Philips/NXP micro with RF txmitter and RFID

I'm looking at a 315MHz car remote with integrated 125kHz RFID PATS
transponder, and trying to find out some more about the single-chip
solution they're using. It's Philips-branded but very hard to read.
The FCC registration data describes it as a "STARC2XL"
microcontroller.

Browsing NXP's junkpile of a web site has not led me to any RF-
containing micros at all; can anyone provide me with part numbers,
even just of transmitter+micro combo ICs? (I'm aware of uChip, Chipcon
and Atmel offerings, inter alia - but I'm interested in looking at
Philips' lineup as well).

Not all Philips parts are made by NXP.
How many pins, and how much of the device can you read.
( and underneath the package ? )

I can't remove it from the board, but the top has a Philips logo and
(I just opened another unit, which is a bit more legible):

(----- is apparently 5 illegible characters)

It's a 20-SSOP. I'm told it's probably a PCF7941.

Hi,
did you look at this one?
