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?
