Every iPhone 3G chip named, illustrated in detail
Many have made guesses as to what chipsets are inside iPhone 3G, but research firms Portelligent and Semiconductor Insights have cracked the mystery and have explained each chip in one of the most detailed Apple product teardowns yet.
The examination reveals that the handset is indeed using an Infineon chipset for its GSM and 3G networking, though whether it's the same PMB8878 chipset mentioned in numerous leaks is unknown. Using a larger two-chip solution is unexpected, according to TechOnline analyst Allan Yogasingam, but may have been necessary for Apple to avoid falling victim to patent lawsuits by Interdigital that have plagued Qualcomm. That's not Infineon's only win for the new iPhone, however. It also handles the power management and, more importantly, the GPS chipset. Apple uses a PMB 2525 Hammerhead II chipset rather than examples from SiRF and other common GPS chipmakers. The component is accurate to "within meters" and prevents major positioning errors in cities, where buildings can bounce the signal and miscalculate the phone's location. The teardown also reveals that Apple has switched providers for the NAND flash memory that serves as permanent storage. Although Samsung has been tapped for large memory orders, it's Toshiba that is supplying the 8GB or 16GB of memory in each phone and uses a single chip for each 8GB of flash on the device. Samsung now provides only the system RAM. "To see Toshiba makes me wonder if that [Samsung] deal is no longer in place," says Greg Quirk of Semicondutor Insights. "Does this mean that Samsung is playing second string to Toshiba?" Many components remain the same. The Samsung ARM11 is still the iPhone's main processor, while Wolfson still provides audio through its own audio codec hardware even as it's rumored to be cut out of future iPods. These are signs that the iPhone 3G is "incrementalism at play" rather than an overhaul, says Portelligent's David Carey, even if Apple has learned from the iPod touch by consolidating everything into one board. Other companies involved with the iPhone 3G include Broadcom for the touchscreen controller, Marvell for Bluetooth support, as well as Linear Technology, National Semiconductor, Numonyx, NXP, Skyworks, SST, ST Microelectronics, and Triquint. |

1) I've read the sound quality through the headphones is much better. Are both new and old iPhone using the same Wolfson chip or is this one newer?
2) The mention of WCDMA/HSUPA is nice since the previous mention of the Inferion chips beign used did not have HSUPA capabilities. While HSUPA does nothing for my usage in the US right now it may help sell iPhones in other countries if this does mean that it has HSUPA. 3) "Uses a single chip for each 8GB of flash on the device." If the current 16GB model is really just 2x8GB chips sandwiched together, then in 6 months Apple could do an incremental update from 8/16GB to 16/24GB by using the same method. This is much better than having to wit an extra long time for Flash prices to fall for the denser, higher capacity chips. Last edited by solipsism; 07-12-2008 at 07:45 PM.. |

I was hoping for a Sony Felica RFID chip

This is not correct. Marvell supply the WiFi chip, Bluetooth is provided by Cambridge Silicon Radio (CSR).

Really!
That's not Infineon's only win for the new iPhone, however. It also handles the power management and, more importantly, the GPS chipset.Really? When was GPS more important than power management? I love Apple Insider for the news they post - but the errors, and sloppiness ruin it all. As for your "Mod Edit:" up there: lets just say you should've acted more professional; admit you made a mistake, say sorry, and don't do it again. |

Power management is required to get the phone to work properly. GPS is a feature that helps to sell the phone. Without the needed features, power management will be managing something that just sits on the shelves. |

The section you are discussing is not commenting on the actual features of GPS or Power Management it is say it is a WIN for the manufacturer because they are providing chips for both, i.e. more business than before. |

I didn't discuss the features of GPS or PM either. You did read my post did you not? MY point was referring to ipodrulz's post. He was the one who mentioned this at first. HIS point was that GPS was not more important than PM. My response to HIM (not the article) was that I don't agree for the reasons given. You want to get into more discussion? I'll gladly do that, but really, you first have to understand what is being said, and for what reason. |

If they used one chip. As stated in the article, they use 2x8GB chips for the 16GB model, not a single 16GB chip. Hence my statement that they could upgrade the capacity outside the usually exponential increases if they use multiple chips together with a special controller. For example, one chip is 8GB and the other is 16GB, that appear to the end user as 24GB of Flash. Imagine how other cell phones having a small amount of built-in Flash and an SD slot so they can support, say, 8GB of Flash + the 128MB of Flash it came with.

- the 8GByte iPhone uses 4 of these chips stacked in a single package The iPhone uses a single package, which limits its capacity to 16GBytes with current technology, whereas the Touch uses 2 such packages for a capacity of 32GBytes. Stacking upto 8 chips in a single package seems to be the current limit in stacking technology. Last edited by samurai1999; 07-13-2008 at 07:25 AM.. |

Also, I might add that I am disappointed by all this abuse of AI and each other in this forum. It's shocking that people would be so rude and critical. |

And I thought ifixit said it found an Intel NAND flash inside its iPhone. A few years ago Apple did invest $250M in each of five NAND flash companies.

It seems to me that it would still be too expensive in Nov (i.e. pre-Christmas). I'm hopeful the cost will have come down enough by Feb, when Apple usually has its post-Christmas/post-MWExpo sales booster shot.

The Intel Flash is a different chip - the one they've labeled 'Nymonynx' - which AFAIK is for code & scratchpad for the Baseband processor BTW, according to the Toshiba web-site, they'll have their 32GBit part in production sometime this quarter, so it *may* be available for a fall-update for the iPhone/Touch - I guess Apple would be very happy if they could get enough of it in time for Xmas... ![]() |

- if you look at the iFixit tear down, there's only one.. http://live.ifixit.com/Guide/First-Look/iPhone3G - the iPhone 2G certainly just has the one Flash package - and the Touch two - which is why the Touch can offer twice the capacity Apple obviously decided that the iPhone was ok with less - maybe for space reasons (i.e. it has a lot more to pack in) - or for other marketing reasons. And yes, they could offer sizes like 24GBytes if they wanted. |

They could, but I've not heard of anyone selling flash-based products that aren't simple powers of two, for example, 1, 2, 4, 8, 16, 32 is a series of doublings. Sizes in 3, 6, 12 and 24 GB are possible, but I've not seen it yet.

As was stated earlier Apple uses a variety of vendors for NAND Flash since even Samsung can't easily supply all of the memory required. The Numonyx win for NOR is fairly big as most people thought that would either go to Spansion or Samsung. |

I'm hoping, as the article stated, that this is just an incremental upgrade. Although, quite a good one. I still want a flip phone version.
![]() The natural upgrade path is an iPhone with two cameras for video chat via iChat, but the 3G networks need to be available in more areas than they are now to support this feature. The AT&T network bandwidth upgrades were a start in this direction. I'm sure, if bandwidth were no issue Apple would have had iChat out with the first generation iPhone. Oh and a 32Gb and 64Gb iPhone would be nice.

Cpu's are also suitable for this, if Apple cares to go that route at all. |

What about the accelerometers? Nobody talked about them. I guess they are the long metal-covered components? Who makes those???
