What's inside the M9?

What's inside the M9?

163.com has done a teardown of the M9. Maybe it's the first one, but I'm sure it's not going to be the last...

So what can we see inside the M9?  Well, the teardown isn't really complete because we cannot see things like the camera controller, which is on the secondary PCB with the camera, TF card slot, and SIM card slot:

Nicely hiding under the metal shielding
  

Moving on, #1 is, of course, the CPU:

Right in the middle is the Samsung S5PC110A01 1GHz Cortex A8 "Hummingbird" processor with KB100D00WM-A453 memory package.

Hey, where's the RAM/ROM??  It's built on the chip...so cool!  

The package marked "M9WS4 01693" to the right of the processor is, I guess, the WiFi and Bluetooth module hidden under an EMI cover..don't really want to tear that off, although it would be nice to know what chip it is.  The M9 does support WiFi B/G/N and Bluetooth 2.1, so everything's good.

How about the user memory...hey, no Samsung or Hynix SDRAM??!  No, the M9 will come with either an 8GB or 16GB TF card for loading your music, videos, and photos.

And FINALLY we have confirmation of the M9's audio!  It's the Texas Instruments TLV320AIC36, also called simply AIC36 and we see that to the left of the Samsung Hummingbird.


What else?  Well, turning over the main PCB, we have this:

From what I can see, we have...

  • TriQuint TQM6M9014 Quad-Band GSM / GPRS / EDGE-Linear TRP Tx Module (big chip, bottom left side)
  • TriQuint TQM676021 WCDMA / HSUPA PA-Duplexer Module for WCDMA 2100 band (small chip far left side)
  • Infineon 8824 XG616 X-Gold baseband processor (big chip in the middle)
  • Infineon "SMARTi" 5703 Transceiver (to the left and a little below the 8824 chip)

so there is all the communications hardware.  All of those chips, by the way, are also found in the Samsung Galaxy S and Google Nexus S.  The one difference that I can tell is that the M9 will support only the 2100 band of WCDMA (for Asia, Europe, Africa) while the other phones I mentioned include additional TriQuint "duplexer/amplifier" chips for other WCDMA bands.  I might be wrong about that, but that's the way I understand it.

I also don't know (or can't find) the ID for the chip marked "Japan Y8A0A" (just to the right of the Infineon 8824) and the chip marked "9L 35773" (bottom right corner).  Any ideas for those?  I suppose one of them could be the touchscreen controller.
