1. The E2 input is not connected to a ball, therefore E2 input is decoded as “0” (see also Section 2.4: Write  
Control (WC)).  
Caution:  
As EEPROM cells lose their charge (and so their binary value) when exposed to ultra violet  
(UV) light, EEPROM dice delivered in wafer form or in WLCSP package by  
STMicroelectronics must never be exposed to UV light.

Signal description  
2.1  
Serial Clock (SCL)  
The signal applied on the SCL input is used to strobe the data available on SDA(in) and to  
output the data on SDA(out).  
2.2  
Serial Data (SDA)  
SDA is an input/output used to transfer data in or data out of the device. SDA(out) is an open  
drain output that may be wire-OR’ed with other open drain or open collector signals on the  
bus. A pull-up resistor must be connected from Serial Data (SDA) to V (Figure 11  
CC  
indicates how to calculate the value of the pull-up resistor).  
2.3  
2.4  
Chip Enable (E2)  
This input signal is used to set the value that is to be looked for on the bit b3 of the device  
select code. This input must be tied to V or V , to establish the device select code as  
shown in Table 2. When not connected (left floating), this input is read as low (0).  
CC  
SS  
Write Control (WC)  
This input signal is useful for protecting the entire contents of the memory from inadvertent  
write operations. Write operations are disabled to the entire memory array when Write  
Control (WC) is driven high. Write operations are enabled when Write Control (WC) is either  
driven low or left floating.  
When Write Control (WC) is driven high, device select and address bytes are  
acknowledged, Data bytes are not acknowledged.  
2.5  
VSS (ground)  
V
is the reference for the V supply voltage.

2.6  
Supply voltage (VCC)  
2.6.1  
Operating supply voltage V  
CC  
Prior to selecting the memory and issuing instructions to it, a valid and stable V voltage  
CC  
within the specified [V (min), V (max)] range must be applied (see Operating conditions  
CC  
CC  
in Section 8: DC and AC parameters). In order to secure a stable DC supply voltage, it is  
recommended to decouple the V line with a suitable capacitor (usually of the order of  
CC  
10 nF to 100 nF) close to the V /V package pins.  
CC SS  
This voltage must remain stable and valid until the end of the transmission of the instruction  
and, for a write instruction, until the completion of the internal write cycle (t ).

Signal description  
2.6.2  
Power-up conditions  
The V voltage has to rise continuously from 0 V up to the minimum V operating voltage  
CC  
CC  
(see Operating conditions in Section 8: DC and AC parameters) and the rise time must not  
vary faster than 1 V/µs.  
2.6.3  
Device reset  
In order to prevent inadvertent write operations during power-up, a power-on-reset (POR)  
circuit is included.  
At power-up, the device does not respond to any instruction until V has reached the  
CC  
internal reset threshold voltage. This threshold is lower than the minimum V operating  
CC  
voltage (see Operating conditions in Section 8: DC and AC parameters). When V passes  
CC  
over the POR threshold, the device is reset and enters the Standby Power mode; however,  
the device must not be accessed until V reaches a valid and stable DC voltage within the  
CC  
specified [V (min), V (max)] range (see Operating conditions in Section 8: DC and AC  
CC  
CC  
parameters).  
In a similar way, during power-down (continuous decrease in V ), the device must not be  
CC  
accessed when V drops below V (min). When V drops below the threshold voltage,  
CC  
CC  
CC  
the device stops responding to any instruction sent to it.  
2.6.4  
Power-down conditions  
During power-down (continuous decrease in V ), the device must be in the Standby Power  
CC  
mode (mode reached after decoding a Stop condition, assuming that there is no internal  
write cycle in progress).

Device operation  
2
The device supports the I C protocol. This is summarized in Figure 5. Any device that sends  
data on to the bus is defined to be a transmitter, and any device that reads the data to be a  
receiver. The device that controls the data transfer is known as the bus master, and the  
other as the slave device. A data transfer can only be initiated by the bus master, which will  
also provide the serial clock for synchronization. The device is always a slave in all  
communications.

Device operation  
M24C08-W M24C08-R M24C08-F  
4.1  
Start condition  
Start is identified by a falling edge of Serial Data (SDA) while Serial Clock (SCL) is stable in  
the high state. A Start condition must precede any data transfer instruction. The device  
continuously monitors (except during a Write cycle) Serial Data (SDA) and Serial Clock  
(SCL) for a Start condition.  
4.2  
Stop condition  
Stop is identified by a rising edge of Serial Data (SDA) while Serial Clock (SCL) is stable  
and driven high. A Stop condition terminates communication between the device and the

condition to force the device into the Standby mode.  
A Stop condition at the end of a Write instruction triggers the internal Write cycle.

Data input  
During data input, the device samples Serial Data (SDA) on the rising edge of Serial Clock  
(SCL). For correct device operation, Serial Data (SDA) must be stable during the rising edge  
of Serial Clock (SCL), and the Serial Data (SDA) signal must change only when Serial Clock  
(SCL) is driven low.  
Acknowledge bit (ACK)  
The acknowledge bit is used to indicate a successful byte transfer. The bus transmitter,  
whether it be bus master or slave device, releases Serial Data (SDA) after sending eight bits  
th  
of data. During the 9 clock pulse period, the receiver pulls Serial Data (SDA) low to  
acknowledge the receipt of the eight data bits.

