CXD90025G
SCEI CXD90025G
Custom ASIC from Marvell (it even has the 88EC120-BNS2 Marvell naming)
Source: Decapped by Chipworks, see their section on "Network Co-Processor"
Note: It's likely that this chip is way more than simply a "Network Co-Processor"
It is connected to its own DDR3 worker RAM K4B2G1646E-BCK0, the main serial flash MX25L25635FMI-10G and SATA bridge MB86C311B etc. see also File:PS4_-_SAA-001_diagram.png
This secundairy processor was nicknamed MediaCon by the community before any official release because of its role of handling media (online Wireless/GbLAN, Bluray Drive and Harddrive) even in standby. It is not its official name (which is unknown at this moment).
Likely connected to APU by PCI_Express x4 / [HyperTransport] or simular highspeed, low tracecount bus (Marvell ASIC suggests PCI_Express).
