A Broadcom BCM4329 combo Wi-Fi/Bluetooth chip may also be used in the iPad, according to speculation from one on-line teardown site after seeing pictures released by the Federal Communications Commission.

Carey praised the unique stair-step pattern molded into the aluminum back panel of the iPad. It provides greater ruggedness for the case as well as a way to secure multiple subassemblies used inside the design.

Among other iPad design wins, Cirrus Logic had an audio codec, Carey said Linear Technology had two charger ICs and he speculated Dialog Semi had a power management chip.

Based on pictures from the FCC, the 3G cellular data board for the iPad "looks similar to what's in 3GS iPhone right now," Carey added.

Indeed, many of the chips appeared in versions of the iPhone and iPod. "They have done reuse wherever possible," said Carey.

The iPad Carey examined used a 1024x768 pixel LCD he speculated was made by Sanyo-Epson Imaging, now part of Sony. LG Electronics also provides displays for the iPad.

One non-technical conclusion Carey shared after tearing down the tablet: "I want one."

According to market watcher iSuppli, Apple could sell as many as 7.1 million iPads this year, though International Data Corp. estimated 2010 tablet sales at six million for the entire industry.
