On the morning of May 8th, after the Apple Watch was released on April 24th, foreign media and analysts disassembled and analyzed the product. They found that Apple’s S1 chip designed for watches was still manufactured by Samsung.
After the listing, Apple Watch's foreign website iFixi disassembled it. Semiconductor analysis vendors Chipworks and ABI Research continued to analyze the Apple Watch S1 chip.
Apple Watch chip disassembly
Chipworks released a report last week explaining the internal structure of the S1 chip, which contains 512MB of running memory, using WiFi chips from Broadcom, and accelerometers/gyros from STMicroelectronics.
Today, Chipworks once again announced its report on S1, which has only 30 separate components in a 26mm x 28mm chip, which Chipworks calls "quite an accomplishment." A motherboard is attached to all components, covered with silica or spherical alumina, which has never been seen on other products.
The application processor of the model APL0779 on the S1 chip (equivalent to the CPU and GPU parts) production process is from Samsung, for the 28nm process. Of course, the current 28nm is not a new technology. The chip of this process has appeared in 5s. The A8 chip of Apple's iPhone 6 and 6 Plus uses a 20-nanometer process. The use of a 28nm process chip means that the processor size in next-generation devices is likely to be further reduced and performance will be further enhanced. Apple chip technology has a 14-nm process level. .
Although the Apple Watch has only been on sale for two weeks, rumors about the next generation of Apple Watch have begun to appear. It is said that the health sensor that was absent in the first generation of Apple Watch will appear in the second generation, which may allow users to monitor stress levels. Information such as blood pressure and oxygen content. And this watch is said to appear in 2016.
