A) A4 Chip
Apple introduced its new A4 chip with the first version of the iPad. It’s a “system on a chip” that integrates the central processing unit, the graphics core, and the memory controller. The iPad can work for 10 hours on a single charge, and Apple says one reason for this is that the A4 chip is so power-efficient.

B) Flash Memory Chips
These two chips provide storage for the user. According to Chipworks, a semiconductor and electronics consulting company based in Ottawa, Canada, these chips are Samsung’s first-generation flash memory, and don’t appear to represent any technology advancements.

C) Touchscreen
Similar to the architecture of the iPhone 3G, these two chips are responsible for the iPad’s touchscreen.

D) Power Management
Chipworks suspects that this chip is involved in managing power for the iPad.

E) Possible Audio Processor
This chip is branded by Apple, making it difficult for researchers to identify it. However, because it bears numbers associated with audio codecs in other brands, experts suspect that it is the audio processor for the device.
