It's surprising they have both the "Titan M" security chip and a ST33J2M0 security microcontroller.

You would think just one would do for key storage. Skimming the hardware backed keystore overview, it only mentions one secure coprocessor: https://source.android.com/security/keystore

I was expecting see those chips mentioned in the video, but they didn't. Full tear down has them[1].
