Chipworks has actually done an outstanding quantity of investigatory work with the Apple Watch and also has managed to identify that the gadget appears to include a BCM4334 Wi-Fi chip from Broadcom.
Chipworks identified the chip in the video introduction of the Apple Watch, which shows Apple’s custom made S1 Apple Watch chip in different layers. Based on screenshots from the video, Chipworks figured out that of the chips to the top of the processor chip looked like a Wi-Fi chip. The design particularly paired up with the Broadcom BCM4334.
Just what truly caught my eye is the component located in the center on top. The design of calls below it reveals that it is a wafer-scale bundle flip-bonded straight to the board. To me, that design appears like a WiFi chip format. […]
So we then compared the pattern on the board to one of the most likely Broadcom WiFi chips. The design of get in touches with matches a BCM4334 single-chip dual-band combo device.
The Broadcom BCM4334 is a single-chip dual-band combo that integrates 802.11 a/b/g / n with Bluetooth 4.0 and an incorporated FM radio receiver. It’s been utilized in the iPhone as well as iPad, and in Samsung gadgets in the past, and also it’s created for very little power intake in a compact size.
Though the Apple Watch shows up to have its own dedicated Wi-Fi chip, Apple suggests that it will certainly not manage to connect to Wi-Fi by itself. The Apple Watch will instead depend on the iPhone’s Wi-Fi connection, probably utilizing its internal Wi-Fi for communicating with a coupled iPhone under certain conditions.
It is outstanding that Chipworks was able to establish a component from the Apple Watch merely from a video, specifically considering that the gadget is still months away from delivering to customers. According to Apple, the watch will be released in early 2015, with prices starting at $$ 349.
