The iPhone 4, at its core, is tantamount to Apple offering a handheld version of the iPad, according to a report.
The iPhone 4 has so many internal similarities to the iPad that it could, in this respect, be labeled an iPad Nano, according to analysts from TechInsights cited in an article from EE Times.
In a teardown of the iPhone 4, TechInsights found "at least seven chips from the...Apple tablet," according to the report. TechInsights will come out later with a full report on the teardown of iPhone 4. TechInsights is a division of United Business Media, the publisher of EE Times.
While it's well know that, like the iPad, the iPhone 4 uses the A4 chip, Apple's latest phone also reuses a number of other iPad parts including a Broadcom Bluetooth FM radio combo chip (the BCM4329), Broadcom GPS device (the BCM4750), and Cirrus Logic audio codec (the 338S0589), according to EE Times.
The iPhone 4 and iPad also share common flash chips--a Samsung 256 Gbit NAND flash device (the K9TFG08U5M) and a combo device from Numonyx, EE Times said.
"Design reuse is clearly a big focus for Apple these days. For example, the iPhone 4 continues Apple's use of baseband and transceiver chips from Infineon despite a highly competitive market for such chips. The handset also uses the same Dialog power management chip Apple put in the iPad," EE Times said.
