Apple has become a self-developed chip maniac! iPhone 11 U1 is a self-designed chip

According to foreign media reports, the disassembly analysis confirmed that the U1 chip in the iPhone 11 series was designed by Apple. Previously, it was speculated that the Apple U1 chip uses the Decawave ultra-wideband DW1000 chip, which has similar functions and can provide 10cm-level positioning accuracy.

Apple’s U1 chip is designed differently than the DW1000, but uses the same standard, so it will be compatible with third-party devices that use Decawave chips, iFixit said.

Originally thought to be licensed by Decawave, the chip was actually designed by Apple itself. “Apple designed its own 802.15.4z-compatible chipset that is interoperable with Decawave’s chips,” Decawave told iFixit in a statement.

In the past ten years, Apple has been called a “self-developed chip maniac”, launching a series of chips such as A, M, W, H, T, and S. This time the U1 is a brand new U-series chip.

Interestingly, Apple doesn’t appear to be a member of the UWB consortium, although Apple’s U1 chip is ultra-wideband (UWB) compliant, making it compatible with similar chips in other devices. Current members of the alliance include iRobot, Hyundai and Kia.

According to Apple’s official introduction, the newly designed U1 chip uses ultra-wideband technology, which enables the iPhone 11 Pro to have spatial awareness, which can sense other nearby Apple devices equipped with U1 chips and accurately determine the positional relationship of each other. another perception.

With the U1 chip and iOS 13, when using AirDrop, just point your iPhone at someone else’s iPhone and the system will prioritize them, allowing you to share files faster. Of course, this is just one use case, and more applications are yet to be developed. For example, Apple has not released the anti-lost product (Apple Tag), and it can only be said that it is more secure.
