24AA16H/24LC16BH

2.0 FUNCTIONAL DESCRIPTION

The 24XX16H supports a bidirectional, 2-wire bus and

data transmission protocol. A device that sends data

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

receiving data is defined 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

24XX16H works as slave. Both master and slave can

operate as transmitter or receiver, but the master

device determines which mode is activated.

3.0 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 when ever th e clock 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 (Figure 3-1).

3.1 Bus Not Busy (A)

Both data and clock lines remain high.

3.2 Start Data Transfer (B)

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

(SCL) is high determines a Start condition. All

commands must be preceded by a Start condition.

3.3 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.

3.4 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 clock pulse per

bit of data.

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, although only the last sixteen

will be stored when doing a write operation. When an

overwri te does occur it will replace da ta in a firs t-in first-

out (FIFO) fashion.

3.5 Acknowledge

Each receiving device, when addressed, is obliged to

generate an acknowledge after the reception of each

byte. Th e mast er device mus t ge nera te a n ex tra c lock

pulse which is associated with this Acknowledge bit.

The device that acknowledges, has to pull down the

SDA line d uring th e ackn owledge clock pulse in such 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. During reads, a master must signal an end of

data to t he slave by no t gene rating a n Ack nowledg e bit

on the las t by te tha t has be en c locked out of th e sl av e.

In this case, the slave (24XX16H) will leave the data

line high to enable the master to generate the Stop

condition.

FIGURE 3-1: DATA TRANSFER SEQUENCE ON THE SERIAL BUS

Note: The 24XX16H does not generate any

Acknowledge bits if an internal program-

ming cycle is in prog res s.

3.6 Device Addressing

A control byte is the first byte received following the

Start condition from the master device (Figure 3-2).

The con trol by te co nsi sts of a four-bi t c ontro l c od e. For

the 24XX 16H, th is is se t as ‘1010’ binary for read and

write op erat ions. The ne xt th ree bit s of th e co ntro l by te

are the bloc k-select bits (B2, B1, B0). They are used by

the master device to select which of the eight 256 word-

blocks of memory are t o be accessed. T hese bits are in

effect the three Most Significant bits of the word

address.

The last bit of the control byte defines the operation to

be performed. When set to ‘1’ a read operation is

selected. When set to ‘0’ a write operation is selected.

Following the Start condition, the 24XX16H monitors

the SDA bus, checking the device type identifier being

transmitted and, upon receiving a ‘1010’ code, the

slave device outputs an Acknowledge signal on the

SDA line. Depending on the state of the R/W bit, the

24XX16H will select a read or write operation.

4.0 WRITE OPERATION

4.1 Byte Write

Following the Start condition from the master, the

dev ice code ( 4 bits), the block address ( 3 bits) and the

R/W bi t, which is a logic-low, is placed o nto t he bus by

the master transmitter. This indicates to the addressed

slave receiver that a byte with a word address will

follow once it has generated an Ack nowledge bit d uring

the nint h clock cycl e. Therefor e, the next byt e transmit-

ted by the master is the word address and will be

written into the Address Pointer of the 24XX16H. After

receiving another Acknowledge signal from the

24XX16H, the master device will transmit the data word

to be written into the addressed memory location. The

24XX16H acknowledges again and the master

generates a Stop condition. This initiates the internal

write cycle and, during this time, the 24XX16H will not

generate Ackno w led ge sig na ls (Fig ure 4-1).

4.2 Page Write

The write control byte, word address and the first data

byte are transmitted to the 24XX16H in the same way

as in a byte write. However, instead of generating a

S top condition, the master transmits u p to 16 data bytes

to the 24XX 16H, which are temporarily stored in the on-

chip page buffer and will be written into memory once

the master has transmitted a Stop condition. Upon

receipt of each word, the four lower-order Address

Pointer bits are internally incremented by ‘1’. The

higher-order 7 bits of the word address remain

constant. If the master should transmit more than 16

words prior to generating the Stop condition, the

address counter will roll over and the previously

receive d dat a will be overwri tten. As w ith the by te write

operation, once the Stop condition is received an

internal write cycle will begin (Figure 4-2).

