Sleep om te herschikken

More ICs await us on the back of the logic board:

Qualcomm WFR1620 receive-only companion chip. Qualcomm states that the WFR1620 is "required for implementation of carrier aggregation with WTR1625L."

Qualcomm PM8019 Power Management IC

Texas Instruments 343S0694 Touch Transmitter

AMS 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”.

We believe this chip is an NFC frontend to improve performance in noisy environments using 'active peer to peer bit rates [up to] 212kb/s.'

Cirrus Logic 338S1201 Audio Codec

A big and hearty mega-thanks to our pals at Chipworks for helping us ID all of this tech. We definitely couldn't have done it without them!
