Power-On Reset (POR)  
Data transfer may be initiated only when the bus is not  
busy (see A.C. Characteristics).  
The N24S128 incorporates Power-On Reset (POR)  
circuitry which protects the device against powering up in  
the wrong state.  
The N24S128 will power up into Standby mode after V  
exceeds the POR trigger level and will power down into  
During data transfer, the SDA line must remain stable  
while the SCL line is HIGH. An SDA transition while SCL  
is HIGH will be interpreted as a START or STOP condition  
(Figure 3). The START condition precedes all commands. It  
consists of a HIGH to LOW transition on SDA while SCL  
is HIGH. The START acts as a ‘wake-up’ call to all  
receivers. Absent a START, a Slave will not respond to  
commands. The STOP condition completes all commands.  
It consists of a LOW to HIGH transition on SDA while SCL  
is HIGH.

This bi-directional POR feature protects the device against  
‘brown-out’ failure following a temporary loss of power.  
Pin Description  
SCL: The Serial Clock input pin accepts the Serial  
Clock generated by the Master.  
Device Addressing  
SDA: The Serial Data I/O pin receives input data and  
transmits data stored in EEPROM. In transmit mode,  
this pin is open drain. Data is acquired on the positive  
edge, and is delivered on the negative edge of SCL.  
The Master initiates data transfer by creating a START  
condition on the bus. The Master then broadcasts an 8-bit  
serial Slave address. The first 4 bits of the Slave address are  
set to 1010, for normal Read/Write operations, and to 1011  
for special Read/Write operations (Figure 4). The next 3 bits  
must match the A2, A1, A0 bits in the Device Configuration  
Register. The last bit, R/W, specifies whether a Read (1) or  
Write (0) operation is to be performed.  
Functional Description  
The N24S128 supports the Inter-Integrated Circuit (I C)  
2
Bus data transmission protocol, which defines a device that  
sends data to the bus as a transmitter and a device receiving  
data as a receiver. Data flow is controlled by a Master device,  
which generates the serial clock and all START and STOP  
conditions. The N24S128 acts as a Slave device. Master and  
Slave alternate as either transmitter or receiver. Up to 8  
devices may be connected to the bus as determined by the  
The factory default for the A2, A1, A0 bits is 0.  
Acknowledge  
After processing the Slave address, the Slave responds  
with an acknowledge (ACK) by pulling down the SDA line  
th  
during the 9 clock cycle (Figure 5). The Slave will also

The I C bus consists of two ‘wires’, SCL and SDA. The  
long as the Master acknowledges the data, the Slave will  
continue transmitting. The Master terminates the session by  
not acknowledging the last data byte (NoACK) and by  
issuing a STOP condition. Bus timing is illustrated in  
Figure 6.  
two wires are connected to the V supply via pull-up

resistors. Master and Slave devices connect to the 2-wire bus  
via their respective SCL and SDA pins. The transmitting  
device pulls down the SDA line to ‘transmit’ a ‘0’ and  
releases it to ‘transmit’ a ‘1’.

N24S128  
Write Operations  
Configuration register. The second byte consists of xxxx  
x00x, where x is don’t care. The third byte indicates the  
address within the Secure Data Page. Since the page is  
64-bytes wide, the first 2 bits of the address are don’t care.  
The remainder of the instruction is identical to a normal  
Page Write.  
Byte Write  
In Byte Write mode the Master sends a START, followed  
by Slave address, two byte address (Table 8) and data to be  
written (Figure 7). The Slave, N24S128 acknowledges all  
4 bytes, and the Master then follows up with a STOP, which  
in turn starts the internal Write operation (Figure 8). During  
Secure Data Page Lock  
the internal Write cycle (t ), the N24S128 will not  
acknowledge any Read or Write request from the Master.  
The Secure Data Page Lock instruction is similar to a Byte  
Write instruction. To lock the Secure Data Page against  
future changes, the user must address the device with the  
header 1011 followed by the A2 A1 A0 bits that match the  
bits in the Device Configuration register. The second byte  
consists of xxxx x10x, where x is don’t care. The third byte  
is don’t care.  
The data byte following the address bytes must be all 1s  
(FFh). After this instruction is sent, the user will be able to  
read, but not to write the content of the Secure Data Page.  
Any write instructions to the Secure Data Page will return  
No ACK from the device.  
WR  
Page Write  
The N24S128 contains 16,384 bytes of data, arranged in  
256 pages of 64 bytes each. A two byte address word  
(Table 8), following the Slave address, points to the first byte  
to be written into the memory array. The most significant 8  
bits from the address active bits (a13 to a6) identify the page  
and the last 6 bits (a5 to a0) identify the byte within the page.  
Up to 64 bytes can be written in one Write cycle (Figure 9).  
The internal byte address counter is automatically  
incremented after each data byte is loaded. If the Master  
transmits more than 64 data bytes, then earlier bytes will be  
overwritten by later bytes in a ‘wrap-around’ fashion (within  
the selected page). The internal Write cycle starts  
immediately following the STOP.  
Device Configuration Register Write  
The Device Configuration Register Write instruction is  
similar to a Byte Write instruction. The user must address the  
device with the header 1011b followed by the A2 A1 A0 bits  
that match the bits in the Device Configuration register. The  
second byte consists of xxxx x11x, where x is don’t care. The  
third byte is don’t care.  
The data byte following the address will be written into the  
Device Configuration Register (see Table 9 for the position  
of each bit.) The A2, A1, A0 bits determine the Device  
Address.  
The SWP bit is the Software Write Protection bit. When  
SWP is set to 1, the memory array, the Secure Data Page and  
the Device Configuration Register are protected against  
write operations. The A2, A1, A0 bits cannot be overwritten  
during a Device Configuration Register write operation if  
SWP is set to 1. The SWP bit alone can be changed to 0.  
The Device Configuration Register Write instruction does  
not support acknowledge polling.  
Acknowledge Polling  
The ready/busy status of the N24S128 can be ascertained  
by sending Read or Write requests immediately following  
the STOP condition that initiated the internal Write cycle. As  
long as internal Write is in progress, the N24S128 will not  
acknowledge the Slave address.  
The Device Configuration Register Write instruction does  
not support acknowledge polling. Following this  
instruction, the master must wait t  
a new instruction.

