Tear Down

iPad 2 tear down

Right on schedule the feisty folks at iFixit got their hands on an iPad 2 and tore it down to its constituent parts. Doesn't look like there's any word yet on whether or not it uses an ARM Cortex A9 and PowerVR SGX 543 but hopefully that's forthcoming. Highlights include:

  • The thickness of these components -- especially that of the glass -- could drastically reduce the durability of the device, especially the glass' resistance to shattering. We'll see in due time if the percentage of folks with broken iPad 2 front glass is dramatically different than that of the original iPad.
  • Lifting off the LCD exposes the iPad 2's battery. We found a 3.8V, 25 watt-hour unit. That's just a hair more than the original iPad's 24.8 watt-hours, so any improved battery performance should be attributed to software and other hardware improvements.
  • We confirmed via software that the iPad 2 indeed has 512 MB of RAM.
  • The markings on the 1 GHz Apple A5 dual-core processor appear to be Samsung's, but Chipworks will investigate in the forthcoming days to find out for sure.
  • Other components that power the iPad 2:
    • Toshiba TH58NVG7D2FLA89 16GB NAND Flash
    • Broadcom BCM5973KFBGH Microcontroller
    • Broadcom BCM5974 CKFBGH capacitative touchscreen controller
    • Texas Instruments CD3240B0 11AZ4JT touchscreen line driver
    • Broadcom BCM43291HKUBC Wi-Fi/Bluetooth/FM tuner combo chip
    • S6T2MLC N33C50V Power Management IC
    • ST Micro AGD8 2103 gyroscope
    • ST Micro LIS331DLH accelerometer
  • There's also an Apple-branded 338S0940 A0BZ1101 SGP chip. This looks like the Cirrus audio codec Chipworks found in the Verizon iPhone, but they'll have to get it off the board to make sure!

What you expected or did Apple slap any surprises inside iPad 2?

Verizon iPhone tear-down -- could have been a world phone!

The fine folks at iFixit have already torn down the new Verizon iPhone and while there's a lot that hasn't changed and some changes we knew about, the biggest shocker so far is that Apple used the Qualcomm MDM6600 chipset which supports both Verizon's CDMA/EVDO and AT&T's GSM/HSPA+ -- but the GSM part isn't enabled:

  • This is the same chipset as the Droid Pro world phone. It supports both GSM and CDMA—which means that Apple could have supported GSM!

Apple TV (2010) tear down, similar to iPad inside

Apple TV (2010) barely made it off the shelves before the folks at iFixit sent us word they had a tear down under way. And it turns out this new Apple TV has a lot in common with Apple's other new iOS device this year, the iPad:

  • The Apple TV has 256 RAM, just like the 4th Generation iPod Touch and the iPad. The key marking of interest on the A4 processor package is "K4X2G643GE," which is identical to the marking found on the iPad.
