2.0 PIN DESCRIPTIONS

2.1 SDA Serial Data

This is a bidirectional pin used to transfer addresses

and data into and data out of the device. It is an open

drain terminal, therefore the SDA bus requires a pull-up

resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for

400 kHz).

For norma l data trans fer SDA is all owed to change only

during SCL low. Changes during SCL high are

reserved for indicating the Start and Stop conditions.

2.2 SCL Serial Clock

This i nput is u sed t o sy nchron ize the d ata trans fer fro m

and to the device.

2.3 Noise Protection

The SCL and SDA inputs have Schmitt Trigger and

filter circuits which suppress noise spikes to assure

proper device operation even on a noisy bus.

3.0 FUNCTIONAL DESCRIPTION

The 24XX00 supports a bidirectional 2-wire bus and

data transmission protocol. A device that sends data

onto the bus is defined as a transmitter, and a device

receiving data as a receiver. The bus has to be

controlled by a master device which generates the

Serial Clock (SCL), controls the bus access, and

generates the Start and Stop conditions, while the

24XX00 works as slave. Both master and slave can

operate as transmitter or receiver, but the master

device determines which mode is activated.

4.0 BUS CHARACTERISTICS

The following bus protocol has been defined:

• Data transfer may be initiated only when the bus

is not busy.

• During data transfer, the data line must remain

stab le whene ver the cl ock lin e is high . Change s in

the data line while the clock line is high will be

interpreted as a Start or Stop condition.

Accordingly, the following bus conditions have been

defined (Fig ure 4-1).

4.1 Bus Not Busy (A)

Both data and clock lines remain high.

4.2 Start Data Transfer (B)

A hig h- to - lo w t ran si t i on of t h e SD A l in e whi l e t h e c lo ck

(SCL) is high determines a Start condition. All

commands must be preceded by a Start condition.

4.3 S top Data Transfer (C)

A low-to-high transition of the SDA line while the clock

(SCL) is high determines a Stop condition. All

operations must be ended with a Stop condition.

4.4 Data Valid (D)

The state of the data line represents valid data when,

after a Start condition, the data line is stable for the

duration of the high period of the clock signal.

The data on the line must be changed during the low

period of the clock signal. There is one bit of data per

clock pulse.

Each dat a transf er is initiated w ith a S tart condition an d

terminated with a Stop condition. The number of the

data bytes transferred between the Start and Stop

conditions is determined by the master device and is

theoretically unlimited.

24AA00/24LC00/24C00

4.5 Acknowledge

Each receiving device, when addressed, is obliged to

generate an acknowledge after the reception of each

byte. The master device must generate an extra clock

pulse which is associated with this Acknowledge bit.

The device that acknowledges has to pull down the

SDA line du ring the Acknow ledge cl ock pulse in s uch a

way that the SDA line is stable low during the high

period of the acknowledge related clock pulse. Of

course, setup and hold times must be taken into

account. A master must signal an end of data to the

slave by no t g ene rati ng an Ackno wled ge bi t on the las t

byte that has been clocked out of the slave. In this

case, the slave must leave the data line high to enable

the maste r to gen erat e the Stop condition (Figur e 4-2).

5.0 DEVICE ADDRESSING

After generating a Start condition, the bus master

transmits a control byte consisting of a slave address

and a Read/Write bit that indicates what type of

operatio n is to be perfo rmed. The slave add ress for the

24XX00 consists of a 4-bit device code ‘1010’ followed

by three “don’t care” bits.

The last bi t of the control byte determines the operation

to be perfo rme d. When set to a o ne a read operati on is

selected, and when set to a zero a write operation is

selected (Figure 5-1). The 24XX00 monitors the bus for

its corresponding slave address all the time. It

generate s an Ackn owledge bit if the s lave add ress was

true and it is not in a programming mode.

