Not sure, but could it be a "transponder", in form of a small glass tube
with coil and small IC inside, my FORD remote key has one, if I remove it
from the key the car won't start.

The PCF prefix denotes a Philips Semi (now nxp) part. As the NXP site
truly sucks, it may not be exporting the appropriate pages via google or
other engines.

I suggest you look at nxp, if you can stomach the useless flash and crap.

http://www.nxp.com/index.html

I now refuse to use their parts - I can't even navigate the site without
javascript and flash enabled.

It's possible the part was made by Philips (now NXP) for a specific OEM
under contract and therefore has the Philips prefix but is not available
to a general public search.

This was a Philips (now NXP) part.
It has not been offered for about six years.
It is described as a "secured program, readwrite transponder" according to
DN44 on the NXP site.
