Vinod,
You tried and couldn't fetch the chip. Anyways If you try really sincerelly then certainly you would have got it. [ Dhoondhne se to bhagwan mil jata hai ]. There is an atmel distributor Oriole Electronics at ghatkopar Mumbai. They stock all atmel IC's and certainly they must me having these chips and even if they don't have ready in stock certainly they can import the IC's and sell you.
