4. 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, and A0): The A2, A1, and A0 pins are device address inputs which are hard
wired for the AT24C01B/02B/04B/08B Automotive. As many as eight 1K/2K devices may be addressed on a
single bus system (device addressing is discussed in detail under the Device Addressing section). The
AT24C04B 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.
The AT24C08B only uses the A2 input for hardwire addressing and a total of two 8K devices may be addressed
on a single bus system. The A0 and A1 pins are no connect.
Write Protect (WP): The AT24C01B/02B/04B/08B has a Write Protect pin which 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 the following table.

6. 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.
Figure 6-1. Data Validity
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.

Acknowledge: All addresses and data words are serially transmitted to and from the EEPROM in 8-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 AT24C01B/02B/04B/08B Automotive features a low-power standby mode which is
enabled:
Upon power-up.
After the receipt of the Stop condition 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
protocol reset by following these steps:
1. Create a Start condition.
2. Clock nine cycles.
3. Create another start but followed by Stop condition as shown below.
The device is ready for the next communication after above steps have been completed.

7. Device Addressing
The 1K/2K/4K/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 “1”, “0” sequence for the first four most significant bits as
shown. This is common to all the Serial EEPROM devices.
The next three bits are the A2, A1, and A0 device address bits for the 1K/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 A0 bit being a memory address bit (P0).
The two device address bits must compare to their corresponding hardwired input pins. The A0 pin is no
connect.
The 8K EEPROM only uses the A2 device address bit with the next two bits (P9, P0) being for memory page
addressing. The A2 bit must compare to its corresponding hardwired 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.

8. 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.
Figure 8-1. Byte Write
Note: * = Don’t Care bit for 1K
Page Write: The 1K/2K EEPROM is capable of an 8-byte Page Write. The 4K/8K devices are capable of
16-byte Page Writes.
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 (1K/2K) or fifteen (4K/ 8K) 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 three (1K/2K) or four (4K/8K) 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 eight (1K/2K) or sixteen (4K/8K) data words are transmitted to
the EEPROM, the data word address will roll-over and previous data will be overwritten.
Figure 8-2. Page Write
Note: * = Don’t Care bit for 1K
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.

9. 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
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.
Figure 9-1. Current Address Read
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.

10. Power Recommendation
The device internal POR (Power-On Reset) threshold is just below the minimum operating voltage of the device.
Power shall rise monotonically from 0.0Vdc to full VCC in less than 1ms. Hold at full VCC for at least 100μs before
the first operation. Power shall drop from full VCC to 0.0Vdc in less than 1ms. Power dropping to a non-zero level
and then slowly going to zero is not recommended. Power shall remain off (0.0Vdc) for 0.5s minimum. Please
consult Atmel if your power conditions do not meet the above recommendations.
