#3LD3 chip

A recent leak of the iPhone 15 Plus’ USB-C port component shows an Apple-made '3LD3' chip. You can see the packaged chip on the iPhone 15 series. Because it is a self-designed chip, the function cannot be judged by the model. Judging from the same type of plastic packaged chips in the past, it may be the setting of transmission encryption. pic.twitter.com/YSM1guM3n9 — Majin Bu (@MajinBuOfficial) August 14, 2023 While it is unclear whether this chip is solely for security or impose limitations, the leaker Majin Bu has a theory. That the chip may serve as transmission encryption—providing encryption features to protect the iPhone from data compromise. At the same time, the chip may hinder USB-C's functionality and prevent it from reaching its full potential on the iPhone. This supports the possibility that the 3LD3 chip is able to identify an Apple USB-C cable and compatible adapters.
