Description
32K (4096 x 8)
The Atmel® AT24C32D/64D provides 32,768-/65,536-bits of serial electrically eras-
able and programmable read only memory (EEPROM) organized as 4096/8192 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 commer-
cial applications where low power and low voltage operation are essential. The
AT24C32D/64D is available in space saving 8-lead JEDEC SOIC, 8-lead TSSOP, 8-
lead UDFN, 8-lead XDFN, 5-lead SOT23 and 8-ball VFBGA and is accessed via a 2-
wire serial interface. In addition, the entire family operates from 1.7V to 5.5V.

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 that are hard wired or left
not connected for hardware compatibility with other Atmel® AT24CXX devices. When the pins are hardwired, as
many as eight 32K/64K devices may be addressed on a single bus system (device addressing is discussed in
detail under the Device Addressing section). 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 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 (refer to “Data Validity” diagram). 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 (refer to “Start and Stop Definition” diagram).
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 (refer to “Start and Stop Definition” diagram).
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 Atmel® AT24C32D/64D 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.
SOFTWARE RESET: After an interruption in protocol, power loss or system reset, and 2-wire part can be protocol
reset by following these steps:
• Create a start bit condition
• Clock nine cycles
• 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.

Device Addressing
The 32K/64K 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 10 ). 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 2-wire EEPROM devices.
The 32K/64K uses the three device address bits A2, A1, 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.
DATA SECURITY: The Atmel® AT24C32D/64D 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: 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, 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 7-2 on page 10).
PAGE WRITE: The 32K/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 (see Figure 7-3 on
page 11).
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
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.

8717B–SEEPR–6/10
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 “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 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 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 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 11).
