Dear Hariharan,

I have spent enough time to test 24LC512 EEPROM with LPC2148. I have written post and shared complete source code and circuit diagram. If I write all little details again here then I will run out of time. Here is link: http://www.binaryupdates.com/i2c-in-lpc2148-arm7-microcontroller/

If in case you have any question then feel free to write me.

Good Luck !!!

Thank you for your reply sir,
                                  I already have that code bundle but in those I2C folder abstract shows, it has interface with PCF8594C-2 EEPROM. I want to interface with at24c256 EEPROM, so i want to know it is possible or not. I have to run I2C program in keil and debug with I2C0 interface, when the program run it has not displayed proper protocol status, it only displayed device address and negative ACK only. I have to tried with proteus software to simulate, it  also displayed and hold start condition only.
Here as i attached response window of keil and proteus.
