iPhone 6 Notes

Models A1549, A1586, A1589

iPhone 6 – Cumulus Digitizer Controller IC (u2401)
Meson Chip – No visual artifacts. No touch at all. DANGER! Easy to pull pad when removing. More technically challenging than the Cumulus chip to replace.

The problem is caused by oxidation. Reflow won’t fix oxidation.

Future Proof Shield does not appear to be a viable upgrade.

Red – Apple A8 APL1011 SoC + SK Hynix RAM as denoted by the markings H9CKNNN8KTMRWR-NTH (we presume it is 1 GB LPDDR3 RAM, the same as in the iPhone 6 Plus)
Orange – Qualcomm MDM9625M LTE Modem
Yellow – Skyworks 77802-23 Low Band LTE PAD
Green – Avago A8020 High Band PAD
Blue – Avago A8010 Ultra High Band PA + FBARs
Purple – Skyworks 77803-20 Mid Band LTE PAD
Grey – InvenSense MP67B 6-axis Gyroscope and Accelerometer Combo

Red – SanDisk SDMFLBCB2 128 Gb (16 GB) NAND Flash
Orange – Murata 339S0228 Wi-Fi Module
Yellow – Apple/Dialog 338S1251-AZ Power Management IC
Green – Broadcom BCM5976 Touchscreen Controller – Cumulus Chip
Blue – NXP LPC18B1UK ARM Cortex-M3 Microcontroller (also known as the M8 motion coprocessor)
Purple – NXP 65V10 NFC module + Secure Element (likely contains an NXP PN544 NFC controller inside)
Gray – Qualcomm WTR1625L RF Transceiver

Red – Qualcomm WFR1620 receive-only companion chip. Qualcomm states that the WFR1620 is “required for the implementation of carrier aggregation with WTR1625L.”
Orange – Qualcomm PM8019 Power Management IC
Yellow – Texas Instruments 343S0694 Touch Transmitter – Meson Chip
Green – 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.’
Blue – Cirrus Logic 338S1201 Audio Codec