Device addressing  
To start communication between the bus master and the slave device, the bus master must  
initiate a Start condition. Following this, the bus master sends the device select code, shown  
in Table 2 (on Serial Data (SDA), most significant bit first).

The 8 bit is the Read/Write bit (RW). This bit is set to 1 for Read and 0 for Write operations.  
If a match occurs on the device select code, the corresponding device gives an  
th  
acknowledgment on Serial Data (SDA) during the 9 bit time. If the device does not match  
the device select code, it deselects itself from the bus, and goes into Standby mode.

Write operations  
Following a Start condition the bus master sends a device select code with the R/W bit (RW)  
reset to 0. The device acknowledges this, as shown in Figure 6, and waits for the address  
byte. The device responds to each address byte with an acknowledge bit, and then waits for  
the data byte.

When the bus master generates a Stop condition immediately after a data byte Ack bit (in  
th  
the “10 bit” time slot), either at the end of a Byte Write or a Page Write, the internal Write  
cycle t is triggered. A Stop condition at any other time slot does not trigger the internal  
W
Write cycle.  
After the Stop condition and the successful completion of an internal Write cycle (t ), the  
W
device internal address counter is automatically incremented to point to the next byte after  
the last modified byte.  
During the internal Write cycle, Serial Data (SDA) is disabled internally, and the device does  
not respond to any requests.  
If the Write Control input (WC) is driven High, the Write instruction is not executed and the  
accompanying data bytes are not acknowledged, as shown in Figure 7.

Byte Write  
After the device select code and the address byte, the bus master sends one data byte. If  
the addressed location is Write-protected, by Write Control (WC) being driven high, the  
device replies with NoAck, and the location is not modified. If, instead, the addressed  
location is not Write-protected, the device replies with Ack. The bus master terminates the  
transfer by generating a Stop condition, as shown in Figure 6.

Page Write  
The Page Write mode allows up to 16 bytes to be written in a single Write cycle, provided  
that they are all located in the same page in the memory: that is, the most significant  
memory address bits, A9/A4, are the same. If more bytes are sent than will fit up to the end  
of the page, a “roll-over” occurs, i.e. the bytes exceeding the page end are written on the  
same page, from location 0.  
The bus master sends from 1 to 16 bytes of data, each of which is acknowledged by the  
device if Write Control (WC) is low. If Write Control (WC) is high, the contents of the  
addressed memory location are not modified, and each data byte is followed by a NoAck, as  
shown in Figure 7. After each transferred byte, the internal page address counter is  
incremented.  
The transfer is terminated by the bus master generating a Stop condition.

Minimizing Write delays by polling on ACK  
The maximum Write time (tw) is shown in AC characteristics tables in Section 8: DC and AC  
parameters, but the typical time is shorter. To make use of this, a polling sequence can be  
used by the bus master.  
The sequence, as shown in Figure 8, is:  
Initial condition: a Write cycle is in progress.  
Step 1: the bus master issues a Start condition followed by a device select code (the  
first byte of the new instruction).  
Step 2: if the device is busy with the internal Write cycle, no Ack will be returned and  
the bus master goes back to Step 1. If the device has terminated the internal Write  
cycle, it responds with an Ack, indicating that the device is ready to receive the second  
part of the instruction (the first byte of this instruction having been sent during Step 1).

Read operations  
Read operations are performed independently of the state of the Write Control (WC) signal.  
After the successful completion of a Read operation, the device internal address counter is  
incremented by one, to point to the next byte address.  
For the Read instructions, after each byte read (data out), the device waits for an  
acknowledgment (data in) during the 9th bit time. If the bus master does not acknowledge  
during this 9th time, the device terminates the data transfer and switches to its Standby  
mode.

5.2.3  
Random Address Read  
A dummy Write is first performed to load the address into this address counter (as shown in  
Figure 9) but without sending a Stop condition. Then, the bus master sends another Start  
condition, and repeats the device select code, with the RW bit set to 1. The device  
acknowledges this, and outputs the contents of the addressed byte. The bus master must  
not acknowledge the byte, and terminates the transfer with a Stop condition.  
Current Address Read  
For the Current Address Read operation, following a Start condition, the bus master only  
sends a device select code with the R/W bit set to 1. The device acknowledges this, and  
outputs the byte addressed by the internal address counter. The counter is then  
incremented. The bus master terminates the transfer with a Stop condition, as shown in  
Figure 9, without acknowledging the byte.  
Sequential Read  
This operation can be used after a Current Address Read or a Random Address Read. The  
bus master does acknowledge the data byte output, and sends additional clock pulses so  
that the device continues to output the next byte in sequence. To terminate the stream of  
bytes, the bus master must not acknowledge the last byte, and must generate a Stop  
condition, as shown in Figure 9.  
The output data comes from consecutive addresses, with the internal address counter  
automatically incremented after each byte output. After the last memory address, the  
address counter “rolls-over”, and the device continues to output data from memory address  
00h.

Initial delivery state  
The device is delivered with all the memory array bits and Identification page bits set to 1  
(each byte contains FFh).

rising edge of SDA.  
4. tCLQV is the time (from the falling edge of SCL) required by the SDA bus line to reach either 0.3 VCC or  
0.7 VCC, taking into account the Rbus × Cbus time constant specific to the end application.  
5. For a reStart condition, or following a Write cycle.
