ration used by the IIC interface compared to that of the

MICROWIRE™ and SPI interface, reduced board space and pin

count allows the designer to have more creative flexibility while

reducing interconnecting cost.

INTRODUCTION

Fairchild Semiconductor’s NM24C EEPROMs are designed to

interface with Inter-Integrated Circuit (IIC) buses and hardware.

Fairchild’s electrically erasable programmable read only memo-

ries (EEPROMs) offer valuable security features (write protec-

tion), two write modes, three read modes and a wide variety of

memory sizes. Applications for the IIC bus and NM24C memories

are included in SANs (small-area networks), stereos, televisions,

automobiles and other scaled-down systems that don’t require

tremendous speeds but instead cost efficiency and design sim-

plicity.

OPERATING Fairchild SEMICONDUCTOR’S

NM24Cs

TheNM24CE²PROMsrequireonlysixsimpleoperatingcodesfor

transmittingorreceivingbitsofinformationoverthe2-wireIICbus.

These fields are explained in greater detail below and briefly

described hereafter: a start bit, a 7-bit slave address, a read/write

bit which defines whether the slave is a transmitter or receiver, an

acknowledge bit, message bits divided into 8-bit segments and a

stop bit.

IIC BACKGROUND

The IIC bus configuration is an amalgam of microcontrollers and

peripheral controllers. By definition: a device that transmits sig-

nalsontotheIICbusisthe“transmitter”andadevicethatreceives

signals is the “receiver”; a device that controls signal transfers on

thelineinadditiontocontrollingtheclockfrequencyisthe“master”

and a device that is controlled by the master is the “slave”. The

master can transmit or receive signals to or from a slave, respec-

tively, or control signal transfers between two slaves, where one

is the transmitter and the other is the receiver. It is possible to

combineseveralmasters,inadditiontoseveralslaves,ontoanIIC

bus to form a multimaster system. If more than one master

simultaneously tries to control the line, an arbitration procedure

decides which master gets priority. The maximum number of

devices connected to the bus is dictated by the maximum allow-

able capacitance on the lines, 400 pF, and the protocol’s address-

ing limit of 16k; typical device capacitance is 10 pF. Up to eight

E²PROMs can be connected to an IIC bus, depending on the size

of the memory device implemented.

For efficient and faster serial communication between devices,

the NM24C Family features page write and sequential read.

TheNM24C03/C05/C09/C16/C17Familyoffersasecurityfeature

in addition to standard features found in the NM24C02/C04/C08/

C16Family. Thesecurityfeatureisbeneficial inthatitallowsRead

Only Memory (ROM) to be implemented in the upper half of the

memory to prevent any future programming in that particular chip

section; the remaining memory that has not been write protected

can still be programmed. The security feature in the NM24C03/

C05/C09/C17 Family does not require immediate implementation

when the device is interfaced to the IIC bus, which gives the

designer the option to choose this feature at a later date. Table 1

COP8™ Microcontroller Family is listed in a latter section of this

application note for further information to the reader.

Simplicity of the IIC system is primarily due to the bidirectional 2-

wire design, a serial data line (SDA) and serial clock line (SKL),

and to the protocol format. Because of the efficient 2-wire configu-
