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 bi-directional 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, A0): I2C signals A0, A1, and A2 (device package pins 1, 2, and 3) are no
connects. AT24C16C does not use the device address pins, which limits the number of devices on a single bus
to one.
Write Protect (WP): AT24C16C 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 WP pin is
connected to VCC, the write protection feature is enabled and operates as shown in the following table. If WP is
left floating, it 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.

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 condition will place the EEPROM in a standby power mode.

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 device that
it subsequently responds to with an ACK.
AT24C16C Automotive [DATASHEET]

Device Addressing
The 16K EEPROM 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 one, zero sequence for the first four most significant bits as
shown. This is common to all the Serial EEPROM devices.
The next three bits are used for memory page addressing. These page addressing bits on the 16K devices
should be considered the most significant bits of the data Word Address which follows.
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.
If the device address meets the requirements listed above, the device will acknowledge with a zero by pulling
the SDA signal low. If the comparison is not made, the device will return to a standby state and the SDA signal
will float high.

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.

Page Write: The EEPROM is 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 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.
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 sixteen data words are transmitted to the EEPROM, the data Word Address will rollover 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.

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
ACK (no ACK) 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 an ACK (no ACK) but
does generate a 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 send an
ACK (no ACK), but does generate the Stop condition.

Power Recommendation
The device internal POR (Power-On Reset) threshold is just below the minimum device operating voltage.
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 shall remain off (0.0Vdc) for
0.03ms minimum. Power dropping to a non-zero level and then slowly going to zero is not recommended, but if
unavoidable the VCC level supplied to the part must remain below 0.5V for at least 0.1ms to ensure a proper
reset.
Please consult Atmel if your power conditions do not meet the above recommendations.
