique.

Write Cycle Timing
The length of the self-timed write cycle, or tWR, is defined as the amount of time from the Stop condition that
begins the internal Write operation, to the Start condition of the first Device Address byte sent to the AT24C04D
that it subsequently responds to with an ACK. Figure 5-4 has been included to show this measurement. During
the internally self-timed write cycle any attempts to read from or write to the memory array will not be processed.

Write Protection
The AT24C04D utilizes a hardware data protection scheme that allows the user to write protect the entire
memory contents when the WP pin is at VCC (or a valid VIH). No write protection will be set if the WP pin is at
GND or left floating.
Table 5-1.

None — Write Protection Not Enabled
The status of the WP pin is sampled at the Stop condition for every Byte Write or Page Write command prior to
the start of an internally self-timed Write operation. Changing the WP pin state after the Stop condition has been
sent will not alter or interrupt the execution of the write cycle. The WP pin state must be valid with respect to the
associated setup (tSU.WP) and hold (tHD.WP) timing as shown in the Figure 5-5 below. The WP setup time is the
amount of time that the WP state must be stable before the Stop condition is issued. The WP hold time is the
amount of time after the Stop condition that the WP state must remain stable.
If an attempt is made to write to the device while the WP pin has been asserted, the device will acknowledge the
Device Address, Word Address, and Data bytes but no write cycle will occur when the Stop condition is issued,
and the device will immediately be ready to accept a new Read or Write command.

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 must be a Logic 1. There are three Read operations:



6.1
Current Address Read
Random Address Read
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 VCC is maintained to
the part. The address “roll over” during read is from the last byte of the last page to the first byte of the first page
of the memory.
A Current Address Read operation will output data according to the location of the internal data word address
counter. This is initiated with a Start condition, followed by a valid Device Address byte with the R/W bit set to
Logic 1. The device will ACK this sequence and the current address data word is serially clocked out on the
SDA line. All types of Read operations will be terminated if the bus Master does not respond with an ACK (it
NACKs) during the ninth clock cycle, which will force the device into standby mode. After the NACK response,
the Master may send a Stop condition to complete the protocol, or it can send a Start condition to begin the next
sequence.

Random Read
A Random Read begins in the same way as a Byte Write operation does to load in a new data word address.
This is known as a “dummy write” sequence; however, the Stop condition of the Byte Write must be omitted to
prevent the part from entering an internal write cycle. Once the Device Address and Word Address are clocked
in and acknowledged by the EEPROM, the bus Master must generate another Start condition. The bus Master
now initiates a Current Address Read by sending a Start condition, followed by a valid Device Address byte with
the R/W bit set to Logic 1. The EEPROM will ACK the Device Address and serially clock out the data word on
the SDA line. All types of Read operations will be terminated if the bus Master does not respond with an ACK (it
NACKs) during the ninth clock cycle, which will force the device into standby mode. After the NACK response,
the Master may send a Stop condition to complete the protocol, or it can send a Start condition to begin the next
sequence.

Sequential Read
Sequential Reads are initiated by either a Current Address Read or a Random Read. After the bus Master
receives a data word, it responds with an acknowledge. As long as the EEPROM receives an ACK, it will
continue to increment the word address and serially clock out sequential data words. When the maximum
memory address is reached, the data word address will “roll over” and the sequential read will continue from the
beginning of the memory array. All types of Read operations will be terminated if the bus Master does not
respond with an ACK (it NACKs) during the ninth clock cycle, which will force the device into standby mode.
After the NACK response, the Master may send a Stop condition to complete the protocol, or it can send a Start
condition to begin the next sequence.

8.5
Power-Up Requirements and Reset Behavior
During a power-up sequence the VCC supplied to the AT24C04D should monotonically rise from GND to the
minimum VCC level as specified in Section 8.2, with a slew rate no greater than 1V/μs.
8.5.1
Device Reset
To prevent inadvertent write operations or other spurious events from happening during a power-up sequence,
the AT24C04D includes a power-on-reset (POR) circuit. Upon power-up, the device will not respond to any
commands until the VCC level crosses the internal voltage threshold (VPOR) that brings the device out of reset
and into standby mode.
The system designer must ensure that instructions are not sent to the device until the VCC supply has reached a
stable value greater than the minimum VCC level. Additionally, once the VCC has surpassed the minimum VCC
level, the bus Master must wait at least tPUP before sending the first command to the device. See Table 8-4 for
the values associated with these power-up parameters.

These parameters are characterized but they are not 100% tested in production.
If an event occurs in the system where the VCC level supplied to the AT24C04D drops below the maximum VPOR
level specified, it is recommended that a full power cycle sequence be performed by first driving the VCC pin to
GND, waiting at least the minimum tPOFF time, and then performing a new power-up sequence in compliance
with the requirements defined in this section.
