sushil;
try contacting mr.thakurdesai at philips
semiconductors in mumbai.i shall post his email id on the forum by monday(i have his card in my mumbai office,so have to wait) or post your mail id here.shall mail it to u by monday.

my advice is don't purchase any chip in pune unless you need very small quantity.pune dealers handle low volumes so charge anything.i have had that experience.

regards
pranav
