This is for DevKit. Retail and TestKit are different:
 +
* The DevKit carries 1 GiB of LPDDR2 DRAM (usually referred to as the "main memory"). The retail unit and TestKit carry 512 MiB of LPDDR2 DRAM.

 +
Codec Engine is a media processor configured with multiple cores. Only the specific processing of the specific libraries is processed through Codec Engine instead of CPU.

The pinout is mostly reversed from the [http://wololo.net/talk/viewtopic.php?p=402775 PCB delayer] and is based off of PCH-1XXX on the IRS-002 board. It may not include some pins only used in other Vita models.

As other key units, the custom SoC includes the features below:
   −
=== CPU ===
+
* Direct Memory Access Controllers (DMAC)
 +
* AVC Decoder
 +
* A video out interface
 +
* Misc input/outputs interface etc.
