![]() ![]() The widespread expectation that Apple will one day unlock the functionalities of NFC for functions other than Apple Pay also supports the prediction that a standard NFC controller would be used instead of a heavily customized device. ![]() As we progress through the full Deep Dive, we will try to understand the need for the additional accelerometer.īased on historical package markings of NXP NFC controllers in our archive as well as leaked iPhone 6 board images, we expect the NFC controller to be NXP’s PN544, or a variant thereof. In the iPhone 6 Plus, STMicroelectronics was missing, replaced by the new InvenSense part while Bosch is found supporting a 3-axis MEMS accelerometer function. In the iPhone 5S model we had noted these functions were split between two manufacturers, STMicroelectronics and Bosch Sensortec. One other notable observation - we found a 6-axis InvenSense gyroscope and accelerometer sensor. Based on our quick analysis, this is the same RF design strategy Apple used on the iPhone 5, iPhone 5S, and iPhone 5C. As for the other RF functions such as the RF antenna switches and power amplifiers, Apple once again uses multiple manufacturers like RFMD, Murata, Avago, and Skyworks. The only other RF support we see from Qualcomm is with their power envelope tracking IC, the QFE1100. The baseband support for both Apple iPhone 6 devices is from Qualcomm's Gobi Modem product line- the MDM9625M, with RF transceiver and RF receiver roles being supported by their WTR1625L and WFR1620 ICs respectively. Qualcomm makes their appearance in a few places, but not as a total RF solution. Qualcomm Gobi MDM9625M Baseband Processor ![]()
