  • 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.

Und endlich kommen wir zu des Pudels Apples Kern: das hauseigene S4 System-in-Package.

Eine gute Nachricht, Freunde! Das S4 ist nur mit Schrauben befestigt und lässt sich leicht entfernen. Das ist eine willkommene Abwechslung zu den gnadenlos eingeklebten SiPs der vergangenen Jahre.

Wie immer ist das Package selbst in einem festen Harzblock eingeschlossen, so dass die meisten seiner Geheimnisse schwer zu lüften sein werden. Glücklicherweise bleiben die HF-Komponenten jedoch etwas besser sichtbar:

Avago AFEM-8087 (wahrscheinlich ein Front-End Modul)

OU JQ

YY MEH ECE (sieht aus wie ein Teil von Bosch, wahrscheinlich der coole neue Beschleunigungssensor und Gyroskop)

AE827 I2033 0836

ST Microelectronics ST33G1M2 32-bit MCU mit ARM SecurCore SC300—die gleiche eSIM, die wir in der letzten Apple Watch sowie im iPhone XS und iPhone XS Max gefunden haben.