FIGURE 5-1: CONTROL BYTE FORMAT

6.0 WRITE OPERATIONS

6.1 Byte Write

Following the Start signal from the master, the device

code (4 bits), the “don’t care” bits (3 bits), and the R/W

bit (which is a logic low) are placed onto the bus by the

master transmitter. This indicates to the addressed

slave receiver that a byte with a word address will

follow after it has genera ted an Acknowl edge bit durin g

the nint h clock cycl e. Therefo re, the next byte transmit-

ted by the master is the word address and will be

written into the Address Pointer of the 24XX00. Only

the low er four ad dress bits are us ed by the d evice , and

the upper four bits are “don’t cares.” The 24XX00 will

acknowledge the address byte and the master device

will then transmit the data word to be written into the

addressed memory location. The 24XX00 acknowl-

edges again and the master generates a Stop

condition. This initiates the internal write cycle, and

during this time the 24 XX00 will not ge nerate Ack nowl-

edge si gnals (Fi gure 7-2). Af ter a byte W rite comman d,

the internal address counter will not be incremented

and will point to t he same address location that was just

written. If a Stop bit is transmitted to the device at any

point in t he W rite comm and seque nce before the entire

sequence is complete, then the command will abort

and no data will be written. If more than 8 data bits are

transmitted before the Stop bit is sent, then the device

will clear the previously loaded byte and begin loading

the data buffer again. If more than one data byte is

transmitted to the device and a Stop bit is sent before a

full eight data bits have been transmitted, then the

Write command will abort and no data will be written.

The 24XX00 employs a VCC threshold detector circuit

which disables the internal erase/write logic if the VCC

is below 1.5V (24AA00 and 24LC00) or 3.8V (24C00)

at nominal conditions.

7.0 ACKNOWLEDGE POLLING

Since the device will not acknowledge during a write

cycle, this can be used to determine when the cycle is

complete (this feature can be used to maximize bus

throughput). Once the Stop condition for a Write

comma nd has been is sued from the master , the device

initiates the internally timed write cycle. ACK polling

can be initiated immediately. This involves the master

sending a Start condition followed by the control byte

for a Write command (R/W = 0). If the device is still

busy with the write cycle, then no ACK will be returned.

If no AC K is retu rned, then the S t art bit and cont rol byte

must be re-sent. If the cycle is complete, then the

device will return the ACK and the master can then

proceed with the next Read or Write command. See

Figure 7-1 for flow diagram.

8.0 READ OPERATIONS

Read operations are initiated in the same way as write

operations with the exception that the R/W bit of the

slave address is set to one. Ther e are three ba sic types

of read operat ions: current add ress read , rand om rea d

and sequential read.

8.1 Current Address Read

The 24XX00 contains an address counter that main-

tains the address of the last word accessed, internally

incremented by one. Therefore, if the previous read

access was to address n, the next current address read

operatio n wou ld acc ess dat a fr om add ress n + 1. U pon

receipt of the slav e address w ith the R/W b it set to one,

the device issues an acknowledge and transmits the

eight-bit data word. The master will not acknowledge

the transfer , but do es generate a S top condition and the

device discontinues transmission (Figure 8-1).

8.2 Random Read

Random read operations allow the master to access

any memory location in a random manner. To perform

this typ e of re ad ope ration, first the wo rd address mus t

be set. This is done b y sending the word address to the

device as part of a write operation.

After the word address is sent, the master generates a

Start condition following the acknowledge. This termi-

nates the write operation, but not before the internal

Address Pointer is set. Then the master issues the

control byte again, but with the R/W bit set to a one.

The 24XX00 will the n issue an a cknowled ge and trans -

mits the eight bit data word. The master will not

acknowledge the transfer, but does generate a Stop

condition and the device discontinues transmission

(Figure 8-2). After this command, the internal address

counter will point to the address location following the

one that was jus t read.

8.3 Sequentia l Read

Sequential reads are initiated in the same way as a

random read except that after the device transmits the

first data byte, the master issues an acknowledge as

opposed to a Stop condition in a random read. This

directs the device to transmit the next sequentially

addressed 8-bit word (Figure 8-3).

To provide sequential reads the 24XX00 contains an

internal Address Pointer which is incremented by one

at th e co mplet ion o f eac h r ead o peratio n. Thi s Add ress

Pointer allows the entire memory contents to be serially

read during one operation.
