Returning for what is now a sixth appearance in an iPhone are STMicroelectronics paired accelerometers—the L3G4200DH 3-axis digital MEMS gyroscope and the LIS331DLH 3-Axis MEMS accelerometer. Apple feels very comfortable with both of these devices, and one wonders if Nintendo will continue to use these same ICs as well in its next console, the Wii U.
Speaking of familiar manufacturers, Dialog retains its power management IC socket with a new device, the Agatha II, or the D2013. Cirrus Logic also retains its audio codec in the iPhone 5.

For memory, the 32-GB of NAND flash found in the iPhone 5 torn down by UBM TechInsights was provided by SanDisk. The processor memory is found on a package-on-package (PoP) with the A6 applications processor. The PoP we found in our handset utilized Elpida's B8164B3PM 1-GB pow-power DDR2 (LPDDR2) SDRAM.
Lastly, Broadcom maintains its key design wins in the iPhone 5, with the major win being Broadcom's BCM4334 single-chip dual-band 802.11n, Bluetooth 4.0+HS & FM receiver combo chip providing the wireless connectivity to the handset. This same die was found within the Samsung Galaxy S3, suggesting that this combo chip is the current king of Wi-Fi.

What interesting to me is the retina display. Why doesn't Apple go all the way to 720 instead of 640? If so, the number of content available w/o resizing is a lot more. Well! I assume A6 is capable to render 720 content and there is little concern of storage.
@truekop- this is from
UBM TechInsights chief teardown engineer Chad Davis:
“Yes, there were two MEMS microphones at the top of the phone and a large condenser type microphone at the bottom of the phone that resembled a speaker.”
No word yet on the manufacturer, but I will try to find out.
BTW, a listing of the major components in the handset (not including MEMS microphones) was added to the end of the article:
"The iPhone 5 is touted by many as the most innovative iPhone since the original" The most innovative thing Apple could do with an iPhone is thumb a nose at Jobs' corpse and make it run Flash - and they still haven't done it
Why does it take multiple pages to read EE Times web articles? This one is 21 pages long!!! Come on EE Times, put the entire article on 1 web page and save us the unnecessary clicking. I know using the 'print' button will put everything on one page, but why do we need to do this extra step for every article?