FIGURE 4-1: BYTE WRITE

FIGURE 4-2: PAG E WRITE

Note: Page write opera tions are l imited to wri ting

bytes within a single physical page,

regardless of the number of bytes

actually being written. Physical page

boundaries start at addresses that are

integer multiples of the page buffer size (or

‘pag e-siz e’) and end a t addre sses that a re

integer multiples of [page size – 1]. If a

Page Write command attempts to write

across a physical page boundary, the

result is that the data wraps around to the

beginning of the current page (overwriting

data previously stored there), instead of

being w ritten to the next page, as migh t be

expected. It is therefore necessary for the

application software to prevent page write

operations that would attempt to cross a

page boundary.

5.0 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

initiate s the internally-timed write cycle and ACK polling

can then be initiated immediately. This involves the

master sending a S tart c ondition fo llowed by t he control

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

busy wi th the write cycle, no ACK will be returned. If the

cycle is complete, the device will return the ACK and

the master can then proceed with the next Read or

Write command. See Figure 5-1 for a flow diagram of

this operation.

6.0 WRITE PROTECTION

The WP pin allows the user to write-protect half of the

array (400h -7FFh) when the pi n is tied to VCC. If the pin

24AA16H/24LC16BH

7.0 READ OPERATION

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 ‘1’. There are three basic types

of read operat ions: current address read , rand om rea d

and sequential read.

7.1 Current Address Read

The 24XX16H contains an address counter that main-

tains the address of the last word accessed, internally

incremented by ‘1’. Therefore, if the previous access

(either a read or write operation) was to address n, the

next curren t addre ss read operati on would access da ta

from address n + 1. Upon receipt of the slave address

with R/W bit set to ‘1’, the 24X X16H issues an acknowl-

edge and tran smits the 8-bit dat a word. The maste r will

not acknowledge the transfer , but does gene rate a Stop

condition and the 24XX16H discontinues transmission

(Figure 7-1) .

7.2 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 ratio n, the word add res s mus t firs t

be set. This is accomplished by sending the word

address to the 24XX16H as part of a write operation.

Once th e word address is s ent, the master ge nerates a

Start condition following the acknowledge. This

terminates the write operation, but not before the

internal Address Pointe r is se t. The m aster th en issue s

the control byte again, but with the R/W bit set to a ‘1’.

The 24XX16H will then issue an acknowledge and

transmit the 8-bit data word. The master will not

acknowledge the transfer, but does generate a Stop

condition and the 24XX16H will discontinue transmis-

sion (Fig ure 7 -2).

7.3 Sequentia l Read

Sequential reads are initiated in the same way as a

random read, exc ep t tha t once the 2 4XX1 6H tran sm its

the first data byte, the master issues an acknowledge

as opposed to a Stop condition in a random read. This

directs the 24XX16H to transmit the next sequentially-

addressed 8-bit word (Figure 7-3).

To provide sequen tia l rea ds , the 24 XX16H c ontains a n

internal Address Pointer that is incremented by one

upon completion of each operation. This Address

Pointer allows the entire memory contents to be serially

read during one operation.

7.4 Noise Protection

The 24XX16 H employs a VCC threshold detector circuit

which disables the internal erase/write logic if the VCC

is below 1.5V at nominal conditions.

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.

8.0 PIN DESCRIPTIONS

The descriptions of the pins are listed in Table 8-1.

TABLE 8-1: PIN FUNCTION TABLE

8.1 Serial Address/Data Input/Output

(SDA)

SDA is a bidirectional pin used to transfer addresses

and data into and out of the de vice . Sinc e it i s an open-

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

to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz).

For normal data transfer, SDA is allowed to change

only during SCL low. Changes during SCL high are

reserved for indicating Start and Stop conditions.

8.2 Serial Clock (SCL)

The SCL in pu t is u se d to s ynchro ni ze th e da t a tra ns fer

to and from the device.

8.3 Wr it e-Protect (WP)

The WP pin must be connected to either VSS or VCC.

If tied to VSS, normal memory operation is enabled

(read/wri te the ent ire memory 000h -7FFh ).

If tied to VCC, wri te op era t io n s are in hi b it e d, ha l f o f t he

memory will be write-protected (400h-7FFh). Read

operations are not af fec ted.

8.4 A0, A1, A2

The A0, A1 and A2 pins are not used by th e 24XX16H.

They may be left floating or tied to either VSS or VCC.
