The iFixit team is back at it again, and they have torn down the iPhone 4S for us all to see. Want to know what that A5 chip looks like inside the device, or that new 8MP camera? They take us through it step by step.

  • Apple A5 Dual-core Processor (more on this later)
  • Qualcomm RTR8605 Multi-band/mode RF Transceiver. Chipworks has provided us with a die photo.
  • Skyworks 77464-20 Load-Insensitive Power Amplifier (LIPA®) module developed for WCDMA applications
  • Avago ACPM-7181 Power Amplifier
  • TriQuint TQM9M9030 Multi-Mode Quad-Band Power Amplifier Module.
  • TriQuint TQM66052 (possibly a PA-Duplexer Module)

And yes, 512MB of RAM. So no huge surprises, but hit the links below for more from both iFixit and Chipwor

Chipworks Posts Teardown Images of Apple iPhone 4S

Images and analysis to be updated continuously on Chipworks and iFixit web sites.

Ottawa, Ontario, October 13, 2011 – Chipworks announced it has posted initial results of its Apple iPhone 4S teardown and will continuously update images and information as it comes out of its labs over the next 48 hours. The focus of this analysis is on the die level to provide information that is not readily available at the board level.

Images and information from the teardown will be posted at, and select images are being shared with iFixit at

A full analysis will be available on the Chipworks website including de-capsulated images of the chips in the iPhone 4S, die layouts, and information on the process technology used to build some of the devices.

“The iPhone 4S contains a lot of the same devices observed in the iPhone 4 and the iPad 2 making this somewhat of a technology hybrid between the two.” says Jim Morrison, Product Manager at Chipworks, “we’re going to be looking deeper to confirm other similarities and differences. For example, we will confirm whether the A5 chip found in the iPhone 4S is still being fabricated by Samsung or has been moved to TSMC’s 40 nm low power process.”

Chipworks is the recognized leader in reverse engineering and patent infringement analysis of semiconductors and electronic systems. The company’s ability to analyze the circuitry and physical composition of these systems makes it a key partner in the success of the world’s largest semiconductor and microelectronics companies.
