iPhone 4 demolish divulges design recycle
The recent Apple iPhone 4 could very well be called an iPad since it uses at least seven chips from the admired Apple tablet, according to forecasters from UBM TechInsights that have done a flatten of the latest smart phone. STMicroelectronics won a popular design win for its MEMS gyroscope in the phone.
Similar to the iPad, iPhone 4 uses Apple’s A4 as itsapplication processor. Nevertheless, it uses an edition with twice the memory—512MB of Samsung Mobile DDR SDRAM. Purposely the part uses the Samsung K4X4G643GB, a package-on-package stack of two 2Gbit die.
Design reuse is evidently a big focus for Apple these days. Such as, the iPhone 4 continues Apple’s use of baseband and transceiver chips from Infineon although a exceedingly cut-throat market for such chips. The phone also uses the same Dialog power management chip Apple put in the iPad.
The iPhone 4 also salvages numerous other iPad parts together with a Broadcom Bluetooth FM radio combo chip (the BCM4329), Broadcom GPS device (the BCM4750) and Cirrus Logic audio codec (the 338S0589). The iPad and iPhone 4 also share in common two memory chips—a Samsung 256 Gbit NAND flash device (the K9TFG08U5M) and a combo gadget from Numonyx.
