  • After learning the finer points of US vs. EU sandwicherie, let's tuck into the (mostly familiar) US silicon layers:

  • Apple APL1W01 A14 Bionic SoC with Micron MT53D512M64D4UA-046 XT:F 4 GB LPDDR4 SDRAM layered over it (same as the iPhone 12/12 Pro)

  • 1UED, most likely a U1 ultra-wideband chip similar to the USI chip in other iPhones

  • STMicroelectronics STWPA1-3033ABM wireless charging IC, possibly something similar to their STWBC-EP chip

  • KIC M224 BE0408 TWNA 12031, 64 GB of Kioxia NAND flash memory

  • Qualcomm SDR865 5G and LTE transceiver

  • Qualcomm SDX55M 5G modem-RF system and SMR526 intermediate frequency IC

  • Apple APL1094 power management IC

Après notre apprentissage des subtilités de l'art du sandwich américain et européen, jetons un œil aux couches de silicium US (familières pour la plupart) :

Système sur une puce (SoC) A14 Bionic APL1W01 Apple, posé sur SDRAM LPDDR4 de 4 Go D9XMR Micron (la même que dans les iPhone 12/12 Pro)

1UED, très probablement une puce ultra-wideband U1 similaire aux puces USI d'autres iPhone

CI de charge sans fil STWPA1-3033ABM STMicroelectronics, peut-être quelque chose de similaire à leur puce STWBC-EP

KIC M224 BE0408 TWNA 12031, 64 Go de mémoire flash NAND Kioxia

Émetteur-récepteur LTE et 5G SDR865 Qualcomm

Système modem-RF 5G SDX55M et CI de fréquence intermédiaire SMR526 Qualcomm

CI de gestion d'alimentation APL1094 Apple
