OVERVIEW

This Project is an MICRO CONTROLLER based i.e.,

using EMBEDDED technology.

Deals with writing the details of an student into a

SMART CARD and read it to display them on LCD.

We will come to know finally how smart card became

‘ SMART ’

SMART CARD

Smart Card is a small plastic intelligent token

embedded with an IC chip that makes it

‘SMART’.

Processing power is more.

They have larger storage capacity

They are appropriate for secure and convenient

data storage.

Replacement of Bar Codes and Magnetic Strips

INTERNAL BLOCK DIAGRAM

SMART CARD (SLE-4442)

FEATURES

256 8-bit EEPROM organization

Byte-wise addressing

32 1-bit organization of protection memory

Answer-to-Reset acc. to ISO standard 7816-3

Programming time 2.5 ms per byte for both

erasing and writing

Data retention for minimum of ten years

PIN CONFIGURATION

STANDARDS

ISO7816 is the international standard for Smart

Cards that use electrical contacts.

With this standard, Smart Cards could communicate

with the Reader using the same protocol.

ISO7816 standards are separated in 3 different parts.

1. ISO7816-1

2. ISO7816-2

3. ISO7816-3

Insert Smart card

1st Pin Of µC is Low

Arrange data array

Read Data from SC

Send them to LCD

OPERATION OVERVIEW

APPLICATIONS OF SMART CARD

Student Identification

Financial Applications

Communications Applications

Government Programs

Information Security

Physical Access Control

Transportation

MICROCONTROLLER (89C51)

FEATURES

80C51 Central Processing Unit

Crystal frequency:11.092Mhz

Voltage: 5v

Speed up to 33 MHz

Four 8-bit I/O ports

Internal RAM: 128 bytes

External RAM: 64 Kbytes

Presence of FLASH memory: 4Kbytes

SFR USED

Accumulator

Timer 0 for checking smart card insertion

Timer 1 for serial communication

TMOD (For setting Timer Mode )

IE (Interrupt Enable)

LIQUID CRYSTAL DISPLAY

Intelligent display of two lines, 20 characters per

line

Two internal byte-wide registers,

Commands Display (RS=0)

Characters Display (RS=1).

Contains RAM (user programmable)

LCD bit 7 is used for busy check.

KEIL SOFTWARE

C language

Used for configure the Microcontroller to work

according to our project

For .Hex Files

Used to Dump the CODE written in the assembly

language

‘Hex’ files are used

Converts the character (AL) into binary (MC)

FLASH MAGIC

UPDATE MAIN MEMORY

void main()

{

Update data(' ');

while(1);

}

if(!VCC)

{

z=1;

while(z)

{

lcd_cmd(0x01);

lcd_cmd(0x80);

string_display("NAME:");

t=0x25;

while(hexnum[t]!=‘ ‘)

{

lcd_data(hexnum[t]);

t++;

}

READ MAIN MEMORY

Digital data is sent through RS 232 protocol.

Specifications of RS232:

Length of cable:15mt

data voltage: -15v to 15v

1(-3 to -25V)

0 (3 to 25V)

Baud rate: 9600bytes/sec

MAX232 is connected to cable to convert 30v to

5v to send data into the microcontroller

SERIAL COMMUNICATION (RS232)

POWER SUPPLY

Center tapped transformer (12-0-12)

Power flow:

230v ac, 50hz adaptor12v dc,

1.25mAregulator5v dc

POWER SUPPLY SPECIFICATIONS

CONCLUSION

The project has been successfully

designed and code was written using assembly

language and student’s data was written and

displayed for few fields.

Secondly, using highly advanced IC’s

and with the help of growing technology the

project has been successfully implemented.

OVERVIEW OF MICROCONTROLLER

Basic Building Block of any EMBEDEDD System

Consists internally a Microprocessor, I/O Devices

and Internal Memory

Only on a single chip all the Components are

fabricated

Many additional features comparatively to an

Microprocessor

Can be used perfectly for a specific task to

perform

Simply a Micro CPU

ADVANTAGES

The capacity provided by the on-board

microprocessor and data capacity for highly secure

Track recording

Durability

Chip Operating Systems (multiple applications)

Secure on a Single Chip

FUTURE ASPECTS

Use of Biometrics.

Online shopping.

Multifunctional
