There are different flavors of the iPhone 5. The model torn down by UBM TechInsights Friday (Sept. 21) was the A1428 model, optimized for the AT&T and Canada's LTE networks.
One of Apple's keys to success is their component selection. Under the direction of Tim Cook--then vice president of supply chain, now CEO--Apple developed supplier relationships from the very first iPhone that have only strengthened with every iteration of the handset. From a supply chain point-of-view, what this tells us is that Apple is relatively set in its partnerships with semiconductor manufacturers—making opportunities for those manufacturers not currently entrenched with Apple nearly non-existent.

For example, 10 manufacturers that had design wins in the original iPhone hold the same socket in the iPhone 5. Larger semiconductor companies like Samsung Electronics, Texas Instruments and STMicroelectronics supply a large portion of the iPhone 5's chips. Smaller companies like Dialog Semiconductor (provider of the main power management IC), Skyworks Solution (provider of the baseband power amplifier modules) and TriQuint Semiconductor (provider of the power amplifier modules) continue to gain massively with their socket wins inside the iPhone 5.
In fact, it is often major news when Apple does decide to replace a manufacturer on a key component selected for the iPhone. For example, it was newsworthy when Apple made the switch from utilizing Infineon-manufactured baseband processors to those from Qualcomm. That transition was made rather slowly, though, as Apple created a GSM version of the iPhone 4 using an Infineon baseband processor and a CDMA version of the same handset using Qualcomm's baseband chip. The switch to Qualcomm seemed imminent, as the IC selected for the CDMA version had GSM capability. To the surprise of few, the iPhone 5 continues to use Qualcomm baseband circuitry.
The iPhone 5 also heralds Apple's move into the 4G wireless landscape. Apple's latest handset is the first to incorporate LTE, matching the baseband capability of the third-generation iPad. Qualcomm has three design wins in the iPhone 5, all of them related to the company's LTE technology. The "crown jewel" of these ICs is the MDM9615. This device, manufactured at the 28-nm process node, is a mobile data modem that supports LTE (FDD and TDD), DC-HSPA+, EV-DO Rev-B and TD-SCDMA, making it a truly global baseband IC--capable of functioning on any carrier. With the MDM9615 are the natural pairs of the PM8018 power management IC and the RTR8600 quad-band transceiver with GPS. All three are part of Qualcomm's LTE ecosystem and were selected because of their interoperability.

How does Intel get away with claiming technology leadership with foundry regarding mobile SOC?
Iphone 5 shipping now ~50M units this year
4G MDM9615 manufactured in **28nm**
A6 in **32nm**
Intel last week Razr announced but not shipping
3G manufactured in **foundry 45nm**
Atom in **32nm**
Intel's 22nm finFET SOC does not ship until end of 2013. Something is very wrong. I hear moving design IP and transistor variation is the problem due to finFET being on bulk and requiring fin doping
@truekop- this is from
UBM TechInsights chief teardown engineer Chad Davis:
“Yes, there were two MEMS microphones at the top of the phone and a large condenser type microphone at the bottom of the phone that resembled a speaker.”
No word yet on the manufacturer, but I will try to find out.
BTW, a listing of the major components in the handset (not including MEMS microphones) was added to the end of the article:
Apple's handset are with the same processor or power management unit,such as: ipad, iphone, and apple and maybe itouch.Also use the same ios system with iphone and ipad.
I once test the power sequence of ipad 2 use the dialog semiconductor PMU.It's very hard when first test this.The datasheet is very long.
Power management is very critical for this battery powered system.I need charge my smart phone everyday which is samsung galaxy r.
Ipad is the largest iphone without telephone capacity.
Why does it take multiple pages to read EE Times web articles? This one is 21 pages long!!! Come on EE Times, put the entire article on 1 web page and save us the unnecessary clicking. I know using the 'print' button will put everything on one page, but why do we need to do this extra step for every article?
"The iPhone 5 is touted by many as the most innovative iPhone since the original" The most innovative thing Apple could do with an iPhone is thumb a nose at Jobs' corpse and make it run Flash - and they still haven't done it
What interesting to me is the retina display. Why doesn't Apple go all the way to 720 instead of 640? If so, the number of content available w/o resizing is a lot more. Well! I assume A6 is capable to render 720 content and there is little concern of storage.
@goafrit,Dylan, This was the article which speculated ADI has the MEMS microphone socket in iphone5.
There is three MEMS microphone in i-phone5.
I checked two MEMS Part no.
The first of three microphones comes out of the iPhone 5 along with the Lightning connector assembly.
It is safe to assume that the microphone located at the bottom front of the device is used for voice commands and voice calls.
PART NO NE2606 MEMS microphone seems to be in digital microphone
from Analog Devices or AAC.
If you know a more detailed information , sharing reveal.
The rear-facing microphone partners up with the rear-facing camera for recording video, and is also used for canceling out background noise when on calls.
Part no S949 369S MEMS microphone is similar to Knowles MIC Part no. (Analog)
and the other MIC information i don't get.
