Apple designed a new processor specifically for the Apple Watch called the S1, and it’s this tiny chip that functions as the brains of the watch.
While we’ve already seen what the S1 looks like, we’re now able to see inside the chip itself thanks to a recent Apple Watch teardown conducted by ABI Research (via 9to5Mac).
It turns out that Apple managed to cram quite a bit of technology onto the S1 chip, with the teardown revealing that it includes Wi-Fi, Bluetooth, and NFC components, along with a custom Apple processor labelled “APL 0778.” There’s also a wireless charging sensor, a hybrid accelerometer and gyroscope sensor, 512 MB of RAM, and 8 GB of flash storage.
Here’s what the inside of the S1 looks like.
By packing all of these components onto a single, enclosed chip, Apple was able to design the Apple Watch to be weather and water-resistant, which we’ve already seen tested by the FoneFox team in Australia.
And, while Apple has managed to squeeze a ton of technology into a such a small chip, it’s not the only company to do so. Tech giants such as Intel have been hard at work creating specialised components that bring the same type of capabilities to their own wearables. At this year’s CES in January, Intel showed off a tiny computer that’s the size of a button specifically designed for smartwatches and other wearable gadgets.
