 		 #126283 - Use 89S52 / 89S8252
Responding to: ???'s previous message
Mr. Arvind Shrivastava after going through your mails i gather that you are novoice for MCU , Embedded /assem level software ,FLASH/EEPROM programming.

So attempting to program FLASH of 89V51RD2 will be a very difficult task where younhave to bring in IAP area , use its function call for reading & write flash (and also disable interupts) , switch back to main program area , enable intrps .. many such things.

In the process IAP acn also be corrupted and not only your application won't run but also you have to load bootloader through parallel programming

I suggest that you use 89s8252 or 89252/53 where you can use 2k bytes data EEPROM more easily
