Thanks for your reply. I am trying with that hex file only. Is there necessity of any specific crystal frequency. I am trying with 11.0592mhz and 8mhz.

I have worked with AT89S52 and used an external Flash(ISP) programmer, only hing is At89s52 doesn't have internal ISP(in system programmable), hence we need to get external programmer while comparing to atmega8,as it has internal ISP.

No consideration for crystal, if you want to work with 8051 architectured controller with ISP, I suggest Philips 8051 controller shich you can program using Flash programmer.

Check the link for ISP programmer to work with AT89S52.

You can find similar third party programmers with dealer.

I resolved this issue successfully. we should not use the lengthy cables from programmer to target board.
Feeling happy...
