Fairchild NM24C16UVMT8 16k-bit serial eeprom 2-wire bus interface Datasheet

NM24C16U/NM24C17U
16K-Bit Serial EEPROM
2-Wire Bus Interface
General Description
Functions
The NM24C16U/17U devices are 16K (16,384) bit serial interface
CMOS EEPROMs (Electrically Erasable Programmable ReadOnly Memory). These devices fully conform to the Standard I2C™
2-wire protocol which uses Clock (SCL) and Data I/O (SDA) pins
to synchronously clock data between the "master" (for example a
microprocessor) and the "slave" (the EEPROM device). In addition, the serial interface allows a minimal pin count packaging
designed to simplify PC board layout requirements and offers the
designer a variety of low voltage and low power options.
■ I2C™ compatible interface
■ 4,096 bits organized as 512 x 8
■ Extended 2.7V – 5.5V operating voltage
■ 100 KHz or 400 KHz operation
■ Self timed programming cycle (6ms typical)
■ "Programming complete" indicated by ACK polling
■ NM24C17U: Memory "Upper Block" Write Protect pin
Features
NM24C17U incorporates a hardware "Write Protect" feature, by
which, the upper half of the memory can be disabled against
programming by connecting the WP pin to VCC. This section of
memory then effectively becomes a ROM (Read-Only Memory)
and can no longer be programmed as long as WP pin is connected
to VCC.
■ The I2C™ interface allows the smallest I/O pincount of any
EEPROM interface
■ 16 byte page write mode to minimize total write time per byte
■ Typical 200µA active current (ICCA)
■ Typical 1µA standby current (ISB) for "L" devices and 0.1µA
standby current for "LZ" devices
Fairchild EEPROMs are designed and tested for applications requiring high endurance, high reliability and low power consumption for a
continuously reliable non-volatile solution for all markets.
■ Endurance: Up to 1,000,000 data changes
■ Data retention greater than 40 years

NM24C16U/NM24C17U – 16K-Bit Serial EEPROM 2-Wire Bus Interface
Bus Timing
Pin Descriptions
Background Information (IIC Bus)
Serial Clock (SCL)
As mentioned, the IIC bus allows synchronous bidirectional communication between Transmitter/Receiver using the SCL (clock)
and SDA (Data I/O) lines. All communication must be started with
a valid START condition, concluded with a STOP condition and
acknowledged by the Receiver with an ACKNOWLEDGE condition.
The SCL input is used to clock all data into and out of the device.
Serial Data (SDA)
SDA is a bidirectional pin used to transfer data into and out of the
device. It is an open drain output and may be wire–ORed with any
number of open drain or open collector outputs.
As shown below, the EEPROMs on the IIC bus may be configured
in any manner required, the total memory addressed can not
exceed 16K (16,384 bits). EEPROM memory address programming is controlled by 2 methods:
WP Write Protection (NM24C17U Only)
If tied to VCC, PROGRAM operations onto the upper half of the
memory will not be executed. READ operations are possible. If
tied to VSS, normal operation is enabled, READ/WRITE over the
entire memory is possible.
• All unused pins must be grounded (tied to VSS).
• Software addressing the required PAGE BLOCK within the
device memory array (as sent in the Slave Address string).
For devices with densities greater than 16K, a different protocol,
the Extended IIC protocol, is used. Refer to NM24C32U datasheet
(for example) for additional details.
This feature allows the user to assign the upper half of the memory
as ROM which can be protected against accidental programming.
When write is disabled, slave address and word address will be
acknowledged but data will not be acknowledged.
Addressing an EEPROM memory location involves sending a
command string with the following information:
[DEVICE TYPE]–[DEVICE ADDRESS]–[PAGE BLOCK ADDRESS]–[BYTE ADDRESS]
Device Operation
The NM24C16U/17U supports a bidirectional bus oriented protocol. The protocol defines any device that sends data onto the bus
as a transmitter and the receiving device as the receiver. The
device controlling the transfer is the master and the device that is
controlled is the slave. The master will always initiate data
transfers and provide the clock for both transmit and receive
operations. Therefore, the NM24C16U/17U will be considered a
slave in all applications.

Clock and Data Conventions
Data states on the SDA line can change only during SCL LOW.
SDA state changes during SCL HIGH are reserved for indicating
start and stop conditions. Refer to Figure 2 and Figure 3 on next
page.
Start Condition
SLAVE
Device being controlled
(EEPROMs are always considered
Slaves)
All commands are preceded by the start condition, which is a
HIGH to LOW transition of SDA when SCL is HIGH. The
NM24C16U/17U continuously monitors the SDA and SCL lines for
the start condition and will not respond to any command until this
condition has been met.
TRANSMITTER
Device currently SENDING data on
the bus (may be either a Master or
Slave).
Stop Condition
RECEIVER
All communications are terminated by a stop condition, which is a
LOW to HIGH transition of SDA when SCL is HIGH. The stop
condition is also used by the NM24C16U/17U to place the device
in the standby power mode.
Device currently RECEIVING data
on the bus (Master or Slave)
Write Cycle Timing
Acknowledge
Acknowledge is a hardware convention used to indicate successful data transfers. The transmitting device, either master or slave,
will release the bus after transmitting eight bits.
During the ninth clock cycle the receiver will pull the SDA line to
LOW to acknowledge that it received the eight bits of data. Refer
to Figure 4.

Write Cycle Timing (Figure 1)
Refer to the following table for Slave Addresses string details:
Device
The NM24C16U/17U device will always respond with an acknowledge after recognition of a start condition and its slave address. If
both the device and a write operation have been selected, the
NM24C16U/17U will respond with an acknowledge after the
receipt of each subsequent eight bit byte.

