[* black] More ICs await us on the back of the logic board:
[* red] Qualcomm WFR1620 receive-only companion chip. Qualcomm [https://www.qualcomm.com/media/documents/files/the-qualcomm-difference.pdf|states|new_window=true] that the WFR1620 is "required for implementation of carrier aggregation with WTR1625L."
[* orange] Qualcomm PM8019 Power Management IC
[* yellow] Texas Instruments 343S0694 Touch Transmitter
- [* green] AMS AS3923 Boosted NFC Tag Front End
- [* icon_note] We believe that this is simply a small revision of the AMS [http://www.ams.com/eng/RF-products/RFID/AS3922|AS3922|new_window=true], which allows for "payment functionality in ultra-small form factors such as SIM and µSD".
+ [* green] AMS [https://www.ams.com/eng/Products/NFC-HF-RFID/NFC-HF-Booster/AS3923|AS3923] NFC Booster IC designed to “improve performance of existing NFC controllers for challenging environments such as mobile and wearables” and also delivers “less restrictive antenna design requirements”.
+ [* icon_note] Seems this chip is a kind of a NFC frontend as it also has peer to peer build in.
[* blue] Cirrus Logic [https://chipworks.secure.force.com/catalog/ProductDetails?sku=APP-338S1201&viewState=DetailView&cartID=&g=|338S1201|new_window=true] Audio Codec
[* icon_reminder] A big and hearty mega-thanks to our pals at [http://www.chipworks.com/en/technical-competitive-analysis/resources/blog/inside-the-iphone-6-and-iphone-6-plus/|Chipworks|new_window=true] for helping us ID all of this tech. We definitely couldn't have done it without them!
