RFID tag hardware

[Dimitris Stafylarakis]

Hi,
I'm looking for an RFID tag Analog Front-End IC, if any, to connect to a
microcontroller. Up to now, I've found some separate chips but they were all
for reader designs, not for the tag. Otherwise, any advice on building it
out of discrete components could help.

Thanx in advance

What are you trying to accomplish?

I've done analog chip designs for Intermec, SAVI and Single Chip
Systems. I don't think ANY of them will sell you a chip.

I love to cook with wine. Sometimes I even put it in the food.

what kind of RFID? HF or UHF?

This is about an MSc thesis project and is dealing with PHILIPS ICODE
readers (thus 13.56 MHz). I want to play with a tag's crypto
capabilities and therefore use a tag analog front-end with my own code
in a microcontroller. I guess this being an MSc project and all, won't
change much in those companies' attitude right (Jim?)?

Maybe, maybe not. Write to them on official university stationery
pleading your case. Imply that your thesis might uncover something
useful for them. Who knows, you might get a bunch of samples.