P: Refers to an internal PAGE BLOCK memory segment.
In the read mode the NM24C16U/17U slave will transmit eight bits
of data, release the SDA line and monitor the line for an acknowledge. If an acknowledge is detected and no stop condition is
generated by the master, the slave will continue to transmit data.
If an acknowledge is not detected, the slave will terminate further
data transmissions and await the stop condition to return to the
standby power mode.
All IIC EEPROMs use an internal protocol that defines a PAGE
BLOCK size of 2K bits (for Word addressess 0000 through 1111).
Therefore, address bits A0, A1, or A2 (if designated 'P') are used
to access a PAGE BLOCK in conjunction with the Word address
used to access any individual data byte (Word).
The last bit of the slave address defines whether a write or read
condition is requested by the master. A '1' indicates that a read
operation is to be executed, and a '0' initiates the write mode.
Device Addressing
Following a start condition the master must output the address of
the slave it is accessing. The most significant four bits of the slave
address are those of the device type identifier (see Figure 5). This
is fixed as 1010 for all EEPROM devices.
A simple review: After the NM24C16U/17U recognizes the start
condition, the devices interfaced to the IIC bus wait for a slave
address to be transmitted over the SDA line. If the transmitted
slave address matches an address of one of the devices, the
designated slave pulls the line LOW with an acknowledge signal
and awaits further transmissions.

NM24C16U/NM24C17U – 16K-Bit Serial EEPROM 2-Wire Bus Interface
Write Cycle Timing (Continued)
Once the stop condition is issued to indicate the end of the host’s
write operation the NM24C16U/17U initiates the internal write
cycle. ACK polling can be initiated immediately. This involves
issuing the start condition followed by the slave address for a write
operation. If the NM24C16U/17U is still busy with the write
operation no ACK will be returned. If the NM24C16U/17U has
completed the write operation an ACK will be returned and the
host can then proceed with the next read or write operation.
BYTE WRITE
For a write operation a second address field is required which is
a word address that is comprised of eight bits and provides access
to any one of the 256 bytes in the selected page of memory. Upon
receipt of the byte address the NM24C16U/17U responds with an
acknowledge and waits for the next eight bits of data, again,
responding with an acknowledge. The master then terminates the
transfer by generating a stop condition, at which time the
NM24C16U/17U begins the internal write cycle to the nonvolatile
memory. While the internal write cycle is in progress the
NM24C16U/17U inputs are disabled, and the device will not
respond to any requests from the master. Refer to Figure 6 for the
address, acknowledge and data transfer sequence.
Write Protection (NM24C17U Only)
Programming of the upper half of the memory will not take place
if the WP pin of the NM24C17U is connected to VCC. The
NM24C17U will accept slave and byte addresses; but if the
memory accessed is write protected by the WP pin, the NM24C17U
will not generate an acknowledge after the first byte of data has
been received, and thus the program cycle will not be started when
the stop condition is asserted.
PAGE WRITE
The NM24C16U/17U is capable of a sixteen byte page write
operation. It is initiated in the same manner as the byte write
operation; but instead of terminating the write cycle after the first
data byte is transferred, the master can transmit up to fifteen more
bytes. After the receipt of each byte, the NM24C16U/17U will
respond with an acknowledge.
After the receipt of each byte, the internal address counter
increments to the next address and the next SDA data is accepted.
If the master should transmit more than sixteen bytes prior to
generating the stop condition, the address counter will "roll over"
and the previously written data will be overwritten. As with the byte
write operation, all inputs are disabled until completion of the
internal write cycle. Refer to Figure 7 for the address, acknowledge, and data transfer sequence.

NM24C16U/NM24C17U – 16K-Bit Serial EEPROM 2-Wire Bus Interface
Acknowledge Polling
Write Operations
Read operations are initiated in the same manner as write
operations, with the exception that the R/W bit of the slave
address is set to a one. There are three basic read operations:
current address read, random read, and sequential read.
start condition and the slave address with the R/W bit set to one.
This will be followed by an acknowledge from the NM24C16U/17U
and then by the eight bit data. The master will not acknowledge the
transfer but does generate the stop condition, and therefore the
NM24C16U/17U discontinues transmission. Refer to Figure 9 for
the address, acknowledge and data transfer sequence.
Current Address Read
Sequential Read
Internally the NM24C16U/17U contains an address counter that
maintains the address of the last byte accessed, incremented by
one. Therefore, if the last access (either a read or write) was to
address n, the next read operation would access data from
address n + 1. Upon receipt of the slave address with R/W set to
one, the NM24C16U/17U issues an acknowledge and transmits
the eight bit byte. The master will not acknowledge the transfer
but does generate a stop condition, and therefore the NM24C16U/
17U discontinues transmission. Refer to Figure 8 for the sequence of address, acknowledge and data transfer.
Sequential reads can be initiated as either a current address read
or random access read. The first word is transmitted in the same
manner as the other read modes; however, the master now
responds with an acknowledge, indicating it requires additional
data. The NM24C16U/17U continues to output data for each
acknowledge received. The read operation is terminated by the
master not responding with an acknowledge or by generating a
stop condition.
The data output is sequential, with the data from address n
followed by the data from n + 1. The address counter for read
operations increments all word address bits, allowing the entire
memory contents to be serially read during one operation. After
the entire memory has been read, the counter "rolls over" and the
NM24C16U/17U continues to output data for each acknowledge
received. Refer to Figure 10 for the address, acknowledge, and
data transfer sequence.
Random Read
Random read operations allow the master to access any memory
location in a random manner. Prior to issuing the slave address
with the R/W bit set to one, the master must first perform a
“dummy” write operation. The master issues the start condition,
slave address and then the byte address it is to read. After the
byte address acknowledge, the master immediately reissues the
