Kermit

Jump to search
The main SoC is labeled CXD5315GG. The design is a stacked SoC with the SDRAM found in the same chip as the processor cores. Toshiba details their "Stacked Chip SOC" on their site. From reversing code and looking at FCC documentation, it appears that the internal name of the chip is "Kermit."
More information can be found at Chipworks.
According to the internal photos found in the FCC filings, it appears that an earlier version of the chip is labeled T9ML7MBG-S. This does not appear to be a standard model and is likely custom designed in partnership with Sony Computer Entertainment Japan. It is possible that Sony used this service from Toshiba in their design process which is why the prototype demonstrated in the FCC filing shows a Toshiba chip..
Pinout
Source is a iWork Numbers file.
The pinout is mostly reversed from the 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.
