Actually, this is untrue, and I know of no NFC ASIC with an integrated secure element (not NXP, nor Sony); the ASICs are typically just transceivers (the exception being an NXP ASIC with embedded MiFare). The SIM has been identified for a long time as the probable security element for NFC. However, this has long been a point of contention, and Gemalto (the largest SIM provider in the world) has been playing both sides quite evenly.

"Featuring a NFC radio controller and an embedded Secure Element, the PN65N is also fully validated and integrated on the latest release of Android™ 4.0."

You used the word "typically," and as you can imagine, the telcos have a preference for treating the SIM as the secure element because they control it; in the US the telcos dirve the majority of mobile sales. This is a slightly sore subject as I worked for a startup that is now a zombie, having attempted to wait out the fight over who would control NFC payments (telco vs. credit card company). Look at the just announced chip from Broadcom which supports "multiple secure elements to ensure all payment business models are supported for today's market.": http://seekingalpha.com/news-article/5050981-broadcom-launches-industry-s-first-certified-nfc-quad-combo-wireless-connectivity-solution http://seekingalpha.com/news-article/5050981-broadcom-launch...
