problem with pic18f4620 with eeprom 24lc512 via i2c

[pratik345]

hi i want to communicate 24lc512 with pic18f4620...
but i cant communicate with it....

code provided by mikroelectronica is perfectly work with eeprom 24c02. but cant communicate with 24lc512...

so wat change i should to do..

here the code for 24c02 eeprom
its perfectly working....

sbit sw at RA0_bit;
sbit sw_Direction at TRISA0_bit;

void main()
{

unsigned char i;
PORTD = 0;
TRISD = 0;
PORTA = 0; // Configure PORTB as output
TRISA = 1;
ADCON1=0x0F;

I2C1_Init(100000); // initialize I2C communication
for(i=0;i<16;i++)
{
I2C1_Start(); // issue I2C start signal
I2C1_Wr(0xA2); // send byte via I2C (device address + W)
I2C1_Wr(i); // send byte (address of EEPROM location)
I2C1_Wr(i); // send data (data to be written)
I2C1_Stop(); // issue I2C stop signal
Delay_ms(1000);
}
Delay_ms(1000);

i=0;
for(i=0;i<16;i++)
{
if(sw == 0)
{
delay_ms(10);
if(sw==0)
{
delay_ms(2000);
pause: if(sw==0)
{
delay_ms(10);
if(sw==0)
{
goto start;
}
}
goto pause;
}
}


start:I2C1_Start(); // issue I2C start signal
I2C1_Wr(0xA2); // send byte via I2C (device address + W)
I2C1_Wr(i); // send byte (data address)
I2C1_Repeated_Start(); // issue I2C signal repeated start
I2C1_Wr(0xA3); // send byte (device address + R)
PORTD = I2C1_Rd(0u); // Read the data (NO acknowledge)
I2C1_Stop();
Delay_ms(1000); // issue I2C stop signal

}
}
