  • Finally, we get to the core of all things: the Apple-designed S4 system-in-package.

  • Good news, everyone! The S4 is secured only with screws, and pops right out—a welcome change from the fiercely-glued SiPs of years past.

  • As always, the package itself is encased in a solid block of resin, meaning most of its secrets will be difficult to extract. Thankfully though, the RF components remain a little more exposed:

  • Avago AFEM-8087 (likely front-end module)

  • OU JQ

  • YY MEH ECE (this looks like a Bosch part, likely the fancy new accel + gyro)

  • Avago E827 I2033 0836

  • ST Microelectronics ST33G1M2 32-bit MCU with ARM SecurCore SC300—the same eSIM we found in the last Apple Watch and in the iPhone XS and iPhone XS Max.

最后，我们终于拿到了这玩意的核心：Apple 设计的 S4 SiP。

好消息，小伙伴们！S4 只是由螺丝固定，可以直接弹出——这是和去年的强力胶固定的 SiP相比是个好的改进。

与往常一样，芯片本身包裹在坚固的树脂块中，意味着它的大部分秘密都难以了解。值得庆幸的是，RF组件仍然暴露在外：

Avago AFEM-8087 （可能是前端模块）

OU JQ

YY MEH ECE（这看起来像博世的部分，可能是花哨的新加速器+陀螺仪）

AE827 I2033 0836

ST 微电子 ST33G1M2 32位 MCU 配备 ARM SecurCore SC300 —— 就和我们在上一代 Apple Watch 和 iPhone XS 还有 iPhone XS Max 上找到 eSIM 一样。
