When Apple introduced the iPhone 5, Senior Vice President of Worldwide Marketing Phil Schiller noted a number of new methods being used for noise cancellation from solutions using the device’s third microphone to an updated “noise-cancelling earpiece” and the addition of wideband audio. We know from reports earlier this month that Apple is not including noise cancellation technology from Audience, as it did in previous iPhone models. While we do not know exactly what powers the iPhone 5’s enhanced audio system, Chipworks discovered a second Cirrus chip being used in its recent teardown:

  • Apple 338S1077 Audio CODEC. This is a wafer-scale device by Cirrus Logic.  They have long held this private-label package with Apple.
  • Apple 338S1117 Cirrus Audio Chip

It is very possible that Apple’s new, in-house noise canceling technology uses this new Apple-branded Cirrus chip.

  • Sprint confirms no wideband audio support for iPhone 5
  • Sharp says its producing ‘adequate volumes’ of iPhone 5 displays as shipping times slip for international rollout
  • Chipworks confirms that Apple is still using Sony and Omnivision cameras in iPhone 5
