The topside of the logic board reveals all of the iPad mini's integrated circuits. The large yellow-banded area is the next-gen 32nm version of Apple's A5 SoC, which was made to Apple's specifications by Samsung. Versions of this part have been used in the original iPad 2 and the third-gen Apple TV. The large orange region is a Hynix 16-GB NAND flash unit. The green portion indicates Apple's 338S1116 audio codec, made by Cirrus Logic. Not highlighted with color is a pair of blackish circuits along the top of the right-hand section. These parts are technically labeled Apple 338S1077, but they are actually a pair of Cirrus Logic Class D Amplifiers. Apple once again uses Broadcom for most of its networking, including the BCM4334 combo chip to deliver dual-band Wi-Fi a/b/g/n single-stream MAC baseband radio, Bluetooth 4.0 + HS and an FM radio receiver (it's also in the iPhone 5).
According to an iPad mini cost analysis by iSupply, parts for the 16-GB model with Wi-Fi only cost about $188. The suggested retail price for that particular model is $329.
