    After the recent Apple Watch teardown, the experts over at Chipworks ended up taking a closer look at the parts that make the Apple Watch function. Their closer examination included X-Ray imagery of Apple’s new S1 system-on-chip design. Chipworks noted that with the new and proprietary technology that Apple built into the Apple Watch, the device appears to be the most sophisticated attempt at a wearable product to date. The firm continues by pointing out that many of the Apple Watch competitors run on relatively old embedded chips unlike Apple’s chip which was developed as a new package entirely for the Apple Watch.

    Since the S1 SoC was encased in thin metal, Chipworks ended up having to turn to X-Ray imagery to delve further inside before technicians could perform a careful and comprehensive disassembly. Initial images show a new STMicroelectronics 3mm-by-3mm land grid array (LGA) package with a 3D digital gyroscope and accelerometer located in the top left corner socket.

    The handling capacitive touch input duties are a result of the Analog Devices screen controller bearing the marking AD7166. The part isn’t listed on the company’s website but Chipworks did find a Product Change Notification for an “AD7166-202A Cortex M3 Based Cap” dated to April 2015. The document ended up being removed from ADI’s website.

    Last but not least the firm was able to discover a Texas Instruments OPA2376 Precision op-amp in what appears to be the Apple Watch heart rate sensor module.
