The Qualcomm MSM8255 Snapdragon Processor
The Qualcomm MSM8255 is a 45nm-based baseband/applications processor from the Snapdragon family of ICs. Based on the ARMv7, this single-core processor operates at 1 GHz. What makes this processor so interesting to us at the die-level is how the main die is IDENTICAL to the MSM7230. Comparing the images below show that the both dies feature the marking of ‘HG11-VN986’ with the key difference being that the MSM8255 is clocked to 1 GHz while the MSM7230 is clocked to 800 MHz.

On the left is the die photo of the MSM8255 with the die photo of the MSM7230 on the right. Notice the similarities in layout and design.
And now a closer look at the die images, notice the similarity in the die markings. MSM8255 on the left, MSM7230 on the right.

Micron Technology MT29F8G16ADBDAH4 8GB NAND FLASH
The internal storage of the Sony-Ericsson Xperia Play is provided by Micron’s NAND technology. We often don’t see Micron NAND in use in handsets as manufacturers such as Toshiba or Samsung get their fair share of design wins in this market. Of note is that this device is a single-level-cell (SLC) memory. SLC memory has advantages such as faster write speeds, lower power consumption and high cell endurance but these advantages come at a price, as SLC costs more per megabyte than the MLC offerings of Toshiba or Samsung. Sony Ericsson chose their memory on performance not cost.

Elpida B4064B2PD-6D 2Gb Low-power (LP) DDR2 DRAM
An ongoing trend in the recent teardowns we’ve done on handsets and tablets is the use of Low-Power memory in a package-on-package(PoP) architecture with the baseband/applications processor. We’ve seen this used in the recent RIM Blackberry Playbook tablet, the Apple iPad 2, and now the Xperia Play follows this trend in packaging. In this case, Sony Ericsson uses Low-power DDR2 DRAM with the Qualcomm MSM8255 processor in a PoP.