Secure Data Page Write  
The Secure Data Page Write instruction is similar to a

user must address the device with the header 1011 followed

N24S128  
Read Operations  
the device header and two address bytes as for a Device  
Configuration Register Write instruction. This dummy write  
instruction is followed by an Immediate Read with the  
device header 1011b, and the device will shift back the  
content of the Device Configuration Register. Don’t care  
bits are read as 1s.  
If the master acknowledges the data byte, requesting more  
data, the device will continue to return the content of the  
Device Configuration Register until the Master responds  
with a NoACK.  
Immediate Read  
Upon receiving a Slave address with the R/W bit set to ‘1’,  
the N24S128 will interpret this as a request for data residing  
at the current byte address in memory. The N24S128 will  
acknowledge the Slave address, will immediately shift out  
the data residing at the current address, and will then wait for  
the Master to respond. If the Master does not acknowledge  
the data (NoACK) and then follows up with a STOP  
condition (Figure 10), the N24S128 returns to Standby  
mode.  
Unique ID Number Read  
The Unique ID Number Read instruction is similar to  
a Sequential Read instruction. The user must send the device  
header starting with 1011b followed by the A2 A1 A0 bits  
that match the bits in the Device Configuration register. As  
specified in Table 8, the second byte consists of xxxx x01x  
and the third byte of xxxx 0000, where x is don’t care. This  
dummy write instruction is followed by an Immediate Read  
with the device header 1011b, and the device will shift back  
the Unique ID byte by byte. The Unique ID is 16 bytes  
(128 bits) long. After the last byte of the Unique ID has been  
shifted, if the master acknowledges (requesting more data),  
the device will wrap-around and start returning the Unique  
ID from the beginning.  
Selective Read  
To read data residing at a specific location, the internal  
address counter must first be initialized as described under  
Byte Write. If rather than following up the two address bytes  
with data, the Master instead follows up with an Immediate  
Read sequence, then the N24S128 will use the 14 active  
address bits to initialize the internal address counter and will  
shift out data residing at the corresponding location. If the  
Master does not acknowledge the data (NoACK) and then  
follows up with a STOP condition (Figure 11), the N24S128  
returns to Standby mode.  
Sequential Read  
If during a Read session the Master acknowledges the 1  
st  
Secure Data Page Lock Status Read  
data byte, then the N24S128 will continue transmitting data  
residing at subsequent locations until the Master responds  
with a NoACK, followed by a STOP (Figure 12). In contrast  
to Page Write, during Sequential Read the address count  
will automatically increment to and then wrap-around at end  
of memory (rather than end of page).  
There are two ways to check the lock status of the Security  
Sector. The first way is to initiate a Secure Data Page Write.  
The EEPROM will acknowledge if the Secure Data Page is  
unlocked, and it will not acknowledge if the Secure Data  
Page is locked. After the acknowledge bit, it is  
recommended to generate a Start condition followed by  
a Stop condition, to reset the interface.  
Secure Data Page Read  
The second way is to use a Lock Status Read instruction.  
This instruction is similar to a Selective Read instruction,  
but requires the use of the device address 1011b followed by  
the A2, A1, A0 bits. The master first sends a dummy write  
instruction followed by the address bytes specified in Table  
8 (xxxx x10x xxxx xxxx, where x is don’t care). This is  
followed by a read instruction using the same device address  
as above. The device will return a data byte where Bit 1  
indicates the lock status. If the lock is active this bit is “1”,  
otherwise it is “0”.  
The Secure Data Page Read instruction is similar to  
a Sequential Read instruction. To read data from a specific  
location within the Secure Data Page, the address counter is  
initialized by sending the device header and two address  
bytes as for a Secure Data Page Write instruction. This  
dummy write instruction is followed by an Immediate Read  
with the device header 1011b, and the device will shift back  
data from Secure Data Page. When the end of the Secure  
Data Page is reached, the address counter will wrap-around  
to zero, and the next byte returned will be the first byte in the  
page.  
Delivery State  
The N24S128 is shipped erased, i.e., all memory array  
bytes are FFh, and the settable Device Configuration bits set  
to 0 (1Dh).  
Device Configuration Register Read  
The Device Configuration Register Read instruction is  
similar to a Selective Read instruction. The user must send
