iPod touch 3G teardown reveals 802.11n chip


A newly-published teardown of the third-generation iPod touch by iFixit has revealed that the player contains an 802.11n-capable Wi-Fi chip, despite being listed as an 802.11b/g only device. According to the article, the iPod touch 3G sports a Broadcom BCM4329FKUBG wireless chip, which the manufacturer states is n-compatible. Notably, this chip appears to be more advanced than the 802.11 a/b/g-only Broadcom BCM4325 chip found in the iPhone 3GS, and also offers support for Bluetooth 2.1 +EDR and an FM receiver and transmitter. In addition, iFixit found enough space left at the top of the board—6mm x 6mm x 3mm—to house the video camera found in the fifth-generation iPod nano, but not enough to fit a more robust sensor like that found in the iPhone 3GS. Finally, the iPod touch’s ARM processor is labeled 339S0075 ARM, possibly indicating a later version of the processor found in the iPhone 3GS, which is labeled 339S0073 ARM.

Wow. That makes it seem more than ever like this is a beta version of the 3G touch rather than the one they wanted to release. Who knows if Apple will ever activate any of these features, or if they will charge extra to turn them on later. I may just have to wait and see. Certainly come January they will be ready to release the touch they should have had ready this week, complete with 802.11n, a camera, and FM reception.

I sense another future apple tax, oops pardon me a paid upgrade, to activate these features - lol

remember wait 3 months and the upgrade will be half price - just like 3.0/3.1

Silly question, but I cannot tell from Apple’s video. Since the Touch does not have a microphone, the Voice Control only works with their earbuds & microphone attached?

#3: Yes.

Just because the device has a chip that is capable of 802.11n, EDR and FM, it doesn’t mean the rest of the device will be capable.
There may be technical hardware restrictions on the antenna, and Apple will have to develop some sort of FM drivers and a Radio App to access these features.
Without an external antenna an FM Transmitter is almost useless, and Apple aren’t in the market for sub-par features.

Why is they no mention of Ram? Can anybody confirm that the 32gb & 64gb models have 256mb Ram,like the 3GS.

Wow it’s funny how people get all uppity on something that happens all the time. There are other things required for 802.11n compatibility OTHER than just the chip. If a company can get those chips cheaper in bulk than a comparable 802.11b/g chip, they will go for the one that also does 802.11n purely based on price. If 802.11g is what they were going for, that is what it was engineered for. You see this happen all the time, its just people don’t tear all of your electronics down and analyze every chip.

They did NOT choose an 802.11 chip and engineer a reference design AROUND that chip. They engineered a design based around specs they wanted (802.11g in this case) and the chips are selected later.

@7 That might make sense except that this is Apple we’re talking about. We’ve already seen a past case of Apple shipping the touch with such hardware potential (in that case, bluetooth) and charging consumers an upgrade/unloack fee to enable it down the road. They did the exact same thing with 802.11n for their MacBooks.

They’ve done it before, they’re probably doing it again.

Just bought the 64GB iPod touch today.  Nice upgrade.  I especially like the “Zoom” feature in the accessibility options.  Voice Over is kind of hard to get used to the new gestures.

anyone know when this comes out?

I hope a software update will open FM radio in the 64GB touch

Couldn’t iLounge at least fix my typo for the front page (unloack indeed)? ;-)

#10 it came out on 9/9/09 and it may be in your local stores or not make sure to check the model numbe for 32GB because some stores still are carrying the older 32GB model. I know my Best Buy still had the older 32GB so I had to return it and buy it on the official Apple Store and it will be shipped in a matter of hours I cant wait!

Well they can use the headphone as an external antenna for the fm. I had a motorola cell phone and it also had no external antenna for the fm, but it used the headphone as an antenna for the fm radio feature. Apple will not install a wireless chip which supports fm transmission without any reason. Apple will be releasing the 4.0 OS for iphone 3GS and ipod touch 32, 64 3rd generation models and I think they might enable the fm feature in that. Hope they enable it in 4.0 OS.
