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).
