After iFixit disassembled the Apple Watch by last week, today we are entitled to that of the chip S1 included in Apple shows. It reveals different information and components as a Broadcom wireless chip, memory Elpida, Toshiba and SanDisk, in addition to a very detailed view of the entire S1.
In the center of the S1 is a processor designed by Apple, 0778 marked the PLA, as discovered ABI Research. The Broadcom BCM43342 chip is capable of managing Wi-Fi, Bluetooth, NFC, and FM radio, although the FM functions are not actually used. It shows also the NXP controller used to support NFC capabilities to apple pay and an AMS signal amplifier.
We already knew this but it’s now confirmed, Apple Watch embeds 512MB RAM Elpida, along with 8GB of storage, SanDisk and Toshiba.
The functions of the accelerometer and gyroscope are processed by the STM chip and the ADI controller manages the gestures on the touch screen. Finally, power is routed through a power control unit and a wireless charger IDT.
ABI said that the S1 chip is an “obvious variant of Apple’s smartphones,” it is a compression many parts normally reserved for those devices.
