Description
The Atmel® AT24C64B provides 65,536 bits of Serial Electrically Erasable and
Programmable Read-Only Memory (EEPROM) organized as 8,192 words of 8 bits
each. The device’s cascadable feature allows up to eight devices to share a
common 2-Wire bus. The device is optimized for use in many industrial and
commercial applications where low-power and low-voltage operation are
essential. The AT24C64B is available in space saving 8-lead JEDEC SOIC and
8-lead TSSOP packages and is accessed via a 2-Wire serial interface. In addition,
the entire family is available in 2.7V (2.7 to 5.5V) and 1.8V (1.8 to 5.5V) versions.

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 Addresses (A2, A1, A0): The A2, A1, and A0 pins are Device Address inputs which are hardwired or left
not connected for hardware compatibility with other AT24Cxxxx devices. When the pins are hardwired, as many
as eight 64Kb devices may be addressed on a single bus system (see Section 7., “Device Addressing”). If the
pins are left floating, the A2, A1, and A0 pins will be internally pulled down to GND if the capacitive coupling to the
circuit board VCC plane is <3pF. If coupling is >3pF, Atmel recommends connecting the address pins 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 upper quandrant (16Kb) of 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 <3pF. If coupling is >3pF, Atmel recommends connecting the pin to GND.

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. Data changes during SCL high periods will indicate a Start or
Stop condition as defined below.

SCL
Data Stable

Start Condition: A high-to-low transition of SDA with SCL high is a Start condition which must precede any
other command.
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.

Standby Mode: The AT24C64B features a low-power standby mode which is enabled:
Upon power-up,
After the receipt of the Stop bit, and
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:
1. Clock up to nine cycles,
2. Look for SDA high in each cycle while SCL is high,
3. Create a Start condition as SDA is high.
The device is ready for the next communication after the above steps have been completed.

Device Addressing
The 64Kb EEPROM requires an 8-bit device address word following a Start condition to enable the device for a
Read or Write operation. The device address word consists of a mandatory one, zero sequence for the first four
most significant bits as shown below. This is common to all 2-Wire EEPROM devices.
Figure 7-1.
Device Address
1
0
1
0
A2 A1 A0 R/W
LSB
MSB
The 64Kb uses the three Device Address bits A2, A1, and A0 to allow as many as eight devices on the same
bus. These bits must compare to their corresponding hardwired input pins. The A2, A1, and A0 pins use an
internal proprietary circuit that biases them to a Logic Low condition if the pins are allowed to float.
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 standby state.
Noise Protection: Special internal circuitry placed on the SDA and SCL pins prevent small noise spikes from
activating the device. A low-VCC detector resets the device to prevent data corruption in a noisy environment.
Data Security: The AT24C64B has a hardware data protection scheme which allows the user to write protect
the upper quadrant (16Kb) of memory when the WP pin is at VCC
.

Write Operations
Byte Write: A Write operation requires 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 and the
addressing device, i.e. 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.

Page Write: The 64K EEPROM is capable of 32-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 31 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.

The data word address’ lower five 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 32 data words are transmitted to the EEPROM, the data word address will roll-over
and the 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.

Read Operations
Read operations are initiated the same way as Write operations with the exception 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
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 device 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.

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.

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.
