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: A total of one device
may be addressed on a single bus system.
WRITE PROTECT (WP): The FM24C16D
has a
Write Protect pin that provides hardware data
protection. The WP pin allows normal write operations
when connected to ground (GND). When the Write
Protect pin is connected 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, FMSH recommends
connecting the WP to GND. Switching WP to VCC
prior to a write operation creates a software write
protected function.

Security Sector ： The FM24C16D offers 16-byte Security Sectors which can be written and (later)
permanently locked in Read-only mode. These registers may be used by the system manufacturers to store
security and other important information separately from the main memory array.
Unique ID: The FM24C16D utilizes a separate memory block containing a factory programmed 128-bit
unique ID. Access to this memory location is obtained by beginning the device address word with a „1011‟(Bh)
sequence.

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 Figure 4). 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 Figure 5).
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 Figure 5).
ACKNOWLEDGE: All address 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 FM24C16D
features a
low-power standby mode which is enabled: (a)
upon power-up and (b) after the receipt of the stop
bit and the completion of any internal operations.
Memory RESET: After an interruption in protocol,
power loss or system reset, any 2-wire part can be
reset in following these steps:
1. Clock up to 9 Cycles,
2. Look for SDA high in each cycle while SCL is
high and then,
3. Create a start condition as SDA is high.

Device Addressing
Data Memory Access:
The FM24C16D device requires an 8-bit device
address word following a start condition to enable
the chip for a read or write operation (refer to Table
1~2).
The device address word consists of a mandatory
„1010‟ sequence for the first four most significant bits
and the fifth to seventh bits are memory page
address bits as shown in Table 1~2.
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.
Unique ID Access: The FM24C16D utilizes a
separate memory block containing a factory
programmed 128-bit unique ID. Access to this
memory location is obtained by beginning the device
address word with a „1011‟(Bh) sequence (refer to
Table 1~2). The behavior of the next three bits
remains the same as during a standard memory
addressing sequence.
The eighth bit of the device address needs be set to
FM24C16D 2-Wire Serial EEPROM
a one to read the Serial Number. Writing or altering
the 128-bit unique ID is not possible.
For more details on accessing this special feature,
See Read Operations on page 14.
Security Sector Access: The FM24C16D offers
16-byte Security Sector which can be written and
(later) permanently locked in Read-only mode.
Access to this memory location is obtained by
beginning the device address word with a „1011‟(Bh)
sequence (refer to Table 1~2). The behavior of the next
three bits remains the same as during a standard
memory addressing sequence.
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.
For more details on accessing this special feature, See
Write Operations and Read Operations on page 14.
NOISE PROTECTION: Special internal circuitry
placed on the SDA and SCL pins prevent small noise
spikes from activating the device.
DATA SECURITY: The Device has a hardware data
protection scheme that allows the user to write protect
the entire memory when the WP pin is at VCC.

Write Operations
BYTE WRITE: A write operation requires two 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 (refer to
Figure 7 on page 15).
PAGE WRITE: The 16K EEPROM is capable of
16-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 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 (refer to Figure 8 on page 15).
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 “roll over” and previous data will be
overwritten.
FM24C16D 2-Wire Serial EEPROM
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.
WRITE SECURITY SECTOR: Write the Security
Sector is similar to the page write but requires use
of device address, and the special word address
seen in Table 1~2 on page 12. Address bits A
which must be equal to „00b‟. Lower address bits
A define the byte address inside the Security
Sector (refer to Figure 12 on page 16).And other
address bits are don‟t care.
If the Security Sector is locked, the data bytes
transferred during the Write Security Sector
operation are not acknowledged (NoAck).
LOCK SECURITY SECTOR: Lock the Security
Sector is similar to the byte write but requires use
of device address, and special word address seen
in Table 1 on page 12. The word address bits
A must be „x1b‟, all other word address bits
are don‟t care. The data byte must be equal to the
binary value xxxx xx1x, where x is don't care (see
Figure 14 on page 17.
If the Security Sector is locked, the data bytes
transferred during the Lock Security Sector
operation are not acknowledged (NoAck).
Ver1.4

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.
don‟t care. If the application desires to read the
first byte of the UID, the lower address bits A
would need to be „0000b‟.
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.
When the end of the 128-bit UID number is
reached (16 bytes of data), the data word address
will roll-over back to the beginning of the 128-bit
UID number. The Unique ID Read operation is
terminated when the microcontroller does not
respond with a zero (ACK) and instead issues a
Stop condition (see Figure 16 on page 18).
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 9 on page 15).
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 10 on page 16).
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 11 on page 16)
UNIQUE ID READ: Reading the serial number is
similar to the sequential read but requires use of
the device address, a dummy write, and the use of
specific word address seen in Table 1~2 on page
12. Address bits A which must be equal to
„10b‟. Lower address bits A define the byte
address inside the UID..And other address bits are
FM24C16D 2-Wire Serial EEPROM
READ SECURITY SECTOR：Read the Security
Sector is similar to the random read but requires
use of device address, a dummy write, and the
use of specific word address seen in Table 1~2 on
page 12. The higher address bits are don‟t care
except for address bits A， which must be
equal to „00b‟. The lower address bits A
define the byte address inside the Security Sector.
The internal byte address is automatically
incremented to the next byte address after each
byte of data is clocked out. When the last byte (0Fh)
is reached, it will roll over to 00h, the first byte of the
Security Sector, and continue to increment. (see
Figure 13 on page 17).
READ LOCK STATUS：There are two ways to
check the lock status of the Security Sector.
1. The first way is initiated by a Security Sector
Write, the EEPROM will acknowledge if the
Security Sector is unlocked, while it will not
acknowledge if the Security Sector is locked.
Once the acknowledge bit is read, it is
recommended to generate a Start condition
followed by a Stop condition, so that:
Start: the truncated command is not executed
because the Start condition resets the device
internal logic
Stop: the device is then set back into Standby
mode by the Stop condition.
2. The second way is initiated by a Lock Status
Read. Lock Status Read is similar to the random
read but requires use of device address seen in
Table 1 on page 12, a dummy write, and the use
of specific word address. The address bits A
must be „x1b‟, all other address bits are Don't
Care. The Lock bit is the BIT1 of the byte read on
SDA. It is at “1” when the lock is active and at “0”
when the lock is not active. The same data is
shifted out repeatedly until the microcontroller
does not respond with a zero but does generate a
following stop condition (see Figure 15 on page
18).
